What is touch screen and display?

The touch screen is an ordinary touch screen. It has no image display function. It is completely transparent and looks like a piece of glass. Nano Blackboard's touch screen all-in-one machine can choose to match the touch screen. There are infrared touch screens, capacitive touch screens, and nano-film touch screens; and The display screen (the LED display liquid crystal panel used with the touch screen, generally a liquid crystal screen, that is, LED and LCD) is used to display screen images and cannot perceive touch. It can also be called a touch display screen. 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.
All In One Smartboard has a more user-friendly five-finger screen design, which can realize the interactive operation between traditional chalk writing and display. Wall Mount Touch Screen adopts professional touch technology, which can satisfy multiple people's simultaneous touch operation.
