Abstract
A display device includes a display unit including a plurality of pixels connected to an initialization line and a first power source line, a sensor unit provided on the display unit and including a plurality of driving electrodes, a sensor driver providing a touch driving voltage to a plurality of driving lines connected to the plurality of driving electrodes, a power supply providing an initialization voltage to the initialization line and providing a first power source voltage to the first power source line, and a compensation circuit compensating for the initialization voltage.
Claims16
A display device comprising:
- a display unit including a plurality of pixels connected to an initialization line and a first power source line;
- a sensor unit provided on the display unit and including a plurality of driving electrodes;
- a sensor driver providing a touch driving voltage to a plurality of driving lines connected to the plurality of driving electrodes;
- a power supply providing an initialization voltage to the initialization line and providing a first power source voltage to the first power source line;
- and
- a compensation circuit compensating for the initialization voltage.
A display device operating in a display driving period and a touch driving period overlapping with at least a portion of the display driving period, comprising:
- a plurality of driving lines connected to a plurality of driving electrodes;
- a first power source line connected to a cathode electrode of a light emitting element;
- an initialization line providing an initialization voltage to an anode electrode of the light emitting element;
- and
- a compensation circuit connected between the plurality of driving lines and the initialization line.
