What technology is touch screen?

Touch screen technology is a new input mode of human-computer interaction. Compared with the traditional keyboard and mouse input method, touch screen input is more intuitive. Through the recognition software, the touch screen can also realize handwriting input. The touch screen consists of a detection component installed in front of the display screen and a touch screen controller. When fingers or other objects touch the touch screen installed in front of the display, the touch position is detected by the touch screen controller and sent to the host through interfaces (such as RS-232 serial port, USB, etc.). ). At present, the touch screen has developed from a single touch screen to multiple touch screens.
