Embodiment Construction

[0036] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0037] An OLED display panel is usually composed of red R, green G, and blue B sub-pixels combined in a specific sub-pixel arrangement. In order to improve the apparent resolution of the display panel and take care of the material properties of different luminescent materials, the OLED display panel usually adopts different forms of subpixel rendering (Subpixel rendering, SPR). In a display panel using the SPR technology, especially in a display panel using an irregular arrangement of ...

Abstract

One embodiment of the invention discloses a display panel sub-pixel level mura compensation method, which comprises the following steps of: acquiring a display panel sub-pixel arrangement mode, grouping the display panel sub-pixels with the same color and the same offset position in each group, and manufacturing a display template; lightening the display panel according to the display template, and photographing a picture presented by the display panel to obtain a sub-pixel image; moving each sub-pixel image to obtain an offset image, wherein the position of the image of each sub-pixel in each offset image is the same as the logic position; and carrying out demura processing on the display panel. The sub-pixels of the display panel are grouped according to the colors and the offset positions, and the problem that physical positions and logic positions of pixels in different channels are staggered is solved.

Description

technical field [0001] The invention relates to the field of display screens. More specifically, it relates to a display panel sub-pixel level mura compensation method. Background technique [0002] With the development of OLED (Organic Light-Emitting Diode, also known as organic laser display) technology, screens produced with OLED technology occupy an important position in the display field, especially in mobile phone displays and tablet computer displays. In the OLED display production process, due to material purity, production process and other reasons, it is inevitable that such a phenomenon will occur, that is, when the same screen is displayed on the same display panel, different pixels (pixel areas) will actually have different brightness. This phenomenon is caused by the poor uniformity of the display panel, which is generally called the presence of Mura on the display. This phenomenon reduces the quality of the display effect and the production yield, and impos...
