Abstract

The invention discloses a display panel driving method, a display driving circuit and a display device. After a data drive chip receives an image to be displayed sent by a graphics processor, it controls the connected display according to the position of the high-definition display area in the image to be displayed. Each row of sub-pixels in the high-definition display area in the panel is scanned line by line to meet the imaging and clear display of the high-definition display area; at the same time, the data driver chip controls the display panel to contain only low Each line of sub-pixels in the clear display area scans N lines at the same time; where N is an even number greater than 1, thereby effectively reducing the overall number of scanning lines displayed in each frame and saving the scanning time of each frame; while at the same scanning time per frame In some cases, the charging time of the display panel can be increased to meet the high-speed and low-power consumption display requirements.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method of a display panel, a display driving circuit and a display device. Background technique [0002] At present, as the requirements for display resolution and refresh rate are getting higher and higher, the requirements for the charging time of the display panel are more stringent. Especially in virtual reality technology (VR / AR), since it is necessary to perform real-time analysis on the area where the human eye is gazing, and then render the high-definition imaging area with high visual acuity required by the human eye, in order to achieve a better virtual The actual display effect requires very high display resolution and refresh rate. The current existing display mechanism is to scan each row of pixels in the display panel line by line, which can no longer meet the requirements of refresh rate and display resolution. Contents of the invention [000...
