Is touch and display different?

The LCD is the inner layer of the screen, which is responsible for displaying images; the touch screen is the outer layer, which is responsible for precise positioning. The functions of the two are completely different, but they are generally integrated. That is to say, the screen is divided into at least two parts: the display part and the touch part. There are many categories of display technologies, such as TFT, AMOLED, etc. Touch technology is mainly divided into resistive type and capacitive type.
