The advantages of touch screens

Intuitive interaction: The touch screen provides a direct and natural way to interact with digital content, making it easier for users of all ages to navigate and control.

Multifunctionality: They can be used on various devices and applications, from small smartphones to large interactive displays.

Space saving: As touch screens eliminate the need for separate input devices such as mice or touchpads, they can help design more stylish and compact devices.

Accessibility: Disabled users can use touch screens more conveniently, providing alternative ways to interact with technology.

The basic principle of a touch screen is that when a user touches the touch screen installed at the front end of the display with their fingers or other objects, the touched position (in coordinate form) will be detected by the touch screen controller and sent to the CPU through an interface (such as RS-232 serial port) to determine the input information. The touch screen system mainly includes two parts: a touch screen controller and a touch detection device. The main function of the touch screen controller is to receive touch information from the touch point detection device, convert it into contact coordinates, and send it to the CPU for processing; The touch detection device is installed at the front end of the display, responsible for detecting the user's touch position and transmitting it to the touch screen controller.
