Hole-Punch Display Panel Pixel Arrangement Resolving Residual Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hole-punch display screens experience residual space due to mismatching pixel sizes and resolutions between the display area near the hole-punch and the area outside it, affecting display quality and fingerprint recognition.
Innovation Solution
A display panel design with distinct pixel areas, where the first display area surrounds the non-display area, and the second and third display areas are arranged perpendicular to the first, with sub-pixels of matching sizes in one direction and varying sizes in another, ensuring no residual space and high resolution in the second and third display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different resolutions and pixel arrangements are used in the display area near the hole-punch and outside it, then the display requirements are met, but residual space is created due to pixel mismatching
Solution Approach 1:
The patent applies local quality by implementing different pixel arrangements in different display areas. The first display area (near hole-punch) uses a first pixel arrangement while the second display area (outside near hole-punch) uses a second pixel arrangement, allowing each local region to be optimized for its specific requirements while maintaining overall display quality
Solution Approach 2:
The display area is segmented into multiple distinct regions (first display area, second display area, third display area) with different pixel configurations. This segmentation allows independent optimization of each area to eliminate residual space while meeting display requirements in each specific zone
2Loss of substance
If pixel sizes are adjusted to match between different display areas, then residual space is eliminated, but manufacturing complexity increases
Solution Approach 1:
The patent changes pixel arrangement parameters across different display areas, adjusting pixel sizes and configurations to match between adjacent areas. This parameter optimization eliminates residual space while managing manufacturing complexity through systematic parameter variation rather than arbitrary design changes

AI summary
Provided is a display panel and display device. The display panel includes a first non-display area, a first display area, a second display area and a third display area. The first display area at least partially surrounds the first non-display area, the first display area and the second display area are arranged in a first direction, the third display area is arranged with the first and second display areas in a second direction. The first display area includes first sub-pixels arranged in array, the second display area includes second sub-pixels arranged in array, and the third display area includes third sub-pixels arranged in array. Each first sub-pixel, each second sub-pixel and each third sub-pixel have a same size in the first direction; each first sub-pixel and each second sub-pixel have a same size in the second direction and each second sub-pixel has the size greater than each third sub-pixel in the second direction.
