touchscreen interactive intelligent display panels.(6) Projected capacitance type : Projected capacitance is different from surface type , mainly because the surface uses upper and lower electrodes as capacitors , while projection type divides the upper and lower electrodes into a matrix distribution to draw the X- axis and Y- axis cross distribution. It is a capacitance matrix . When the finger touches, the X and Y axes can be used to detect the capacitance change at the touch position , and then calculate the position of the finger. Apple Computer (Apple) of the i Phone that is based on this technology , its high technical threshold, but the market outlook can be expected.
