Problems solved by technology

Due to the existence of IR voltage drop, the signal voltage transmitted by these signal traces gradually changes along the direction away from the signal terminal, resulting in uneven brightness of the light emitted by the array of light emitting devices, making the brightness uniformity of the image displayed by the OLED display device relatively Difference

Abstract

The invention discloses an image processing method and device, and a display device, which relate to the technical field of image processing and are used to improve the brightness uniformity of images displayed by the display device. The image processing method includes: receiving image luminance information, according to the luminance information of each first sub-image area included in the image luminance information including at least two binding point luminances and reference luminances, obtaining at least two binding point luminances and reference luminances contained in each first sub-image area. The gray scale compensation parameters of each binding point; according to the gray scale compensation parameters of at least two binding points contained in each first sub image area, the gray scale compensation information of each first sub image area is obtained; according to the M first sub image areas The gray scale compensation information of the image area performs gray scale compensation on the image information. The image processing apparatus applies the method described above. The image processing method provided by the invention is used for image processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device, and a display device. Background technique [0002] An organic light-emitting diode (Organic Light-Emitting Diode, OLED for short) display device is a display device made of organic light-emitting diodes. Because OLED display devices have excellent characteristics such as self-illumination, high contrast, wide viewing angle, and flexibility, they are considered to be an emerging application technology for next-generation flat-panel display devices. [0003] Existing OLED display devices mainly include a display driving circuit and a light-emitting device array. The display driving circuit is composed of an arrayed pixel compensation circuit for driving the light-emitting device array to emit light, thereby realizing image display. In order to drive the array of light-emitting devices to emit light, various signal traces suc...
