Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0043] As mentioned in the background technology, the existing display panels are prone to brightness deviation during the display process. The inventors have found through research that the reason for this problem is that different positions of the display panel are affected by IR-Drop differently during display, resulting in different The driving currents of the sub-pixels at different positions are different, resulting in uneven display brightness of the display panel, which affects the display effect.

Abstract

The embodiment of the invention discloses a compensation method and device for a display panel. The compensation method of the display panel includes: obtaining the test gray scale of the display panel to be tested, performing gray scale expansion on the test gray scale, and determining the test mapping gray scale corresponding to the test gray scale; The actual display luminance and actual display chromaticity at different levels; the gray scale compensation formula for each display area of ​​the display panel is determined according to the target display luminance, actual display luminance, actual display chromaticity and target display chromaticity of multiple test mapped gray scales. The embodiments of the present invention improve the display uniformity of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to display technology, and in particular to a compensation method and device for a display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panel is a kind of self-luminous display panel. Due to the advantages of thinness, high brightness, wide viewing angle, high response speed and wide operating temperature range, OLED display panel is more and more popular. It is applied in various high-performance display fields. [0003] The problem of uneven display in the display process of OLED display panels is a research and development subject that the display panel industry has been concerned about for a long time. Contents of the invention [0004] The invention provides a compensation method and device for a display panel to improve the display uniformity of the display panel. [0005] In a first aspect, an embodiment of the present invention provides a compensation method for...
