Patent ID: 10528179

Abstract:
The present disclosure provides a touch sensing system and a display device including the same. The touch sensing system includes: a touch screen that includes a plurality of first driving electrodes, a plurality of second driving electrodes, and a plurality of sensing electrodes; a first driving circuit that outputs a first driving signal of a pulse waveform to a respective first driving electrode of the plurality of first driving electrodes in a first sensing period; a second driving circuit that outputs a second driving signal of a frequency sweep waveform to a respective second driving electrode of the plurality of second driving electrodes in a second sensing period; a first detection circuit that detects a first sensing signal sensed by at least one of the sensing electrodes in the first sensing period; a second detection circuit that detects a second sensing signal sensed by at least one of the sensing electrodes in the second sensing period; and an inductor that is connected between the sensing electrodes and the second detection circuit in the second sensing period.
