Embodiment Construction

[0027] With the development of display electronic products such as mobile phones, the increase of the screen-to-body ratio of organic light-emitting display panels has become a product trend, and the functional components necessary for mobile phones such as front cameras must become a major factor restricting the increase of screen-to-body ratio. In response to this problem, a solution for an off-screen camera has been proposed. Application terminals such as mobile phones are divided into a first display area M and a second display area N. The first display area M includes components and functions such as an off-screen camera. The second pixels in the second display area N are normally arranged, and the opening area of ​​the first pixels in the first display area M is reduced to provide a light-transmitting area, or, the pixels of the first pixels in the first display area M The density is reduced in order to provide the light-transmitting area, resulting in a relatively low br...

Abstract

The invention discloses a driving method of a display panel, a driving device thereof and a display device. In a partial display mode, different gamma curves are called for different display areas to drive different areas of the same screen. Specifically, the first display area corresponding to the setting of the under-screen sensor can call the first gamma curve with lower brightness, that is, the first display area is driven by the first gamma curve with lower brightness, which corresponds to the first gamma curve of normal display. The second display area can call the second gamma curve with higher brightness, that is, the second display area is driven by the second gamma curve with higher brightness, so that the first display area has a lower brightness than the second display area, which can Avoid and prevent the life span reduction caused by the high brightness display of the first display area for a long time.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a driving method of a display panel, a driving device thereof and a display device. Background technique [0002] With the development of display electronic products such as mobile phones, the increase of the screen-to-body ratio of organic light-emitting display panels has become a product trend, and the functional components necessary for mobile phones such as front cameras must become a major factor restricting the increase of screen-to-body ratio. In response to this problem, the solution of the under-screen camera has been proposed, and application terminals such as mobile phones are divided into two display areas, and parts and functions such as the under-screen camera are set under one display area. When the two display areas are loaded with the same current, the brightness of the display area of ​​the under-screen sensor (including the camera) is relatively ...
