Abstract
A display device and a method of driving the same are provided. The display device according to an embodiment of the disclosure includes: a display panel including a plurality of pixel lines in an area A, an area B, and an area C; a panel driver configured to: supply input image data to pixel lines in the area A during a first period; supply black image data to pixel lines in the area B during a second period following the first period; and supply input image data to pixel lines in the area C during a third period following the second period; and a timing controller configured to adjust a first input image data to be supplied to a last pixel line in the area A to a first adjusted data based on a first compensation table.
Claims18
A display device, comprising:
- a display panel including an area A, an area B, and an area C, the display panel having a plurality of pixel lines in each of the area A, the area B, and the area C, and the display panel being driven in periods including at least a first period, a second period, and a third period;
- a timing controller for modulating a third input image data corresponding to a specific first pixel line having a latest data write timing among the pixel lines of the area A to a modulated third input image data different from the third input image data, and modulating a fourth input image data corresponding to a specific second pixel line having an earliest data write timing among the pixel lines of the area C to a modulated fourth input image data different from the fourth input image data;
- and
- a panel driver for:
- sequentially writing each of a first input image data, a second input image data, and the modulated third input image data to a respective pixel line of the pixel lines of the area A during the first period, the modulated third input image data being written to the specific first pixel line of the area A,
- simultaneously writing black image data to the pixel lines of the area B of the display panel during the second period following the first period, and
- sequentially writing each of the modulated fourth input image data, a fifth input image data, and a sixth input image data to a respective pixel line of pixel lines of the area C during the third period following the second period, the modulated fourth input image data being written to the specific second pixel line of the area C.
A method of driving a display device including a display panel having a plurality of pixel lines disposed thereon and driven in periods including at least a first period, a second period and a third period, the method comprising:
- modulating a third input image data corresponding to a specific first pixel line having a latest data write timing among a plurality of pixel lines of an area A of the display panel to a modulated third input image data different from the third input image data, and modulating a fourth input image data corresponding to a specific second pixel line having an earliest data write timing among a plurality of pixel lines of an area C of the display panel to a modulated fourth input image data different from the fourth input image data;
- and
- sequentially writing each of a first input image data, a second input image data, and the modulated third input image data to a respective pixel line of the pixel lines included in the area A during a first period, the modulated third input image data being written to the specific first pixel line of the area A, simultaneously writing black image data to a plurality of pixel lines included in the area B of the display panel during a second period following the first period, and sequentially writing each of the modulated fourth input image data, a fifth input image data, and a sixth input image data to a respective pixel line of the pixel lines included in the area C during a third period following the second period, the modulated fourth input image data being written to the specific second pixel line of the area C.
A display device, comprising:
- a display panel including an area A, an area B, and an area C, each of the area A, the area B, and the area C including a plurality of pixel lines;
