Abstract

The embodiment of the invention discloses a brightness compensation method and device for a display panel, and the display panel comprises first display regions, a second display region, and a non-display region. In the row direction, the first display regions are located on the two sides of the non-display region; the brightness compensation method comprises the steps of: obtaining the display brightness of the first display regions and the display brightness of the second display region under the same gamma register parameter; adjusting the display brightness of the first display regions tothe display brightness of the second display region, and determining a compensation coefficient of a gamma register parameter of the first display regions; and correcting the display brightness of thefirst display regions according to the compensation coefficient. According to the technical scheme provided by the embodiment of the invention, the consistency of the first display regions and the second display region is improved, the problem of layering of the special-shaped display region of the display panel is improved, and the problem of layering of the special-shaped display region by adopting a Demura compensation scheme in the prior art can be solved, so that the production cost of a product is reduced, and the production efficiency of the product is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method and device for compensating brightness of a display panel. Background technique [0002] According to market demands, the display area of ​​an organic light emitting diode (OLED) display panel can be provided with slots, blind holes, and transparent displays, etc., but this also brings about the problem of irregular display in the display area. [0003] At present, the Demura compensation scheme is used to solve the layering phenomenon of the special-shaped display area, but there are problems of high production cost and low production efficiency. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a brightness compensation method and device for a display panel, so as to reduce the production cost of the product and improve the production efficiency of the product. [0005] In a first aspect, an embodiment of the ...
