Display panel driving method, display driving device and electronic equipment

Abstract

The embodiment of the invention discloses a display panel driving method, a display driving device and electronic equipment. The driving method comprises the following steps: acquiring any frame of to-be-displayed picture; dividing the picture to be displayed into a first partition picture, a second partition picture and a third partition picture; displaying the first partition picture by using the first display area, displaying the second partition picture by using the second display area, and displaying the third partition picture by using the third display area, wherein in the same frame ofpicture to be displayed, the sub-pixel density A1 for displaying the first partition picture, the sub-pixel density A2 for displaying the second partition picture and the sub-pixel density A3 for displaying the third partition picture meet the condition that A2 is larger than A1 and smaller than or equal to A3; the sub-pixels of the second display area comprise the first sub-pixels and the secondsub-pixels, and the display brightness L21 of the first sub-pixels and the display brightness L22 of the second sub-pixels meet the condition that L21 is larger than L22. According to the technical scheme, transition of the image quality and the brightness in the to-be-displayed image can be achieved through the second display area, and therefore the overall display quality can be improved.

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 device and electronic equipment. Background technique [0002] With the development of display technology, more and more display panels and display devices are applied in people's daily life and work. In order to improve user experience, the display panel structure can also be integrated with sensor modules, such as cameras, infrared sensors, etc., to integrate functions such as taking pictures and infrared detection. [0003] On this basis, in order to meet a higher screen-to-body ratio, light-emitting elements can also be placed in the area of ​​the display panel where the sensor module is correspondingly arranged. In order to ensure that the sensor module can work normally, the density of the light emitting elements in the area where the sensor module is placed is generally smaller than the density of the light e...

Problems solved by technology

As a result, the display effect of the area where the sensor module is placed is inconsistent with the display effect of the normal display area. The boundary between the two is obvious, which affects the overall display quality of the display screen.
