More Information
Summary:A touch display device comprises a display panel including a plurality of touch electrodes, and a plurality of touch lines; a touch sensing circuit configured to generate a digital touch sensing output signal by accumulating touch sensing signals transmitted from the plurality of touch electrodes through the plurality of touch lines; and a touch controller configured to control a amplification gain of the touch sensing circuit by extracting a plurality of single touch sensing data having touch peak values from the digital touch sensing output signal and by comparing a distance of touch peak values between adjacent single touch sensing data to a predetermined reference distance.
