The structure of an LCD liquid crystal display is to place a liquid crystal box between two parallel glass substrates. TFT (thin film transistor) is installed on the lower substrate glass, and a color filter is installed on the upper substrate glass. The rolling direction of the liquid crystal molecules is controlled by the signal and voltage changes on the TFT, and then the goal of flashing is achieved by controlling whether polarized light is emitted from each pixel. At present, there are two main types: LED liquid crystal displays and LCD liquid crystal displays.
LCD is commonly found in electronic consumer products such as televisions, computers, tablets, advertising machines, mobile phones, smart wearables, and smart homes, and is widely present in our daily lives. However, the LCD manufacturing industry has a large initial investment, high entry barriers, and is the upper layer of the supply chain for LCD terminal consumer products, so it is far from the general public, and its processing and manufacturing technology is not well-known to the general public.
In the entire production process of LCD, the dispensing process mainly focuses on the following stages, including liquid crystal, maintenance glue, photosensitive glue/photoresist, UV glue, etc.
Substrate array process:
Glass substrate coated with photoresist/photoresist (4-5 times)
Color film process:
1. Glass substrate coated with black resin light blocking adhesive
2. Apply RGB (red/green/blue) photosensitive layer sequentially to the hollow area of the black light blocking adhesive on the glass substrate
3. After the completion of the four photosensitive adhesive processes, apply the transparent organic maintenance layer photosensitive resin information;
Boxing process:
1. Coating oriented layer thin film
2. Dotting LCD on CF substrate requires high accuracy
3. Spot coating of edge sealing UV adhesive on TFT substrate (about to cut the outer edge scale of the LCD screen)
Module process
1. Point coating of anisotropic conductive adhesive, bonding FPC on LCD panel
2. Apply conductive adhesive to the same points and bond the driver board PCB
3. Plastic frame and module bonding process
