The connection and difference between touch screen and monitor

1. The touch screen is referred to as TP, which is generally used to respond to human touch events

2. The display screen is generally used for display, commonly used are LCD, OLED and so on.

3. The touch screen and display screen in the mobile phone are made together. It looks like the screen is both a touchscreen and a display, but it's not. The mobile phone screen is generally made of two layers, the upper layer (outer layer) is a touch screen, used for touch, and is generally transparent, requiring good light transmission; the lower layer (inner layer) is a display screen, used for display.
To sum up, the image we usually see is displayed on the inner display screen, but it is only seen through the touch screen.

Note:

1) There are two types of touch screens: resistive and capacitive. The relationship between touch screen and people is very close, and capacitive touch screen is commonly used now.

2) Application fields of touch screen: mobile phone, (tablet) computer, etc.
