Special-Shaped Display Panel Edge Color Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Special-shaped display panels face issues with non-uniform colors and zigzag textures at their edges due to varying light extraction areas, leading to color cast problems and unsmooth border lines, which affect the visual effect.
Innovation Solution
A special-shaped display panel with a peripheral light-shading layer and edge pixels, where the area of the aperture portion and light-shading portion are defined such that their product is identical across all edge pixels, ensuring uniform transmittance and color display at the edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the peripheral area is designed into a zigzag structure to make edge pixels have identical area, then the color cast problem is improved, but the border line becomes unsmooth or zigzagged, adversely affecting visual effects
Solution Approach 1:
The patent applies local quality by introducing a peripheral light-shading layer specifically in the peripheral area to compensate for light extraction differences. Instead of uniformly adjusting all pixels, the solution locally modifies the peripheral area with a light-shading layer having specific optical properties to balance the aperture ratios of edge pixels without affecting the overall border line smoothness.
2Adaptability or versatility
If edge pixels have different light extraction areas due to special-shaped structure, then the display area can achieve special shapes, but the aperture ratio varies in different edge pixels causing color cast problems
Solution Approach 1:
The patent changes the optical parameters of the peripheral area by introducing a light-shading layer with specific optical density. This parameter change compensates for the varying light extraction areas of edge pixels, ensuring that despite different physical areas, the effective light transmission (aperture ratio) is uniform across all edge pixels, thereby eliminating color cast while maintaining special display shapes.

AI summary
A special-shaped display panel having a display area and a peripheral area, including: a peripheral light-shading layer at least partially located in the peripheral area and defining the display area; and a plurality of edge pixels, each of the edge pixels comprising an aperture portion located in the display area, and a light-shading portion located in the peripheral area and covered by the peripheral light-shading layer an area of the aperture portion of each edge pixel is defined as S, a transmittance of each edge pixel is defined as T, it is further defined that M=S*T, and the M values of the edge pixels are identical. Such solution improves the edge color cast problem of special-shaped display panel, makes the color displayed at the edge of the special-shaped display panel uniform, and improves the visual effect of the edge of the display panel.
