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

Provided by the present disclosure are a method and device for adjusting brightness and an OLED display. The method includes: receiving an instruction for adjusting the brightness of the OLED display; and adjusting the light emitting control signal according to the brightness value of the OLED display which is needed to be adjusted in the instruction. The duty ratio of one pulse period in the light emitting control signal is correspondingly adjusted by one unit each time the brightness of the OLED display needs to be adjusted by one unit.
