touch screen interactive vending machine.Its structure consists of two highly transparent conductive layers, usually the lower layer is ITO glass (commonly referred to as ITOGlass), and the upper layer is ITO thin film material (commonly referred to as ITOFilm), which are separated by fine insulation points in the middle. At present, there are products on the market that use ITO glass or other transparent ITO materials on both sides. When there is no pressure on the surface of the touch screen, the upper and lower layers become insulated; once pressure is applied to the touch screen, the upper and lower circuits are conducted. At this time, the controller applies driving voltages in the X-coordinate direction and the Y-coordinate direction to detect the XY coordinates of the contacts, thereby clarifying the positions of the contacts. The upper and lower layers of the resistive touch screen are sealed by bonding. The signal is generated in the middle of the sandwich, so it can be protected from dust, water and dirt, and has good performance. At present, the manufacturing technology of resistive touch screens has also made great progress. The large-scale production process has been generally used. The batch consistency of products has obvious advantages in various touch screens. This is also the fact that resistive touch screens can meet large quantities. Important reasons for supporting products. The technical principle of the resistive touch screen will be explained in detail in the text of the next section.
