Abstract

Provided are a method for driving a display panel, a display driving device and an electronic device. The method includes: acquiring any one frame of the picture to de displayed; dividing the any one frame of the picture to be displayed into a first partition picture, a second partition picture and a third partition picture; displaying the first partition picture in the first display region, displaying the second partition picture in the second display region, and displaying the third partition picture in the third display region; where in a same frame of picture to be displayed, a density A1 of sub-pixels for displaying the first partition picture, a density A2 of sub-pixels for displaying the second partition picture and a density A3 of sub-pixels for displaying the third partition picture satisfy that A1≤A2≤A3; and where sub-pixels in the second display region include first sub-pixels and second sub-pixels.

Claims22

Dependent claims

A method for driving a display panel, wherein the display panel comprises a first display region, a second display region and a third display region;

wherein the second display region is disposed between the first display region and the third display region, and at least part of the first display region is reused as an optical element reserved region;
and
wherein the method comprises:
acquiring one frame of picture to be displayed;
dividing the frame of picture to be displayed into a first partition picture, a second partition picture and a third partition picture;
and
displaying the first partition picture in the first display region, displaying the second partition picture in the second display region, and displaying the third partition picture in the third display region;
wherein in response to displaying the second partition picture, sub-pixels in the second display region comprise first sub-pixels having display luminance L21 and second sub-pixels having display luminance L22, and L21>L22.
