DISPLAY DEVICE WITH TOUCH SENSOR, POTENTIAL CONTROL METHOD AND PROGRAM
First Claim
1. A display device with a touch sensor comprising:
- a plurality of pixel electrodes having TFT circuits;
a common electrode arranged opposite to the pixel electrodes;
a display function layer having an image display function;
a display control circuit performing image display control so as to fulfill the display function of the display function layer by applying a voltage for display between the pixel electrodes and the common electrode based on an image signal;
a touch detection electrode provided opposite to the common electrode and forming capacitance between the touch detection electrode and the common electrode; and
a gate buffer coupled with gates of the TFT circuits through each of gate lines,wherein the gate buffer is switched to be coupled with one of a first-L line and a first-H line through a first switch, andwherein the gate buffer is coupled with a second line.

Abstract
A display device with a touch sensor includes: plural display pixel electrodes; a common electrode arranged opposite to the display pixel electrodes; a display function layer having an image display function; a display control circuit performing image display control so as to fulfill the display function of the display function layer by applying a voltage for display between the display pixel electrodes and the common electrode based on an image signal; and a touch detection electrode provided opposite to the common electrode and forming capacitance between the touch detection electrode and the common electrode, wherein a drive voltage for display applied to the common electrode by the display control circuit is used as a drive signal for the touch sensor, and a gate potential of TFT circuits included in the display pixel electrodes is increased during a period when the drive signal for the touch sensor is applied.
