Abstract
A driving method of display device configured to be applied to a display device capable of reducing the difference in brightness between areas with different widths of a display panel includes: receiving an input signal by a processor to generate an image signal and an original data enable signal, with the image signal and the original data enable signal configured to control the display panel; and generating a gate control signal and a transmission signal by the controller based on the image signal and the original data enable signal for a scan line driver and a data line driver respectively. The gate control signal comprises a plurality of enable periods for activating the plurality of scan lines respectively, and widths of the enable periods for activating scan lines with different lengths are different. Said display device and a display driving circuit are also disclosed.
