What is the structure of LCD screen?

The inner structure of the liquid crystal display # 5 inch tft lcd display 800x480 display panel # can be divided into two parts, namely the backlight module and the liquid crystal panel # 480x800 tft lcd display 4.3 touch screen 45pin # module. The combination of these two parts each has a role to play. Ordinary liquid crystal displays convert the picture signal into an electronic signal in some way, and then gather these electronic signals on the liquid crystal molecular layer to become corresponding tiny pixels.

Through the above conversion, the corresponding electrons pass through the backlight light, or are in the state of blocking the light. At this time, each pixel can not only express light and dark changes, but also express color images. Coupled with two electronic signals of grayscale and tone, a huge number of LCD panel # 4.3 tft lcd screen 480x272 HD Touchscreen Module # pixel groups will be formed to form the picture in the LCD display.

For liquid crystal panels # 7 inch lcd tft monitor #, there is a color filter substrate module, which mainly includes polarizers, color filters, common electrodes and transparent conductive films; there is also a pixel drive substrate module, which is composed of polarizers Plate, thin film transistor, pixel electrode, transparent conductive film and guide film are composed of several parts. It can be said that these two glass substrate components form a system by adding and sealing liquid crystal molecular layers among them # lcd touch tft 3.5 #.

The installation position of the color filter substrate assembly is on the top, and its composition is completely composed of related polarizers, color filter film layers # tft lcd module # and transparent conductive films on the glass substrate. We will also make an alignment film on the transparent conductive film. The corresponding component of the relevant pixel driving side substrate below is composed of a polarizer mounted on a glass substrate and a transparent conductive film. The guide film is also made on the transparent conductive film.

In addition, the backlight source of the LCD screen # 7 inch capacitive touch screen tft lcd display # uses the LED light source, plus the diffusion sheet and the diffusion plate to form a modular construction system. The liquid crystal display outputs corresponding images completely through the liquid crystal # 3.5 inch 320*480 tft lcd display with ili9488 # panel module. The electronic circuit control module related to the conversion of the liquid crystal display # 4.3 tft lcd # into the electronic number, and then the related control liquid crystal panel# 1.44 tft lcd # module is completely shielded from the light emitted by the backlight light source module.
