Abstract
A device integrating capacitive touch and resistive touch includes a first sensing layer, a second sensing layer, and a processing unit. The first sensing layer includes a plurality of sensing units, wherein the plurality of sensing units are insulated from each other. The second sensing layer installed below the first sensing layer includes a plurality of electrodes. The processing unit is used for charging the first sensing layer, detecting capacitance variation of the plurality of sensing units, and determining a position of at least one first touch point according to the capacitance variation of the plurality of sensing units in a capacitive touch mode; and charging the first sensing layer, detecting resistance variation of the plurality of electrodes, and determining a position of at least one second touch point according to the resistive variation of the plurality of electrodes in a resistive touch mode.
