Profiled Display Panel Border Jagging Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Profiled display panels with non-rectangular shapes face display jagging issues due to mismatch between pixel units and border lines, leading to uneven brightness and jagged patterns near the border.
Innovation Solution
Incorporating low-brightness pixels and regular pixels in a profiled display panel, with low-brightness pixels having smaller aperture areas near the border that gradually increase towards the display region, allowing for a smooth transition in brightness and reducing brightness differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional rectangular pixel units are used in a profiled display panel, then the pixel structure is simple and easy to manufacture, but the pixel units cannot fully fit in the profiled border region causing jagged display patterns
Solution Approach 1:
The patent applies local quality by differentiating pixel structures into two types: regular rectangular pixels in the main display area and triangular pixels at the profiled border. This local differentiation allows the border region to achieve smooth profiled display while the main area maintains simple rectangular pixel structure, resolving the contradiction between manufacturing simplicity and border display quality.
2Manufacturing precision
If pixel units are trimmed to fit the profiled border, then the display smoothness at border is improved, but the pixel structure becomes complex and manufacturing difficulty increases
Solution Approach 1:
The patent segments the pixel array into distinct regions: regular rectangular pixels for the main display area and triangular pixels specifically for the profiled border region. This segmentation allows each region to have optimized pixel structures for its specific function, achieving smooth border display without complicating the entire pixel structure.
3Manufacturing precision
If low-brightness pixels with smaller aperture areas are used near the profiled border, then the display jagging phenomenon is reduced, but the brightness uniformity across the display region becomes challenging
Solution Approach 1:
The patent changes the aperture area parameter of pixels near the profiled border, making them progressively smaller than regular pixels. This parameter modification reduces the brightness of border-adjacent pixels, creating a gradient effect that eliminates the jagged display phenomenon while maintaining overall brightness uniformity through controlled aperture variations.

AI summary
A profiled display panel and a display device are provided. A display region of the profiled display panel has a profiled border. The profiled display panel includes a plurality of pixels including low-brightness pixels and regular pixels. Brightness of the low-brightness pixels is lower than brightness of the regular pixels under same driving voltage. The plurality of pixels forms a plurality of pixel rows extending in first direction and a plurality of pixel columns extending in second direction. Each of the pixel rows or the pixel columns includes at least one pixel group including the low-brightness pixels at one end of the pixel group and the regular pixels at the other end, and the regular pixels are arranged away from the profiled border. An aperture area of the respective low-brightness pixels in same pixel group is gradually increased in direction from the profiled border to the display region.
