Ⅰ. Basic content
The 3.97-inch TFT LCD display screen is a liquid crystal display screen that is driven by a TFT (Thin Film Transistor) matrix to display images on the screen. This screen size is 3.97 inches and has the advantages of high definition, high brightness, wide viewing angle and low energy consumption.
The working principle of a TFT LCD display screen is to fill liquid crystal material between two glass substrates, one of which has a color filter and the other has a transistor. When current passes through the transistor, the liquid crystal material deflects, changing the polarization state of the light and thereby changing the brightness of the pixel.
In addition, this screen also has a touch screen function to facilitate user operation and interaction. It is commonly used in various portable devices such as smartphones, tablets, and digital cameras.
