Production Equipment Scale

TFT LCD display is a widely used display technology in modern electronic devices, which offers high definition, fast response time, and low power consumption. To produce TFT LCD displays, highly precise production equipment and complex manufacturing processes are required. Therefore, TFT LCD factories usually have advanced equipment and technology to ensure high-quality and high output. These factories involve multiple production steps, including cleaning, cutting, and coating of glass substrates, deposition, photolithography, and etching of thin films, and utilize automated control systems to ensure production stability and consistency.

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.
