smart board 8084i interactive flat panel
smart board 8084i interactive flat panel.When the finger touches the metal layer, the user and the surface of the touch screen form a coupling capacitor due to the electric field of the human body. For high-frequency current, the capacitor is a direct conductor, and the finger sucks a small current from the contact point. This current is discharged from the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The controller obtains a touch by accurately calculating the ratio of the four currents. The location of the point. A schematic diagram of a capacitive touch screen is shown in Figure 1.
