dell touch screen monitor 55 inch

dell touch screen monitor 55 inch.Its structure is the simplest . It is coated with a transparent oxide and metal conductor layer in the double laminated glass immediately in front of the display screen , and four electrodes are drawn from the four corners under the control of the controller . Through the lead , there is high-frequency current in the sandwich conductor Flow ( as shown in Figure 5). Due to the presence of the human body's electric field , the touch point finger and the inner coating of the screen form a tiny coupling capacitor , and high-frequency current is easy to pass through the small capacitor . In this way , the high-frequency on the symmetrical four electrodes The current is shunted through the small capacitance of the contact . This symmetrical change is detected by the controller . Since the current flowing into the four electrodes is inversely proportional to the distance from the finger contact to the four corners , the coordinate value of the contact can be calculated .
