chuangjianxinboke
The touch panel is coated with a layer of tin oxide antimony film (ATO Layer) and a protective film (Hard Coat Layer) on the surface of the transparent glass, and a shielded layer is required between the touch panel and the LCD monitor. The touch panel is a direct embodiment of touch technology, pc panel mini，which is used to sense touch signals and analyze and identify them.
Introduction to Touch Panel Technology The touch panel structure includes three parts: Sensor, Controller and Software. The sensor is the part of the touch panel, which mainly receives the information input through the touch; the function of the controller is to analyze and calculate the position of the contact point, and convert the analog signal into a digital signal, so that the information equipment can receive the input signal; the software part The communication protocol between the connected information processing equipment and the controller allows the information processing equipment to receive and recognize the signal input by the controller for subsequent processing actions.
Touch panels can be divided into resistive, capacitive, optical, and sonic types according to different sensing technologies. The principles and characteristics of each technology are introduced below.
