Product Details

4 inch capacitive touch screen


The surface capacitive touch screen has a conductive coating on the front surface with wires connected to each corner. A small voltgae is applied to each of these 4 corners. The oparation relies on the capacitance of the human body. When you touch the screen, a small current flow to the point, causing a voltgae drop which is sensed at corners.
