Abstract
A sensing circuit is provided that senses an externally provided pressure on a panel, and includes a sensing capacitor, a first switching element, a second switching element and a third switching element; where the sensing capacitor includes a sensing electrode on the first substrate, the insulating layer and the opposite electrode; the sensing capacitor varies a capacitance based on the externally provided pressure; the first switching element is electrically connected to the sensing electrode to charge the sensing capacitor based on a first switching signal; the second switching element outputs a current based on a second switching signal and a first voltage; the third switching element is electrically connected to the sensing electrode to control the current based on the variation of the capacitance of the sensing capacitor to generate a sensing signal; and where a thickness is decreased, and an image display quality is improved.
