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

A method for driving a display panel, a driving chip and a display device are provided to ameliorate image retention and improve the display performance. The method includes: monitoring a static pattern in a first display image and defining an area where the static pattern is located as a first area when a display brightness value of the area and a display brightness value of an area where a background pattern thereof is located satisfy a first preset condition; and controlling the static pattern to move during displaying of the first display image, or adjusting grayscale values of sub-pixels in a second area during displaying of a second display image, to which the first display image jumps, the second area being an area, corresponding to the first area in the second display image and having a display brightness value lower than a display brightness value of the first area.

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. ...
