Abstract

The embodiment of the invention discloses a display panel brightness adjusting method and system. The method comprises the steps of obtaining a total input current of all sub-pixels in display panel preset areas under a preset input gray scale; according to the total input current and a target total current, determining an area to be compensated of the display panel; obtaining display brightness of all the sub-pixels in the area to be compensated; according to the display brightness and target brightness, determining a display compensation value of all the sub-pixels in the area to be compensated; feeding back the display compensation value to the display panel for brightness adjustment, wherein the display panel comprises multiple preset areas, and each preset area comprises at least two sub-pixels. According to the display panel brightness adjusting method and system, uneven luminescence among all the sub-pixels of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a method and system for adjusting brightness of a display panel. Background technique [0002] With the development of display technology, the display effect of display products has been continuously improved, so that the application of display products has become more and more extensive. [0003] However, in existing display panels, due to reasons such as manufacturing process and aging of luminescent materials, it is easy to cause uneven light emission between sub-pixels, that is, when sub-pixels of the same color are input with the same image signal, the display brightness is different, which affects the image display quality. Contents of the invention [0004] The invention provides a method and system for adjusting brightness of a display panel, so as to improve uneven light emission among sub-pixels of the display panel. [0005] In a first aspect, an emb...
