Production Process
The production process of TFT LCD involves multiple steps, including substrate cleaning and cutting, coating, film deposition, photolithography, and etching. First, glass substrates are cleaned and cut into specific sizes. Then, a layer of transparent conductive material is coated onto the substrate surface. This is followed by deposition of several thin films, including the active layer, metal layer, and passivation layer, using specialized equipment. Photolithography and etching processes are then used to create the desired patterns on the different layers.
Finally, the substrates are assembled into a complete TFT LCD panel, including the addition of polarizer, backlight unit, and driver IC. The entire production process is highly precise and requires advanced equipment and technology to ensure high-quality and high-yield production.
