6. The display device of claim 5 , wherein the display driver is configured to switch the driving mode to the second mode based on a detection of a second image data specifying a same color for all pixels of the display panel in the first image data.
7. The display device of claim 6 , wherein the same color is the first color or the second color.
8. The display device of claim 5 , wherein the display driver is configured to switch the driving mode to the second mode based on a detection of a third image data specifying a same color for two or more of the pixels of a predetermined number or more of successive horizontal lines.
9. The display device of claim 8 , wherein the same color is the first color or the second color.
10. The display device of claim 5 , wherein the display driver further comprises:
image data sorting circuitry configured to sort, based on the driving mode, a fourth image data based on the first image data to generate a sorted image data; and
a source driver configured to drive the source line based on the sorted image data.
11. A display driver, comprising:
image processing circuitry configured to receive a first image data;
control circuitry configured to generate a gate control signal to control, based on a determination that the first image data specifies a common color for at least two pixels of a display panel, an order in which a plurality of gate lines of display panel are driven; and
image data sortinq circuitry configured to sort the first image data based on the determination that the first image data specifies the common color for the at least two pixels.
12. The display driver of claim 11 , wherein the display panel further comprises:
a source line;
a first subpixel of a first color connected to the source line and a first gate line of the plurality of gate lines; and
a second subpixel of a second color connected to the source line and a second gate line of the plurality of gate lines, the second color being different from the first color.
13. The display driver of claim 12 , wherein the display panel further comprises:
a third subpixel of the first color connected to the source line and a third gate line of the plurality of gate lines; and
a fourth subpixel of the second color connected to the source line and a fourth gate line of the plurality of gate lines,
wherein the first and third subpixels of the first color and the second and fourth subpixels of the second color are alternatingly arrayed along the source line.
14. The display driver of claim 13 , wherein the display driver comprises:
a first mode to drive the first, second, third, and fourth subpixels in this order, and
a second mode to drive the second and fourth subpixels after driving the first and third subpixels.
15. The display driver of claim 14 , wherein the display driver is configured to switch, based on the first image data, a driving mode to drive the plurality of gate lines between the first mode and the second mode.
16. The display driver of claim 15 , wherein the display driver is configured to switch the driving mode to the second mode based on a detection of a second image data specifying a same color for all pixels of the display panel in the first image data.
17. The display driver of claim 15 , wherein the display driver is configured to switch the driving mode to the second mode based on a detection of a third image data specifying a same color for pixels of a predetermined number or more of successive horizontal lines.
18. The display driver of claim 15 , wherein the image data sorting circuitry is further configured to sort, based on the driving mode, a fourth image data based on the first image data to generate a sorted image data; and wherein the display driver further comprises a source driver configured to drive the source line based on the sorted image data.
