A touch sensing device is connected to a plurality of touch sensors to drive the plurality of touch sensors and to receive a sensing signal. The touch sensing device includes an input unit generating pieces of sensing data by using a sensing signal input from each of the plurality of touch sensors and a correction unit dividing the pieces of sensing data into a plurality of groups and applying different correction values to the sensing data of each of the plurality of groups to generate correction data.

Touch sensing device having group correction unit and driving method thereof

The present disclosure discloses a touch sensing signal processing circuit which senses a change in capacitance of a sensing node for touch sensing and provides a logic signal corresponding to the touch sensing. The touch sensing signal processing circuit of the present disclosure is configured using a delta-sigma analog to digital converter. Auto-tuning may be performed by delta-sigma analog conversion.

Touch sensing signal processing circuit

The present disclosure provides a display device configured to float a display electrode coupled to a touch sensor by a parasitic capacitance when a downlink signal is received from a touch pen to the touch sensor.
