Embodiment Construction

[0062] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. 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.

[0063] An organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel includes a plurality of OLED devices. When manufacturing an OLED device, due to a certain precision of the process, there are certain differences among the plurality of OLED devices manufactured in the same process. When an OLED display panel is displayed, the difference between multiple OLED devices is manifested as a difference in luminance, which causes uneven display of the OLED...

Abstract

The invention discloses a Mura compensation data acquisition method, a Mura compensation data acquisition device and a display device. The Mura compensation data acquisition method comprises the following steps of: acquiring a first white image, a first red image, a first green image and a first blue image of a display panel under a preset gray scale, determining a Mura area of the display panel based on the first white image, dividing a compensation area of the display panel, carrying out three-primary-color separation on the first white image in the compensation area, respectively carrying out Mura correction on each image in the compensation area, respectively synthesizing the Mura-corrected images in the compensation area into a second white image and a third white image, and based onthe second white image and the third white image, determining a white image with a good compensation effect as a compensation white image, and obtaining Mura compensation data corresponding to the compensation white image. According to the embodiment of the invention, the Mura compensation effect of the display panel can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method, device and display device for acquiring Mura compensation data. Background technique [0002] The organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has a problem of poor brightness uniformity, that is, the Mura phenomenon. When compensating for Mura, it is necessary to obtain the luminance of the display panel, and calculate the Mura compensation data based on the luminance. However, the existing technical solutions have limitations on the Mura compensation of the display panel, and there is a problem that the Mura compensation effect is not good. Contents of the invention [0003] In view of this, the object of the present invention is to propose a method, device and display device for acquiring Mura compensation data, so as to improve the effect of Mura compensation of the display panel. [0004] To achieve...
