The PP846 3BSE042238R1 touch screen, also known as the “touch screen” or “touch panel,” is an inductive liquid crystal display device that can receive input signals such as contacts. When touching graphic buttons on the screen, the touch feedback system on the screen can drive various connection devices according to pre programmed programs, which can replace mechanical button panels and create dynamic audio and video effects through the liquid crystal display screen.
Touch screen technology is the most easily accepted computer input method for ordinary people after keyboard, mouse, handwriting pad, and voice input. By utilizing this technology, users can easily operate the host by lightly touching the symbols or text on the computer screen with their fingers, making human-computer interaction more straightforward. This technology greatly facilitates users, and the PP846 3BSE042238R1 is an attractive new multimedia interactive device. The essence of a touch screen is a sensor, which consists of a touch detection component and a touch screen controller. The touch detection component is installed in front of the display screen to detect the user’s touch position and receive and send the touch screen controller; The main function of the touch screen controller is to receive touch information from the touch point detection device and convert it into contact coordinates to send to the CPU. PP846 3BSE042238R1 can also receive commands from the CPU and execute them
