Abstract
A display device includes a display unit which includes pixels, an emission driver which applies an emission control signal for allowing the pixels to emit light, and a signal controller which receives a data enable signal including an active period and a blank period during which an image signal is inputted and outputs a control signal for controlling the emission driver such that an emission period of the pixels is changed in response to a blank period.
Claims20
A display device comprising:
- a display unit which includes pixels;
- an emission driver which applies an emission control signal such that the pixels emit light;
- and
- a signal controller which determines a length of a blank period other than an active period during which an image signal is inputted by receiving a data enable signal from an external graphics source and generates a control signal for controlling the emission driver such that the pixels emit light during an emission period corresponding to the length of the blank period.
A driving method of a display device, the driving method comprising:
- receiving a data enable signal from an external graphics source;
- determining a length of a blank period other than an active period during which an image signal is inputted from the external graphics source using the data enable signal;
- and
- generating a control signal for controlling an emission driver for applying an emission control signal such that pixels included in a display unit emit light during an emission period corresponding to the length of the blank period.
A system comprising:
- an application processor which outputs data enable signals with different blank periods depending on a variable frame mode;
- and
- a display device which includes a display unit including pixels and a signal controller for controlling the display unit such that a period during which the pixels emit light is different depending on the blank periods.
