dell interactive touch display.When a person is not in contact with the touch panel, the various electrodes (Electrode) are at the same potential, and the touch panel does not pass through the ELECTRIC Current . When in contact with the touch panel, the static electricity in the human body flows into the ground to generate a weak current. The detection electrode changes the current value to calculate the contact position. The antimony tin oxide film (ATO) layer on the glass surface has a resistivity. In order to obtain the same electric field, electrodes are installed on its periphery, and current is input from four sides or four corners.
