colour lcd

They have also developed a high-quality STN tranflective colour LCD module using a passive matrix driving method. The problem is that a colour Tsingtek graphic lcd display module screen is effectively three greyscale LCDs stacked on top of eachother, each with it's own colour filter. With this in mind, the industrial designer at IntelliDesign urged us to find a small, high resolution colour Serial Lcd Display Module screen to put into the product. White LEDs are being used in backlight applications for many portable devices that feature small colour LCD screens. 

The difference between the polysilicon and amorphous silicon LCD module lcm low

lcm LCD module amorphous silicon (a-Si TFT) the difference between low-temperature polysilicon (LTPS TFT) is Low-temperature polysilicon LTPS Low Temperature Ploy Silicon is an abbreviation , generally OLED Display low-temperature polysilicon manufacturing process temperature should be below 600 degrees Celsius ,especially for the manufacture of a-Si LTPS different from the manufacturing process , " laser annealing " (laser anneal) requires even more . Compared graphic lcd modules with a-Si, LTPS electrons move faster than the a-Si 100 times faster , this feature can be explained by two issues: First, each LTPS faster than the a-Si PANEL PANEL reaction rate ; secondly , lcm module LTPS PANEL appearance size smaller than the a-Si PANEL . Here are the LTPS and a-Si compared held significant advantages:

 1 , the driving IC to the peripheral circuits are integrated on the panel substrate more feasible ;
 2 , faster response , the appearance of smaller, less coupling and components ;
 3 , panel system design easier ;
 4 , the stability of the panel stronger ;
 5 , the higher the resolution

LCD modules and maintenance methods

before or after disconnecting the signal level , there may be damage to the module IC and circuit , should drive power, the logic of power , it helps to maintain a good display screen and avoid the power off when the voltage of impact damage. It is recommended to use as a drive with controlled power supply module .low temperature lcd module will not allow the outer lead wrong, when you want to debug lcm module module , please note the correct wiring, especially the positive and negative power supply wiring can not be wrong, or they may cause overcurrent, overvoltage, burned on the circuit chips and other components for LCD module appear damaged .

Common digital display LCD module are as follows

Common digital display LCD module are as follows
1. Counting module, which is a different digit seven-segment type lcd module and decoding drive, or plus the counter assembly into the count display unit. It has a record, process, display digital functions.
2. Metering module, a metering module has a number of segment-type liquid crystal display device having decoding, driving, count, the integrated circuit chip A / D conversion of the assembled module. Since the IC used having A / D conversion function, so the analog electrical signal may be input into a digital quantity is displayed.
3. Timing module, timing module for liquid crystal display device timing longest history, a liquid crystal display device with a timer integrated circuit assembly together is a fully functional timer. It does not sound in the finished watches shell, so called timing module.Generally used mini lcd module.

How TFT works

Display any color can be issued by a number of light pixels, each pixel display as long as the control corresponding color can achieve their goals. TFT LCD displays backlight technology in general use, in order to precisely control each pixel of color and brightness you need to install a similar switch shutters after each pixel, when the "blinds" Open the light can come through, while "blinds "light can not pass through to the rear off. Of course, technically it would not actually realize just say so simple. lcd module (Liquid Crystal Display) is the use of liquid crystal properties (when heated liquid, will crystallize when cooled to a solid state), generally there are three crystal forms: smectic similar clay (Smectic) liquid crystal, similar matchstick thin filaments (Nematic) liquid crystal, and similar cholesterol-like (Cholestic) LCD.

How to achieve LCD Display is working at low temperatures

Achieve a liquid crystal display using an external heater work at low temperatures, compared with the built-in heating and increasing the drive voltage method, this method is simple, without the liquid crystal display to be demolished, to improve the reliability of the display, you can achieve a liquid crystal display in the low temperature range. Working in very low temperatures in liquid crystal display range we call low temperature lcd display. When the ambient temperature change can automatically control the display box, no manual control, environmental adaptability. In the case of -40 ℃, when the heater heating voltage is + 20V, simply heating a lcd modules 6 to 8 minutes to work properly. If + 12V heating, the heating is working properly monitor, the average power of the heater temperature by the external environment, the lower the temperature for 15 minutes, then the greater function average heating power.

TFT LCD displays and monitors What is the difference

lcd module (LCD) English called Liquid Crystal Display, TFT LCD is to use TFT (Thin Film Transistor) liquid crystal display manufacturing. TFT is a thin film transistor active matrix liquid crystal display device. TFT LCD Display is designed at each pixel of a FET switch, so it is easy to achieve true color, high-resolution liquid crystal display device. LCD flat panel displays, particularly TFT-LCD, is at this stage only comprehensive catch up and surpass CRT display device in brightness, contrast, power, life, size and weight overall performance, its excellent performance, good mass production characteristics high degree of automation, low raw material costs, broad space for development, the new century will quickly become a mainstream product, it is a bright spot in the 21st century, global economic growth.

Thin Film Transistor

TFT (Thin Film Transistor) that is a thin film field-effect transistor. The so called thin-film transistor, liquid crystal means that each pixel on the lcd module are made in the subsequent thin film transistor integrated to drive. Which can achieve high-speed, high-brightness, high-contrast display screen information. TFT active matrix liquid crystal display belong. TFT LCD display is characterized by good brightness, high contrast, strong sense of hierarchy, bright colors, but there are relatively high power consumption and costs less. TFT LCD technology to accelerate the development of mobile phone color screens.
