TFT Display uses an image converter composed of ultra-thin thin film transistors. Under the illumination of a backlight, by controlling the switching state of the thin film transistors, the arrangement direction of the liquid crystal molecules changes, thereby controlling the transmission and reflection of light, presenting out image. TFT screens are widely used in electronic products, such as mobile phones and images. TFT screens are widely used in electronic products, such as mobile phones, e-books, tablets, game consoles, etc. Its advantages are high brightness, rich colors, and clear images. It can display high-quality videos, pictures, text, etc., and at the same time, it has a wide viewing angle and good visual effects. In addition, TFT screens also have the characteristics of low power, long life, and anti-interference, and are widely used in various electronic products.
