TFT (Thin Film Transistor) LCD (Liquid Crystal Display) screens are a ubiquitous technology found in a wide range of devices, from smartphones and tablets to computer monitors and televisions. This article delves into the world of TFT LCD screen, explaining how they work, their key features, and their applications.
How TFT LCD Screens Work
TFT LCD screens consist of several layers, including a backlight, color filters, a liquid crystal layer, and TFTs (Thin Film Transistors). The backlight provides the light source, which passes through the color filters and liquid crystal layer. The TFTs act as switches, controlling the amount of light that passes through each pixel. By manipulating the orientation of the liquid crystals, TFTs can create images with varying colors and brightness levels.
