What is the difference between a capacitive touch screen and a TFT mobile phone LCD screen--LCD screen manufacturers Capacitive screen and resistive screen refer to the transparent and very thin touch film on the surface of the LCD screen of the mobile phone. If that layer of film belongs to the capacitive touch layer, then such an LCD screen is called a capacitive screen; otherwise it is called a resistive screen; the same LCD screen can be made into a capacitive screen or a resistive screen. So what is the difference between a capacitive touch screen and a TFT LCD screen? A capacitive touch screen is not a real screen, but a component that is installed above the LCD screen. The capacitive screen is a piece of transparent tempered glass in appearance. Furthermore, the two cannot be compared horizontally, because they are not the same type of parts. Most mobile phones have both types of screens. Capacitive touch screen is a kind of touch screen, it is transparent like glass, does not display any content and does not emit light, its function is to sense the user's touch operation. The TFT screen is the real screen. TFT is the most widely used LCD screenmaterial. It is mainly used in the low-end display field, and it is widely used in mobile phones. TFT LCD screen is thin film transistor LCD screen, it is a kind of display screen, it does not have the function of sensing touch, it can only be used to display images. In the current mobile phones, these two screens are usually used at the same time. The two screens are overlapped together. The TFT LCD screen is responsible for displaying images, while the capacitive LCD screen is responsible for sensing user operations. This is the 'inner screen' and 'outer screen'.
