Problems solved by technology

[0003] The pixel circuit of an OLED display panel includes a driving transistor and a plurality of switching transistors. Although the current pixel circuit can improve the display unevenness caused by the threshold voltage drift of the driving transistor caused by process and transistor aging through internal compensation, when the display When the panel is switching between high and low grayscale images, due to the hysteresis effect of the driving transistor, it will cause image sticking and affect the display performance

Abstract

The embodiment of the invention provides a driving method of a display panel, a driving chip and a display device, which relate to the technical field of display, and are used for effectively improving residual image phenomenon and improving display performance. The driving method comprises the following steps: monitoring the static pattern in the first display screen; when the display luminance value of the region where the static pattern is located and the display luminance value of the region where the background pattern is located satisfy the first preset condition, the region where the static pattern is located is defined as the first region; in the display process of the first display screen, the static pattern is controlled to move. Alternatively, in the display process of the second display screen after the first display screen jumps, the gray scale value of the sub-pixel in the second area is adjusted, wherein the second area is an area corresponding to the first area in the second display screen and the display brightness value is lower than the display brightness value of the first area. The driving method is used for driving the display panel to perform screen display.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a driving method of a display panel, a driving chip and a display device. 【Background technique】 [0002] With the development of display technology, Organic Light Emitting Display (OLED) display panels are more and more widely used due to their excellent characteristics such as self-illumination, high brightness, wide viewing angle, and fast response. [0003] The pixel circuit of an OLED display panel includes a driving transistor and a plurality of switching transistors. Although the current pixel circuit can improve the display unevenness caused by the threshold voltage drift of the driving transistor caused by process and transistor aging through internal compensation, when the display When the panel is switching between high and low grayscale images, due to the hysteresis effect of the driving transistor, it will cause image sticking and affect the display performance. ...
