Abstract
A touch and gesture sensing system and a driving method thereof are provided. The touch and gesture sensing system comprises: a display panel comprising a pixel array, sensors, and sensor lines connected to the sensors; a display driving circuit that writes a data voltage to the pixels of the pixel array during a display driving period; and a sensor driving circuit that applies a touch sensor driving signal to the sensors to sense touch input during a touch sensing period and applies a gesture sensor driving signal to the sensors to sense gesture input during a gesture sensing period.
Claims10
A touch and gesture sensing system comprising:
- a display panel comprising a pixel array, sensors, and sensor lines connected to the sensors;
- a display driving circuit that writes a data voltage to the pixels of the pixel array during a display driving period;
- and
- a sensor driving circuit that applies a touch sensor driving signal to the sensors to sense touch input during a touch sensing period and applies a gesture sensor driving signal to the sensors to sense gesture input during a gesture sensing period.
A driving method of a touch and gesture sensing system, the method comprising:
- writing a data voltage to pixels of a pixel array during a display driving period;
- applying a touch sensor driving signal to sensors to sense touch input during a touch sensing period;
- and
- applying a gesture sensor driving signal to the sensors to sense gesture input during a gesture sensing period,
- wherein the gesture sensing period is allocated in the remaining part of one frame period, except the display driving period and touch sensing period.
