Title:
PIXEL UNIT, MANUFACTURING METHOD THEREOF, DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/186938
Kind Code:
A1
Abstract:
Provided are a pixel unit, a manufacturing method thereof, a display panel, and a display device, relating to the technical field of displays. The pixel unit comprises a plurality of sub-pixels of different colors. Among the sub-pixels of different colors, the interference intensity of light emitted by a light-emitting layer of a sub-pixel of a target color is greater than that of light emitted by a light-emitting layer of a sub-pixel of other colors, thereby increasing a color shift of the sub-pixel of the target color, and reducing the percentage of the color displayed by the sub-pixel of the target color in the color displayed by the pixel unit. Thus, when the eyes observe the pixel unit from various angles, the colors displayed by the pixel unit are all closer to the colors displayed by sub-pixels of other colors, thereby improving the observed color consistency, and effectively alleviating the problems of color shifts and color asymmetry. Moreover, the invention adjusts interference intensities of lights emitted by sub-pixels of different colors so as to improve the effectiveness of the display panel, thereby simplifying manufacturing processes without affecting the color gamut.
