Abstract
A display device includes: a display panel including a sub-pixel, the sub-pixel including: a first capacitor; a first transistor to generate a driving current, and including a control electrode connected to the first capacitor; a second transistor connected to the first capacitor, and to provide a data voltage or a reference voltage to the first capacitor in response to a write gate signal; and a light emitting element to receive the driving current to emit light; a data driver to selectively output the data voltage or the reference voltage to the first capacitor through a source channel; and a timing controller to control the data driver.
Claims20
A display device comprising:
- a display panel comprising a sub-pixel;
- and
- a data driver configured to provide a data voltage to the sub-pixel to emit light corresponding to the data voltage,
- wherein the data driver comprises an output buffer configured to:
- output the data voltage and an offset voltage to a data line connected to the sub-pixel when the data voltage is to be applied to the sub-pixel;
- and
- output a reference voltage and the offset voltage to the data line when the reference voltage is to be applied to the sub-pixel.
An electronic device comprising:
- a display device;
- and
- a processor configured to provide image data to the display device,
- wherein the display device comprises:
- a display panel comprising a sub-pixel;
- and
- a data driver configured to provide a data voltage to the sub-pixel to emit light corresponding to the data voltage, and
- wherein the data driver comprises an output buffer configured to:
- output the data voltage and an offset voltage to a data line connected to the sub-pixel when the data voltage is to be applied to the sub-pixel;
- and
- output a reference voltage and the offset voltage to the data line when the reference voltage is to be applied to the sub-pixel.
