china lcd module brighter than the LED. The organic layer than the OLED corresponding

OLED brighter than the LED. The organic layer than the OLED corresponding to the LED thin many inorganic crystals , and thus the conductive layer of the OLED and the emission layer may be a multilayer graphic lcd modules structure. In addition , LED and LCD glass as the support needed , and the glass will absorb some of the light. OLED is no need to use glass.
OLED do not need to use the LCD backlighting system ( please refer to LCD ( liquid crystal display ) works ) . LCD will selectively block certain backlighting work area , so that the images appear, and it is by self-luminous OLED . Because OLED without OLED Display backlighting system , their power consumption is smaller than LCD (LCD power consumption of the backlight system for most ) . This is for the battery-powered device ( e.g., a mobile phone ) is particularly important .OLED easier to manufacture , can be made into larger size. OLED is a plastic material , thus making it larger than the area can be flaky . And you want to use so much pave crystals and put them , they have much more difficult .OLED very wide field of view , up to about 170 degrees. The LCD is working to block the light , so there is a natural barrier in some observation angles . OLED itself capable of emitting light , so have a lot of wide range of sight .

Tsingtek china lcd module are required to use the same power supply and drive technology

Whether standard or soft OLED, are required to use the same power supply and drive technology. To understand the interaction of OLED technology , functionality and power supply between its must -depth analysis of the technology itself. OLED display is a self light-emitting display technology , all without any backlighting. graphic lcd modules materials are used in the chemical structure of suitable organic materials. OLED technology requires a current control method for driving a light emitting diode OLED has the standard (LED) is quite similar electrical characteristics are dependent on the brightness of the LED current . To turn on and off and control the OLED Display  need to use a thin film transistor (TFT) control circuit. Advanced power saving mode to achieve maximum efficiency and any battery powered device , only when the maximum overall efficiency of the converter to the load current range for the operation, in order to achieve longer standby time of the battery , which is particularly important for the OLED display . Rendering the OLED display consumes maximum power all white , the display color for any other current is relatively small , because only the needs of all white red, green , and blue sub-pixels are all lit .

Shot ultra-stable hard-screen LCD TV is king

Today's flat panel TV market turns out to be squandering charming eyes . Not only in terms of price , quality , performance is fairly mature traditional LCD TVs are very active, and accelerate the adoption of LED LCD TVs and 3D TVs also debut should not be underestimated . So for consumers, how do we buy into a versatile products?

LCD TV panels accounted for more than 70% of the cost , is the core component of LCD TVs. Notably , the panel on the market are "hard screen" and "soft screen " points. Soft -screen liquid crystal molecules recovery is slow , the screen is unstable. In contrast, hard screen has a clear advantage : When the touch , no " Watermark " phenomenon. Even when subjected to external forces beating and shaking , it will not interfere with a hard screen showing a smooth, clear picture. For this reason , IPS hard screen technology also has ultra-stable hard screen , and " touch the selected hard screen " LCD TV selection method has also been widely used.

LED TVs are hot at that time , it has a stylish ultra-thin , fine quality , green energy-saving features, is the perfect choice for many consumers eyes. However , note that , LED LCD TV market is divided into direct type and edge-lit . The difference is that side- advantage in the slim design and cost , but also the most widely used applications ; rather direct style is more concerned about the quality of user choice. Also , buy a high- quality LED LCD TV screen to distinguish between hard and soft .Graphic LCD Display As the molecular conversion speed hard-screen LCD screen 10 times faster than the soft , so when displaying fast motion picture , better able to ensure a clear , smooth and realistic effects .

For in the initial stage of 3D TV , the general view is that the industry , 3D TV on the LCD screen of the requirements will be more stringent than 2D TV. Because the 3D TV technology is relying on the principle of super-fast screen refresh rate and shutter glasses fit , so that the two vice complete picture formed at different times of persistence visual overlay. For this reason , many manufacturers have chosen the response speed of the liquid crystal molecules advantage of IPS hard screen panel. With Trumotion480Hz technology , 3D realization of a second screen is refreshed 480 times , and through the " flashing light " technology compatible , to minimize the result of his eyes " about interference " occurred " ghosting and dizziness ," and so on. Therefore, in the 3D TV can withstand a higher price , the one based on 3D TVs IPS hard screen technology will become the first choice .

Bluntly "LCD TV screen is the pick ! ", Although somewhat definitely speaks these words , but considering the merits of the Serial Lcd Display Module and image quality for LCD TVs have a decisive impact on the election -screen LCD TV really is purchase of a key ring .

TV purchase these your attention yet

LED is better than LCD picture quality

This rumor logic is clear: Since the LED TV is the latest out, then the quality is certainly better than in the past with CCFL backlight ( commonly known as LCD) LCD TV is good. What this really true ?
As mentioned earlier , LED TV's biggest advantage is long life , high brightness, low power consumption, small size. As to the quality better than that of LCD, but also depends on the spectral characteristics of the LED , high- performance focusing on only those LED TVs , by using particles of a high-performance LED , combined panel and picture quality processing techniques to achieve high quality. In addition , in the past , when the LED TV does not appear , there are many high-end LCD TV by using a high performance CCFL backlight and panel to achieve a high quality , which is the same reason.

5 = buy buy LCD TV panels


LCD panel LCD TV sets accounted for more than 70 % of the cost , this is not to deny the fact . But does that mean that buying a TV panel is to buy it ? The answer is of course no.
The following reasons:

1 , the LCD panel only occupy a larger share of the costs of the machine . For "good" TV and " bad" TV is the same.

2 , bucket theory tells us that the key factor in determining good or bad thing is how short the shortest piece of board , rather than how long the longest piece of board . So if only the LCD panel is good,20x4 lcd display the other bad parts , but also can not make a good TV.

3 , even the best LCD panel plant , out of the products have quality differences. Can not say that so and so long as it is produced in a liquid crystal panel is good, so and so is the production of LCD panels bad .

6 , hard screen than the soft screen strong , impact

This statement is more popular in the last year , many consumers once considered hard-screen LCD TV in front of the screen adds an extra layer of protection , so the more solid , impact resistance. At that time a lot of sales in stores selling television sets in order to prove himself with a "hard screen" , will hand to knock , push the TV screen , in order to prove their strong sales of the TV screen , and durable.
In fact, the difference between hard and soft-screen in the direction of the liquid crystal molecules are arranged just different decision . Hard screen and no additional protective layer on the surface, so it does not seem to be more solid than the soft screen , impact resistance.

In fact , the biggest difference between hard and soft-screen or display different characteristics , focusing on hard screen color reproduction of authenticity , but generally not as soft contrast screen ; soft screen contrast generally good , but the color is more obvious tendency . In fact, this is the difference in style ,Character LCD Modules and physical structure , is strong, durable , and no significant relationship .

LCD panel can show the number of colors

In the purchase of Graphic LCD Display TV, in addition to often see the screen size, resolution, brightness, contrast, response time specification parameters, often we will find that there is a word called "Colors." Different brands and models of LCD TVs for the description of the number of different colors, the corresponding figure is night and day to another, some marked only 16.7 million, some labeled as 1 billion, as well as a more exaggerated marked as 28.9 billion. So, what these numbers represent what the meaning behind its products can reflect much difference between it?
 
LCD TV can show a number of colors by what factors determine it?

First, we have to be cognizant of two completely different concepts, one is the LCD panel can show the number of colors, an internal circuit is capable of handling the number of colors, both of which are related to the lcd modules TV can be displayed delicate color gradation extent.

LCD panel can show the number of colors

LCD panel can be expressed by the number of colors inherent physical characteristics of the panel decision. According to the basic principle of the liquid crystal display image, the liquid crystal molecules by two glass substrates attached to the upper and lower driving voltage between the occurrence of the corresponding deflection angle, the light through the liquid crystal layer when the angular deflection according to the size of the liquid crystal to obtain different levels of transmission, the This is reflected in the panel have different levels of gray scale contrast. When light passes through the liquid crystal layer needs through the filter, the filter corresponding to each pixel is divided into red, green, and blue small squares, the original white light from these small squares separated out after filtration , the entire panel can present a variety of colors, which is colorful screen display panel simple principle.

LCD driving principle


The liquid crystal panel of the full color image forming process
From the above description it can be seen, the panel can be expressed by the number of colors of the liquid crystal drive deflection angle of the degree of sensitivity. Assuming deflection voltage variation and LCD is divided into 256 steps, then when the voltage generating a step change in the liquid crystal along the angle of deflection of an order, so the panel can show a color change of order; However, if the voltage to produce a step change When the liquid crystal molecules did not produce a corresponding first-order angular deflection, then no one step on the performance of the panel color changes.

Therefore,OLED Module  there is a liquid crystal panel, the number of colors can be expressed concept, which is determined by the panel of the innate physical properties. As in the display people tend to care about what is TN panel or a VA panel, largely because TN panels can be demonstrated by the number of colors as rich VA panel, showing a level of less than VA panel screen delicate vivid. Of course, the above description is idealized assumption, I just hope that this can be expressed in a more intuitive and easier to describe the problem.

How to solve the mosaic screen Huaping phenomenon of aging and

LCD splicing screen because it is easy to work long hours to make certain pixels overheating, once more than the limit will lead to permanent damage , which formed often say " dead pixels ." Since Character LCD Module splicing screen pixel is constituted by the LCD , so when the full load continuously for 96 hours or more , it will accelerate to its aging , even when serious burn. So, if you must work long hours , it is best able to let it rest for a while intermittent , or often in different time intervals to change the screen contents appear , because the state is waiting for work to reduce the brightness , or in screen saver mode operate under a will , which require little effort not only retard aging of the LCD screen , and avoid hardware damage occurred .

In addition , LCD whether any problems , prohibit self- assembled LCD splicing screen ( special is especially interested in the general DIY ) , once the LCD splicing screen is not working properly you can find vendors to help solve. Since the LCD backlight assembly transformer off after a certain time is still possible with the 1000V high voltage ( albeit micro-current ) , not specialists if not handled properly may result in failure of the new component .

Moreover , COG LCD Module screen is very fragile delicate, impact resistance is poor. This is because the LCD contains a lot of precision glass element and agile delicate electrical components , once subjected to strong shock will cause the LCD screen , and other related components damaged. So be sure to avoid strong impact shocks. At the same time , but also pay attention not to exert pressure on the LCD screen surface , such as a screen with a finger pointing the site , it is very likely to cause dead pixel number of moves.

Besides, if find LCD splicing screen surface dirt , accurate method should be used to remove dirt . It is best to use a medium soft, non-fibrous material, such as cotton , lens tissue or a soft cloth, and then gently wipe stained with a little glass cleaner , prohibit the use of alcohol, a class of chemical solution , nor can the rough cloth or paper items , as these substances prone to scratches. Here to remind everyone that , do not spray cleaning agents directly to the surface of the screen appear , it is very easy to flow inside the screen causes the OLED Display screen internal short-circuit fault , resulting in unnecessary losses.

Teach you choose the best low-cost monitors

LCD monitor when using the computer in our daily electronic devices take a long time to face , and the display is radiated more products , for large brands of LCD monitors its internal layout is more reasonable , done in the electromagnetic radiation shielding is in place .

Metallic shield layer is indispensable to monitor the original low

Electromagnetic radiation is the electromagnetic energy in the form of electromagnetic waves propagating through space phenomenon , OLED Display it is commonly referred to as the propagation velocity of light. Electromagnetic radiation according to their wavelength, frequency arranged in a number of frequency bands , the formation of the electromagnetic spectrum . The higher the frequency the greater the energy of the quantum of radiation and its biological effects is stronger .

The liquid crystal display screen electromagnetic radiation best approach is covered in a metallic shield radiation . We understand that the metal shield may be cut off the spread of electromagnetic radiation , but also conducive to heat transfer . From disassemble the figure we can see that the metal layer does not need very thick , just and accurate coverage of the radiation source to solve the problem . But the cottage manufacturers will still be the overall cost in order to solve these parts. ( Such as sales of low-cost display appearance of the material made ​​of metal , which is also without care, the same metal can shield electromagnetic radiation )
Our approach: Although the choice to choose when the monitor heavy weight , but there are cottage within the display with the addition of other insignificant weight , so that consumers can not tell. So the easiest way to purchase a flat hand will monitor ( screen facing up ) , lcd module another person on the phone to the back of the display , such as the signal format becomes less , it indicates that the monitor has a metal shield , and in the work . Of course, this method is somewhat time-consuming, but also need to disassemble , can be considered a very simple way .

Optional TV not just look at the panel

LCD panel LCD monitors can largely determine the brightness , contrast, color , viewing angle , the LCD panel is fast developing part of the LCD panel and LCD monitors are very closely linked, its production , and marketing pros and cons environment and other factors bearing on the quality of the LCD display itself , price and market trends, as an LCD monitor about 80% of its costs are concentrated in the panel, then let consumers buy TV time as long as attention panel everything will be fine yet ?

Let the salesperson at the store in consultation television , they tend to talk about a TV panel with you , usually they will give you about the advantages of television , and then let the other TV and its own TV comparison , another thing to You What indoctrination ; " original screen ,graphic lcd display module the best performance . Which screen with Taiwan , the general quality " sort of argument. So this argument has no real basis for it ? Let 's explore it.

It is understood that compose an LCD TV parts including: LCD panel, backlight control, image processing circuit , the external interface circuit and housing . Certainty on the quality of which play a role in the panel , the backlight and the image processing circuit section tube . A good TV is not a simple superposition of these parts , need to be very careful design and adjustment.

Like " bucket theory ", as affecting the performance of the TV to watch a lot of factors . For example, the number of bit processing circuit , the dynamic picture compensation / optimization technology , a TV signal reception and processing power and so on. Although the lcd module panel on the machine's cost and performance occupy an important position , but if we just blindly pursue this one indicator is advanced , it may fall into one and runs counter to the original intention of the point .

LPL biggest feature on -screen using IPS technology, with high viewing angle , fast response , accurate color reproduction , cheap advantage. The main disadvantage is the poor performance of black , more prone to leakage problems . LPL pixel screen showing a relatively large scale shape. S-LCD LCD panel, belonging PVA (PatternedVerticalAlignment, vertical alignment configuration ) VA technical areas , is the successor of MVA technology and developers . And its overall performance has not lag behind the latter , has a wide viewing angle and fast response time , pixel is scaly , but more than the shape of LPL much smaller scale .

LCD splicing screen "war " LED display

Customers often consult the difference between lcd and led , LCD splicing screen with LED display which is better ? Here a more comprehensive explanation of the difference between the next lcd and led in the end is what ? LCD splicing screen with LED display characteristics and main applications in what place ? led and lcd difference really so great?

I. What is LCD? What is the lcd module splicing screen ?

LCD stands for liquid crystal displays. LiquidCrystalDisplay , mainly TFT, UFB, TFD, STN LCD and other types of procedure entry point could not be located in the dynamic link library .

LCD splicing screen with LCD display unit splicing of the way through splicing control software system , to achieve the effect of a large-screen display splicing screen body . There are now common splicing 5.3MM 55-inch ultra-narrow LCD splicing , 6.7MM 46-inch Ultra Narrow mini lcd module splicing screen , 47 -inch LCD stitching, 60 inch and 40 inch LCD Video Wall Narrow LCD splicing system .

Second, what is LED? What is a LED display ?

LED is the acronym for Light Emitting Diode LightEmittingDiode . LED applications can be divided into two categories: one LED display ; Second, single-tube LED applications, including backlight LED, infrared LED and so on . LED display now , China's basic design and production technology level and international synchronization. LED display is formed by light-emitting diodes arranged in a display device 5000 yuan a single computer configuration . It uses low- voltage scan driver with : low power consumption , long life , low cost , high brightness , less failure, large visual distance and other characteristics .

Look at the LCD panel

IPS Panel : IPS panels are the advantages of high viewing angle , fast response , accurate color reproduction , the LCD panel of high-end products . The display panel technology enhances the dynamic display , watching sporting events, action movies and other sports program is faster to get a better picture quality. Carefully look at the screen ,16x2 lcd display if you see is the direction toward the left scaly pixels , plus hard screen , then you can determine the IPS panel .
PLS panel: Currently advertised professional screen IPS display viewing angle can reach 178 degrees , according SMD introduced the newly developed Super PLS screen viewing angle has been significantly improved once again , doubling compared to IPS . Not only is the viewing angle has increased substantially, new LCD screen brightness increased by 10% compared to IPS ; By eliminating the need to use a polarizer and other expensive parts, the production cost of the LCD screen is also reduced by 15% .
MVA panel : MVA panels are now used more high-end LCD panel type , belonging wide viewing angle panel . MVA It is the use of the LCD at rest is not a traditional tower , but a biased point of rest ; when voltage is applied to the liquid crystal molecules changed to allow the backlight level much more quickly through , so that we can significantly shorten the display time , but also because of changes to the LCD 20ms or less. Molecular alignment , allowing wider viewing angle . On the increase in the angle up to 160 degrees.
TN panel : TN panel in addition to a relatively low cost , but also has a more rapid response time , which is only from the performance parameters can be seen : a lot of TN liquid crystal display panel after the overdrive , its value can be achieved 2ms or 1ms, which for gaming enthusiasts, the response time is a very important indicator , 128x64 oled this is the advantage of being TN panels can not be replaced .
Before the mainstream market, the LCD panel display with a wide range of products available at present wide viewing angle , the conventional TN panels still still play it to the heat. The design and function of these panels there is a very big difference , reflecting the display industry step by step development of the track. Combinations between different panels created a monitor has different strengths and advantages , the difference of expression to give consumers more choices.

Nonlinear distortion of the video signal

Signal distortion caused in the transmission signal itself to be transmitted related to the amplitude ,20x4 lcd display this distortion , said nonlinear distortion between the input signal the output is not a simple linear relationship. Equation : U2 = K (U1) U1, the transfer function K (U1) is not only a function of frequency or time , and is a function of the input signal .
Nonlinear distortion caused by the nonlinear components , and their effect on the parameters with which the signal level is changed ( by the size of the impact signal level ) . Transmission system nonlinear dynamic range and signal related to a wide range of distortion from the signal components can be divided into the following:
· Luminance signal nonlinear distortion
· Chroma gain nonlinear distortion
· Chroma phase nonlinear distortion
· Chromaticity ,lcm module luminance intermodulation distortion
· Differential gain
· Differential phase distortion
And synchronization signal static nonlinear distortion
· Synchronous signal dynamic nonlinear distortion
6 line time waveform distortion
Reflecting the line frequency to 500KHz IF distortion , on behalf of the larger size of the image content changes in brightness in the horizontal direction , frequency distortion will cause the image horizontally ill , causing severe horizontal tail, somewhat similar to the RGBHV signals "LF response bad "fault.

Soft edge fusion splicing system

TFT-LCDCELL process diagrams

TFT-LCDCell manufacturing process of the array after the process, which is based on the Array front glass substrate, a glass substrate and color filter combined and inserted between the two glass substrates a liquid crystal (LC). Main processes include: cleaning, orientation film coated PI layer, friction orientation, printed plastic frame and pad printing Silver Point spray powder, assembly, cutting & lobes, filling liquid crystal detection.

First, the substrate using the lotion, brush, Character LCD Module ultrasound, IR, UV and other devices, the above remove particulates and oil, in order to ensure the cleanliness of the substrate condition.

That has formed on the substrate layer washed 500Ao ~ 1200Ao (0.05μm ~ 0.12μm) PI films uniform. By rubbing the alignment grooves on the PI film manufacturing orientation of the liquid crystal sequentially ordered.

After using the screen printing method, will be required to transfer to the CF frame plastic substrate to provide CF / ITO substrate is then necessary to make the Edge with plastic box. The agent is spread evenly spaced on the substrate for maintaining uniform spacing between the upper and lower substrates.

Antistatic agent in the world will have a wide range of applications

Antistatic agent market in North America is expected to 2004 years ago, the average annual growth rate of about 4%, to use point of view, most of the use of electronic appliances and on food packaging materials. The terms of the types from the antistatic agent, ethylamine class multi-use polyolefin, as electronic equipment packaging; while quaternary ammonium compounds are often used in PVC, such as industrial conveyor belts, disk packaging and bottles, etc.; fatty acid esters are more use of internal antistatic polyolefin use. European antistatic agent market will have an estimated annual growth rate of 2.5%, on purpose, mainly used in polystyrene, ABS and other styrenic polymer processing, due to add antistatic agent usually has a lubricating efficacy, it is sometimes difficult to distinguish with a lubricant. In Japan, an antistatic agent mainly of 0.1% to 0.2% of the concentration of mixed plastic being, as accurate as the mixing amount of the product on the type of polymer, wherein the polypropylene is the most frequently used products antistatic agent , followed by PVC and ABS. Antistatic agents throughout the Japanese usage rate is expected in 2003 nonionic / cationic antistatic agent used about 5,000 tons, the future will also be about 1% growth rate continues to grow.

The terms of the types of antistatic agents, polymer-type antistatic agent is the most promising permanent products, particularly the use in precision machinery is the growth of popular expectations. This is due to household appliances, electronic equipment used by the electronic circuit, when the electrostatic accumulation is excessive, Character LCD Modules poor contact may occur the situation, hence, have to prevent excessive accumulation of static electricity in this high-performance anti-
Static agent needs to be quite optimistic about the future. But so far the use of more surfactant adsorbed on the plastic surface moisture in the air to produce the effect of preventing static electricity, but because of vaporization, surface cleaning and other reasons, often making antistatic effect disappears or is contaminated, then the high dependence on humidity, in the case of drying effect is poor, so non-surfactant polymer products become better product.

Molding a polymeric antistatic agent is dispersed in the resin play a fixed effect, OLED Display and the low-molecular type (surfactant system), compared, and show a direct effect after molding, is not volatile, will not be affected by exposure contamination after cleaning effect is not reduced, etc., but the drawback is that only low-molecular type antistatic agent than the added quantity.

Currently polymeric permanent antistatic agent, compared with a surfactant system, it is still high-priced products, the manufacturers themselves without a permanent antistatic agent technology, inevitable costs will be relatively enhanced. At present, because of both the price, there are still considerable differences, there is currently a permanent antistatic agent penetration is still low, but the future along with the IT market needs and future expansion of the market, as well as other incentives under falling prices, have helped in the product market expansion.

Dot-matrix graphic LCD module

This module is a module matrix, which matrix is ​​characterized by continuous pixels arranged in rows and columns are not arranged in an empty compartment. So you can show a continuous, full graphics. Since it is also a XY matrix pixel composition, so in addition to display graphics, but also can display characters.

1 row, column-driven
This is a dedicated controller to the external module, which module is only fitted with a common row, column drivers, which drive the pixel is actually only a general drive output terminal, and the input terminal to only four data input of the following , shift signal input terminal, the latch input terminal, the AC signal input terminal, etc., such as HD44100, IID66100 so on. Such modules must be an external control circuit, such as HD61830, SEDl330 etc. can connect with computer. The largest number of species of the module, the most common. Although the need to use self-made controller, but it also gives customers left a different controller can choose freely.

2 rows, columns driver - controlled
This is a direct interface with the computer, the computer directly controls the drive depend on the module. Such modules used in the column driver with I / O bus data interface module can be directly linked to the computer's bus, eliminating the need for dedicated controller, so the whole system cost reduction benefits. For the small number of pixels, the machine features small, for computer software programming and very familiar user very suitable. But it will take some of the resources on your system.

3 rows, columns, control type
This is a built-in controller type dot matrix graphics module. Also the more popular type. This module is equipped with not only the first category, such as row and column drivers, but also like the T6963C assembly of dedicated controller. This controller is a liquid crystal driver and a computer interface, which in the most simple way controlled by the computer, the computer receives a variety of information and feedback, through their independent information processing to achieve the display buffer management, well provided to the driver needs of the various signals, pulse, manipulate the lcm module of the drive to implement the module function. This controller has its own set of special instructions, and have their own character generator CGROM. Users must be familiar with the detailed specification of this controller can be summarized as. This module allows users to get rid of the controller design, processing, production and other series of work, and also allows the computer to avoid the cumbersome controls on the monitor, saving.

Liquid crystal sealing material plastic box introductory knowledge

Currently used on the lcd module frame plastic sealing material that there are two main categories, one box is UV curable adhesive, mainly used in the production of pieces of sheet curing methods on; other is thermally cured sealant, most Semi-automatic production line is mainly use this plastic box. The following description is represented by XN-5A thermosetting plastic box.
XN-5A used in the liquid crystal display industry has thirty years of history, and almost monopolized the LCD monitor sealing material nearly twenty years later with the development of large-size TFT, was the constant application of new materials to break . Even now, XN-5A the lcm module industry is still the most important sealing material.
XN-5A sample is tested thousands of times before they succeed in an electronic packaging materials, its unique three-component liquid mixed party and the resulting formation of three segments curing methods, packaging materials completely avoid contamination of the final product , is the last century's most successful electronic packaging materials.
XN-5A epoxy resin, catalyst and solvent mixture from the catalyst. Room temperature, the plastic box in the epoxy resin in liquid form, the catalyst is dissolved in a liquid solvent inside the uncured plastic boxes have a certain viscosity, but with continued stirring viscosity fall within a range. Inside the catalyst solvent evaporation starts at 80 degrees, but to evaporate completely, they should at 105 degrees, the temperature of the catalyst can be avoided during solvent evaporation absorb moisture; losing solvent crystallization catalyst will become crystal. Then it can be combined support from the upper and lower liquid crystal substrate can be reduced when heated plastic box behind the space inside the powder kept under pressure and do not deserve to make room for a long time after the softening powder in the heating kept under pressure to produce permanent deformation, thus changing the setting parameters of the liquid crystal cell gap. Melted at about 1180C liquid catalyst, as the temperature rises, the molecular dispersion of the epoxy group which, when heated to about 1420C, the epoxy resin in the catalyst, the high polymerization reaction to form glassy solid, the upper and lower substrates bonded together.
