Abstract:
A display panel includes a first plurality of pixels in first pixel rows corresponding to a first plurality of gate lines, a second plurality of pixels in second pixel rows corresponding to a second plurality of gate lines, and a gate driver coupled to the first plurality of gate lines and the second plurality of gate lines, the gate driver is configured to in a first display mode, turn on the first plurality of pixels and the second plurality of pixels, and in a second display mode, turn off the first plurality of pixels and turn on the second plurality of pixels. By turning off the pixels in the plurality of rows disposed in the dark areas, the number of the pixels to be driven can be reduced while obtaining a sufficient pixel compensation time, thereby driving the display panel at high speed.
