A display panel and a drive method therefor, where when a gate electrode drive circuit () scans pixels line-by-line, a drive chip () controls a clock signal end to input a clock control signal (CK) into the gate electrode drive circuit (), which causes a gate electrode scan signal (G(n)) to be output by the gate electrode drive circuit (), and a data signal (Vd) output by a data signal end is controlled to be written to a corresponding row of pixel circuits (). Where an active level period of the clock control signal (CK) falls within an active level period of the data signal (Vd), and a start time for the active level period of the data signal (Vd) is at least 1-2 μs earlier than a start time for the active level period of the clock control signal (CK).

Display panel and drive method therefor

A display device, a luminance compensation circuit thereof and a luminance compensation method are provided. In the luminance compensation method, the display device includes a display region and a peripheral region located on a periphery of the display region, where the display region includes a first pixel region and a second pixel region, a pixel density of the second pixel region is lower than a pixel density of the first pixel region; the luminance compensation method includes: adjusting a power supply signal of the first pixel region and/or a power supply signal of the second pixel region, respectively, according to the first light-emitting luminance information of the first pixel region and the second light-emitting luminance information of the second pixel region.

Display device, luminance compensation circuit thereof and luminance compensation method

A gray scale display method is provided. The method includes: dividing a matrix arrangement taking a pixel unit as a display unit into a matrix arrangement taking a plurality of pixel units as the display unit, where the display unit including the plurality of pixel units is a pixel module, and the pixel unit includes at least one sub-pixel; in a case that an average gray scale of the pixel module is smaller than a preset value, displaying a part of the pixel units of the pixel module with a preset gray scale, where the preset gray scale is larger than the average gray scale.

Gray scale display method

A display control method, a display control module and a display device. The display control method is applied for a display device with a display panel and a data processing circuit, and includes: according to a to-be-displayed picture, detecting, by a black-screen area detection circuit, a black-screen display area of the display panel in an always-on mode; controlling, by a logic control circuit, to stop providing display data corresponding to the black-screen display area, for the data processing circuit. The display data corresponding to the black-screen display area included in the to-be-displayed picture is black-screen display data.
