Abstract

The invention provides a display panel and a method for adjusting the aperture ratio of pixels. The method for adjusting the pixel aperture ratio includes: according to T 0 At this time, the first chromaticity coordinates and the first luminance values ​​of different color sub-pixels of the display panel calculate the second chromaticity coordinates of white light; F At this moment, the display panel displays the third chromaticity coordinates and the third brightness values ​​of sub-pixels of different colors, T F =T 0 +F, then calculate T according to the principle of color matching F The fourth color coordinate of white light; use the second chromaticity coordinate and the fourth chromaticity coordinate to calculate the white light color difference between the two; if the white light color difference is greater than the predetermined threshold, adjust the aperture ratio of the corresponding color and re-simulate T F The color coordinates and luminance values ​​of sub-pixels of different colors at any moment, until the fourth chromaticity coordinates whose color difference of white light is less than or equal to a predetermined threshold are obtained. The method of the invention can improve the color shift generated during the use of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a method for adjusting the aperture ratio of a pixel. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) technology has developed rapidly, and has become a promising technology most likely to replace LCD (Liquid Crystal Display, Liquid Crystal Display). [0003] However, organic light-emitting diodes have long suffered from a short lifetime. During the use of OLED screens, due to the different attenuation trends of BGR (blue sub-pixels, green sub-pixels and red sub-pixels), OLED screens will have a color cast after a period of use, which greatly affects the visual experience of customers. [0004] For example, if the blue sub-pixel decays too fast, the screen will appear yellowish after a period of use; if the green pixel decays too quickly, the screen will appear purple after a period of use; if ...
