Most of the existing liquid crystal displays in the market are backlight liquid crystal displays (lcds), which include a liquid crystal display panel and a backlight module (backlight module). The liquid crystal display panel operates on the principle that liquid crystal molecules are poured between a thin film Transistor Array (TFT Array Substrate) and a color filter (color filter, CF) Substrate, pixel voltage and common voltage are applied to the two substrates, and the rotation direction of the liquid crystal molecules is controlled by an electric field formed between the pixel voltage and the common voltage, so that light of a backlight module is transmitted out to generate a picture. The liquid crystal display panel forming process generally includes: front Array (Array) process (thin film, yellow light, etching and stripping), middle Cell (TFT substrate and CF substrate) process and back module assembly process (driver IC and printed circuit board pressing). Wherein, the front-stage Array process mainly forms a TFT substrate to control the movement of liquid crystal molecules; the middle Cell process is mainly to add liquid crystal between the TFT substrate and the CF substrate; the back module assembly process mainly drives the integration of IC pressing and printed circuit board, and further drives the liquid crystal molecules to rotate and display images.
