Abstract

The invention discloses a display panel drive method, a display drive circuit and a display device. After a data drive chip receives the image to be displayed transmitted by a graphic processor, all rows of sub-pixels including a high-definition display area in the connected display panel are controlled to perform scanning row by row according to the position of the high-definition display area inthe image to be displayed so as to meet clear imaging display of the high-definition display area; meanwhile, the data drive chip controls all rows of sub-pixels only including a low-definition display area in the display panel to perform simultaneous scanning of N rows according to the position of the low-definition display area in the image to be displayed, wherein N is an even number greater than 1 so that the number of the overall scanning rows displayed by each frame can be effectively reduced and the scanning time of each frame can be saved; and the charging time of the display panel can be increased under the condition of the same scanning time of each frame and thus the display requirements of high speed and low power consumption can be realized.

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...
