Abstract

The invention discloses a driving method of a display panel and a display device, and relates to the technical field of display. The display panel comprises a plurality of pixel units; the driving method comprises the steps of driving the display panel to be lightened, obtaining a time interval D1 between previous screen turn-off and current lightening of the display panel, and comparing the D1 with a preset time D2; when D1 is greater than D2, driving the pixel units in a compensation mode, wherein the compensation mode comprises the steps that in a preset period, a first driving signal is adopted to drive a pixel unit, the first driving signal comprises a first data voltage and a first light-emitting control signal, the effective pulse signal duty ratio of the first light-emitting control signal is 0-effective compensation duty ratio, and the preset period comprises at least one frame; and when D1 is smaller than or equal to D2, driving the pixel units in a normal mode. By adjusting the voltage value of the first data voltage received by the pixel unit, the duty ratio of the effective pulse signal is reduced, the ghost shadow generated when the display panel is lightened is eliminated, and it is guaranteed that the image display is the target light-emitting brightness.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a driving method and a display device of a display panel. Background technique [0002] In the prior art, organic light-emitting displays have the advantages of low production cost, low energy consumption, self-illumination, wide viewing angle, and fast response speed, and are currently widely used in display fields such as mobile phones, tablet computers, vehicle-mounted display screens, and digital cameras. However, based on the actual usage of the current organic light-emitting display products, it is found that when the organic light-emitting display is in the off-screen state for a long time and is turned on again, problems such as low screen brightness and poor screen display effect will occur, reducing the the user experience effect. Contents of the invention [0003] In view of this, the present invention provides a method for driving a display panel ...
