It plays an important role lcd display in the rotating buffer memory

 Two types of motor failure by rotating crane crane pictures, directional control valves, brake valve, relief valve, overload, find fault, it needs to investigate the hydraulic system diagram gradual effect of combining different parts. Examination found that Lcd display modules the rotating motor is working properly, no abnormal sound or heat, can be reversed, analysts believe that is good. When the rotary directional control valve, the pressure valve is a check valve to the left to the right side of the rotating motor through the opening stroke, the left and right side is normal. Check the pressure gauge, the working pressure is normal  work and no vibration and noise, so that normal rotary valve. Brake brake, parking Serial display modules can be stopped, brake, and has nothing to do brake. In the inspection found no problems, and finally check the battery. It plays an important role in the rotating buffer memory. Cranes and hydraulic accumulators and batteries, has two main functions, the first time the engine is running at high speed within a short period of time, the energy storage device, thereby reducing the number of hydraulic pumps, saving engine power.

lcd display the system requires additional configuration

 a highly integrated mixed-signal system-on-chip. It has a 100-pin TQFP package, low power supply voltage of 2.7 ~ 3.3 V, all I / O, RST, JTAG pins are resistant to 5 V voltage; has high speed pipelined 8051-compatible CIP51 core structure (up to 25 MIPS). The MCU has a total of 64 P0 ~ P7 purpose I / O ports, each port pin can be configured as push-pull output or open-drain output. For VGS12864E, due to its operating voltage is 5 V, and C8051F020 operating voltage is 3.3 V, so Character LCD Modules the output C8051F020 better able to drive 5 V input OLED, the system requires lcd display additional configuration. In addition to the corresponding output port is set to "open drain", but also in the circuit will be connected to each port through a pull-up resistor on a 5 V power supply, so you can ensure C8051F020 logic "1" output can be raised to 5 V. The interface circuit shown in Figure 2.
4 software programming
Software programming language using Keil C51 driver includes a display module hardware (ie write commands and write data), and clear screen display module initialization routines as Serial display modules well as other common Western character display realization process. Since this command system and LCD module drive controller HD61202 compatible, so these lcd display procedures have a high versatility. For character character display, character features of the module library data is prepared in the form of columns of data that a byte of data represents the data of an 8 × 1, and compared with the usual character library, the character is rotated by 90 ° font data. Use Zimo21.exe take matrix software, and set the mode to portrait modulo extraction, you can easily obtain the necessary Western text mode.

the state is set to lcd display show the first two instructions

Instruction modules and LCD driver HD61202 compatible controller, a total of seven instructions. Not described in detail here, as listed in Table 2 only instruction list. Among them, the state is set to show the first two instructions, the rest of the Lcd modules class to read and write commands.VGS12864E interface connection in two ways: one is the direct access mode, the other is indirect access. Either lcd display way you want to access the module must first read the contents of the status register to determine the "busy" flag can be accessed when not busy. Direct access method is a module interface as a memory or I / O devices directly linked to the MCU bus, MCU to access memory or I / O device Serial display modules  the module operation. Indirect access MCU module is operated via software simulation control timing.Write instructions on the display module and write data write operation into the left screen and write the right screen. The difference between writing about half the screen is only set corresponding chip select signals, and the difference between writing instruction and writing data when the write data is set RS register select signal. Initialization operation is completed and opened to determine the display position of the display.

lcd display congealing used to improve security and reliability

In terms of performance, TFD both the TFT LCD liquid crystal screen and the advantages of the lcd display  screen, TFD LCD is higher than the STN LCD screen brightness, and color is more bright-coloured, more power saving than TFT LCD screen at the same time, but in the color and brightness is worse than TFT LCD.
As TFT technology maturity in the COG LCD Display early ninety s, color LCD flat panel display is developing rapidly, less than 10 years, rapid growth TFT - LCD display for the mainstream, and it has the advantage of this is inseparable. The main features are:
(1) use good features: low voltage application, low driving voltage, congealing used to improve security and reliability; Flat, thin, save a large amount of raw materials and the use of space; Low power consumption, its power consumption is about one over ten of the CRT display, reflection type TFT - only about one percent of the Character LCD Modules lcd display and even save a large amount of energy; TFT - LCD products and specifications, size series, species diversity, convenient and flexible to operate, easy to maintenance, updates, upgrades, long service life and many other features. Display range covered the range from 1 inch to 40 inches all the display and the application scope of the projection plane, is a full size display terminal; Display quality from the simplest monochromatic character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of various types of video display; Display mode has a look, projection, type of perspective, there is also a reflection.

Since this command system and lcd display drive controller compatible

Software programming language using Keil C51 driver includes a display module hardware (ie write commands and write data), and clear screen display module initialization routines as well as other common Western character display realization process. Since this command system and lcd display
 drive controller  compatible, so these procedures have a high versatility. For character character display COG LCD Displaycharacter features of the module library data is prepared in the form of columns of data that a byte of data represents the data of an 8 × 1, and compared with the usual character library, the character is rotated by 90 ° font data. Use Zimo21.exe take matrix software, and set the mode to portrait modulo Coding System lcd module extraction, you can easily obtain the necessary Western text mode. Since each column of data to the display module 8 × 1 is the low front, high in the post, in order to further achieve the correct display of Chinese and Western culture, the need for each byte matrix obtained by the above method to conduct a swap of high and low , the program uses an array UpsetChar  to achieve. Western character used in the program is 16 × 8 dot matrix, character is a 16 × 16 dot matrix.

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 .
