Profiled Display Panel Sub-Pixel Layout for Luminance Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Profiled display panels with varying display widths suffer from noticeable luminance differences between regions, leading to a reduced visual effect and impaired user experience, especially when adjacent regions have different widths.
Innovation Solution
The display panel is designed with first and second regions arranged along a direction, featuring sub-pixel groups with varying numbers of sub-pixels. The number of sub-pixels in one sub-pixel group is greater than in another, and the number gradually decreases along the direction, ensuring alignment and load consistency across regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel uses regions with different widths to adapt to profiled structures, then the adaptability to electronic devices is improved, but the luminance uniformity between regions deteriorates
Solution Approach 1:
The patent applies local quality by configuring different numbers of sub-pixels in different regions. Specifically, the first region has a first number of sub-pixels while the second region has a second number of sub-pixels, where the first number is greater than the second number. This local differentiation compensates for the width variation and maintains luminance uniformity across the profiled display panel.
2Shape
If the display panel has adjacent regions with different widths, then the profiled shape is achieved, but the visual effect deteriorates due to noticeable luminance difference
Solution Approach 1:
The patent implements local quality by varying the sub-pixel count in different regions. The first region contains more sub-pixels than the second region, creating a gradual transition that reduces the luminance difference at the boundary between adjacent regions with different widths, thereby improving the overall visual effect while maintaining the profiled shape.

AI summary
A display panel includes sub-pixels, first and second regions arranged along a first direction, and first side and second side. First sub-pixel groups in the first region and second sub-pixel groups in the second region are arranged along the first direction, and include at least two sub-pixels arranged along the second direction. A number of the sub-pixels in the second sub-pixel group close to the first region is greater than a number of the sub-pixels in the second sub-pixel groups away from the first region. The first sub-region of the second region is closer to the first region than the second sub-region. From the first region to the second region, a variation rate of the numbers of the sub-pixels in the second sub-pixel groups in the first sub-region is greater than a variation rate of the numbers of the sub-pixels in the second sub-pixel groups in the second sub-region.
