Abstract

The invention discloses a pixel color difference compensation method and system of a display panel, and a display device, which belong to the field of display technology. , collect the Y', x, y data of all pixels, and compare the chromaticity difference between different pixels on the display panel and the selected reference pixel with the preset value, and for pixels whose color difference value exceeds the preset value, by selecting the When the color difference value between the pixel and the selected reference pixel is just at the critical point that cannot be recognized by human eyes, the calculation method is used to calculate the compensation values ​​of all sub-pixels of the pixel to perform color difference compensation correction. The pixel color difference compensation system is used to realize the pixel color difference compensation method of the above display panel. The display device includes the above-mentioned pixel color difference compensation system of the display panel. The present invention can effectively solve the phenomenon of uneven brightness and darkness in the display panel and improve the yield rate of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a method and system for compensating pixel color difference of a display panel, and a display device. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of Flat Panel Display, which usually includes various types of display panels in various devices such as smart phones, notebooks, TVs and tablet personal computers. For example, a liquid crystal display (LCD, Liquid Crystal Display) panel, a plasma display panel (PDP, Plasma Display Panel) and an organic light-emitting diode (OLED, Organic Light-Emitting Diode) display panel and the like. Such displays are generally flat, ultra-thin display devices consisting of a large number of individually driven color pixels placed in front of a light source or reflector to generate images. Among many flat-panel displays, liquid cryst...
