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 .

How to identify the original color TV

As living standards improve, everyone on the brand and quality appliances are increasingly critical, while imports of household electrical appliances will naturally be more popular. But in the purchase process, consumers are buying is difficult to clearly identify whether imported appliances is original .TFT LCD Displays By following highlights we will be better able to distinguish whether you purchase home appliances original products .

First , look on the box is printed with the trademark or brand , its upper right corner or small fonts printed on the bottom right corner of the word , and only after the registration of the company recognized the quality of products , the right to use this package , while the cottage or counterfeit there will not be such a logo. Meanwhile, in the electrical back cover will usually be clearly identified producing countries ( such as Japan MadeinJAPAN) or production areas ( such as Hong Kong manufacturing MadeinHongKong), through which identity can be distinguished in the local manufacturing or in the overseas subsidiaries. Some appliances not marked origin, can be checked by using the manual ,COG LCD Module  if the instructions printed on the printing Home location can be determined that the product is assembled in the production .

Second, cottage or counterfeit often use to add, delete , change the way of foreign brands to imitate , and even that is a complete theft trademarks to cheat . At the time of purchase , the consumer must pay attention to the product packaging or instructions on the label which company produced , in order to confirm whether the company's products.

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.

LCD splicing screen routine maintenance of dirt cleaning tips

LCD splicing screen is no longer a luxury few decades ago , along with the popularization of intelligent LCD splicing screen applications are increasingly being used as the LCD splicing technology LCD splicing screen life has also been extended , ordinary LCD splicing screen backlight life of 10,000 to 30,000 hours , while the LCD splicing screen backlight life can reach 5-10 million hours or more , of course, with our daily maintenance is closely Contact our routine maintenance not only the life of the LCD splicing but also has a significant impact on the relationship between LCD splicing screen display effect when used , so the LCD splicing screen for routine maintenance is necessary .
Maintenance of the LCD splicing screen , we have involved in the clean-up of dust , a seemingly simple operation actually there are a lot of tips on cleaning up the dust when the surface of the screen .lcd module First, we can at the screen with mouth blowing gently , gently blow off the dust on the screen . For that part did not blow off the dust , use a dedicated LCD cleaning cloth stitching on the LCD screen gently wipe , wipe when the attention of the force should be small , do not use the screen to rub vigorously . Clean fingerprints on the screen . Clean fingerprints on the screen need to use special screen cleaner and a dedicated LCD cleaning cloth , first we dedicated LCD splicing screen cleaner pour a little to a dedicated LCD cleaning cloth , and then use the dedicated LCD cleaning cloth fingerprint area gently wipe , wipe clean with a dry soft towel to gently wipe the screen clean.
Clean up the oil on the screen . For the need to use alcohol, with a dedicated LCD cleaning cloth stained with a little alcohol , and then gently with oil in the area gently wipe , wipe clean with a dry towel immediately after the wipe clean the screen . Can not dip too much alcohol , alcohol will have a corrosive effect screen , wipe with a towel immediately after going to wipe the screen .
Here we must be reminded that when the Character LCD Modules splicing wall profiles found dirt , put another way to use the correct dirt quit . Use the best media is soft, non-fibrous material , such as cotton , lens tissue or soft cloth , etc., and then stick a small amount of glass cleaner wipe it quietly agent to stop the use of alcohol a class of chemical solution , nor can the rough the cloth or paper goods , since such materials prone to scratches. Here to remind you that , do not spray directly into a clean economy presents on the screen , it is easy to flow inside the screen so that the external LCD screens showing short obstructed, resulting in unnecessary losses.

Chargers and common mode noise

Capacitive touch screen devices is a major problem is that the charger emits high-frequency noise intensity touch performance will decline. Some mobile devices plugged into the charger only provide limited touch capabilities, or connect the charger does not apply when the device can not use the charger display information, in order to cope with high noise charger issue. The best solution to say it is not perfect.graphic lcd display module A quick look online forums and message boards related information, we can find a touchscreen device by charger noise problem is widespread and has made some consumers feel a headache.
Just as a standard USB charging interface rapid promotion in mobile devices, which also spawned a large number of low-cost aftermarket option market charger. Many chargers are more concerned about cost issues, without attention to performance, these chargers using inexpensive components, or the lack of common-mode noise can help reduce specific components.
The power and ground supply voltage with respect to ground voltage fluctuation, but between maintaining the same pressure, it will form a common mode noise. Such fluctuations only in the ground-coupled fingers touch screen that can affect the performance of the touch screen. Finger pressed with the same electric potential, mobile power and ground relative to its volatility will lead to noise injected by a finger touch screen. The amount of charge injected depends on the peak-to-peak voltage of noise.
In addition, the amount of the charge transport is also affected by two factors significantly affect: the fingers and the contact area between the touch screen and the touch screen overlay thickness of the lens.
The higher the capacitance, means injection of the touch screen, the greater the noise. In this case, the capacitance of a parallel plate is formed on one side by the finger contact area, the other side of the reception by the touch screen sensor electrode. First, TFT Display Module with the finger in contact with the touch screen area increases, the capacitance also increases accordingly proportional. However, since the receiving electrode from extremely narrow row or column form, the actual function of the diameter of the fingers.
