Bent Edge Display Panel Corner Area Resolution Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with bent edges face challenges in maintaining uniform resolution and visibility, particularly in corner areas where the display transitions from a main display area to peripheral regions, leading to reduced image quality and user experience.
Innovation Solution
The display panel design includes a substrate with a main display area and corner areas, featuring specific arrangements of input lines, pixel circuits, and driving circuits, where the corner areas have extension areas with varying resolutions and pixel configurations that match or differ from the main display area, ensuring seamless transitions and improved visibility by connecting input lines and placing driving circuits strategically to supply signals effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel uses a bent edge structure with corner areas, then the display area is increased and adaptability is improved, but the visibility and image quality in corner areas deteriorate
Solution Approach 1:
The patent applies local quality by implementing different resolution levels in different regions of the display panel. The corner areas are divided into first corner areas with lower resolution and second corner areas with higher resolution, allowing each region to have optimized quality appropriate for its function while maintaining overall adaptability of the bent edge structure.
2Adaptability or versatility
If the display panel uses a bent edge structure with corner areas, then the display area is increased and adaptability is improved, but the image quality and uniformity deteriorate
Solution Approach 1:
The patent implements local quality by creating distinct resolution zones within corner areas. Second corner areas with higher resolution are strategically placed to maintain image quality in visible regions, while first corner areas with lower resolution are placed in less critical areas, thus maintaining manufacturing precision where it matters most while preserving adaptability.
Solution Approach 2:
The patent segments the corner areas into multiple sub-regions (first corner areas and second corner areas) with different resolution characteristics. This segmentation allows independent optimization of each segment, enabling the display to maintain high image quality in important areas while accepting lower quality in less critical areas, thereby resolving the contradiction between adaptability and image quality uniformity.
3Ease of manufacture
If driving circuits are arranged in corner areas to supply signals, then the device complexity is reduced and ease of manufacture is improved, but the visibility and image quality in those areas deteriorate
Solution Approach 1:
The patent segments corner areas into first corner areas (with driving circuits) and second corner areas (without driving circuits). This segmentation allows driving circuits to be placed in regions where they will not interfere with display quality, while preserving visibility in second corner areas that do not require driving circuits, thus resolving the contradiction between ease of manufacture and visibility.
Solution Approach 2:
The patent uses pixel circuits from the main display area as templates for creating pixel circuits in corner areas. By copying and adapting existing proven pixel circuit designs to corner areas, the patent simplifies the manufacturing process while ensuring that corner areas maintain adequate display quality, resolving the contradiction between ease of manufacture and visibility.
4Manufacturing precision
If different resolutions are used in extension areas, then the manufacturing precision and image quality are improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by implementing different resolution levels in different extension areas. First extension areas have lower resolution while second extension areas have higher resolution, allowing each local region to have optimized image quality appropriate for its specific requirements, thereby improving manufacturing precision without requiring the entire device to be complex.
Solution Approach 2:
The patent segments extension areas into multiple zones with different resolution characteristics. This segmentation enables independent optimization of each segment's image quality while keeping the overall device complexity manageable through modular design, resolving the contradiction between manufacturing precision and device complexity.
