Rounded Display Panel Pixel Layout for Smoother Corner Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels with rounded edges suffer from roughness issues in the rounded portions, leading to inaccurate image viewing and potential mistaken identification of the roughness as a product defect.
Innovation Solution
A display panel design featuring a substrate with a main display area, a round display area partially curved at the corner, and a middle display area between the main and round areas. The round display area includes multiple round display element areas with round display elements emitting light of the same color, driven by round pixel circuits in the middle display area, arranged in different rows with specific spacing to minimize visual recognition of the rounded boundary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If pixels are arranged in the rounded portion of the display area, then the display area can be fully utilized and the round shape is achieved, but the roughness is increased and image accuracy is degraded
Solution Approach 1:
The display area is segmented into three distinct regions: main display area with regular pixel arrangement, round display area with curved pixel arrangement, and middle display area serving as a transition zone. This segmentation allows each region to be optimized independently, with the middle display area specifically designed to bridge the visual gap between rectangular and rounded portions, thereby maintaining image accuracy while achieving the desired round shape.
Solution Approach 2:
Different pixel arrangement strategies are applied to different regions of the display. The main display area uses standard rectangular pixel arrangement for optimal clarity, the round display area uses curved pixel arrangement to achieve the desired shape, and the middle display area uses a transitional arrangement that gradually adapts from rectangular to curved patterns. This local differentiation ensures that each region has the optimal pixel arrangement for its specific function.
2Manufacturing precision
If the round display area is made visually smooth, then user perception of product quality is improved, but the pixel arrangement complexity increases
Solution Approach 1:
The display is divided into functionally distinct regions with clearly defined boundaries. The middle display area is specifically segmented as a transition zone that contains the pixel arrangement complexity, while the main and round display areas maintain simpler, more regular patterns. This segmentation isolates the complexity to a specific region, making the overall system more manageable.
Solution Approach 2:
The middle display area acts as an intermediary region that mediates between the rectangular main display area and the curved round display area. It contains the transitional pixel arrangements that gradually adapt from straight to curved patterns, thereby smoothing the visual transition without requiring complex arrangements throughout the entire display. This intermediary zone absorbs the complexity while preserving simplicity in the primary display regions.

AI summary
A display panel includes a substrate including a main display area, a round display area disposed at a corner portion of the main display area, and a middle display area between the main display area and the round display area, a round display element area arranged in the round display area and including round display elements, and a round pixel circuit area arranged in the middle display area and including round pixel circuits connected to the round display elements and emitting light of a same color. Round display element areas are arranged in different rows and round pixel circuit areas are arranged in different rows. One edge of the round pixel circuit area arranged in a first row from arranged in a same direction is spaced apart from one edge of the round pixel circuit area arranged in a second row by a first distance.
