Abstract

The invention relates to a drive method and a device of an OLED (Organic Light Emitting Diode) display panel. The method comprises the steps of acquiring image data of a picture to be displayed; judging a target picture type corresponding to the picture according to the image data; reading a target driving schedule corresponding to the target picture type; driving the OLED display panel according to the image data and the target driving schedule, and displaying the picture. According to the drive method and the device of the OLED display panel, different driving schedules are set aiming at different types of pictures, so that the different types of pictures can be scanned by adopting the different driving schedules, the problem of non-uniformity in display caused by short scanning time or low picture gray scale brightness can be avoided, and an MURA problem when the OLED display panel displays a low gray scale picture is effectively solved. The embodiment of the invention is particularly applicable to an AMOLED (Active Matrix / Organic Light Emitting Diode) display panel with high resolution.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and device for driving an OLED display panel. Background technique [0002] AMOLED (Active Matrix Organic Light Emitting Display, active matrix organic light-emitting diode) display is an active self-luminous display, usually used for high-definition large-size display devices, which pass thin film transistors (Thin Film Transistor, TFT) Build the pixel circuit to supply current to the OLED device. [0003] In order to reduce the image flickering of the screen, the refresh rate of the traditional AMOLED display is set to 60Hz, that is, the display period of each frame of image is fixed at about 16.7ms. In one display cycle, multiple rows of pixels in the panel need to be scanned row by row. Therefore, at the same refresh rate, the higher the resolution of the display, the shorter the scanning time for each row (that is, the time for one row of frames). For example: HD...
