Circular Display Radial Scan Lines Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses with quadrangular shapes have limitations in design flexibility and bezel area reduction, which restricts their ability to accommodate varying shapes and increase pixel density efficiently.
Innovation Solution
A circular display apparatus with radial first scan lines, parallel second scan lines, and circular data lines, along with a data driver on the rear surface, allows for a reduced bezel area and increased pixel density towards the outer non-display region, enabling a more flexible and efficient display design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a quadrangular display panel is used with conventional scan lines and data lines, then the display apparatus has a simple structure, but the bezel area cannot be reduced and design flexibility is limited
Solution Approach 1:
The display panel is configured with a circular shape instead of a conventional quadrangular shape. The scan lines are arranged radially from the center, and data lines extend in a circular direction, matching the circular geometry of the display panel to achieve design flexibility while maintaining structural simplicity
Solution Approach 2:
The scan lines are asymmetrically arranged with different configurations: first scan lines extend radially from the center, while second scan lines are positioned between adjacent first scan lines and extend parallel to one of them. This asymmetric arrangement optimizes the line configuration for the circular shape
2Quantity of substance
If the number of pixels is increased to enhance display quality, then the pixel density improves, but the bezel area increases
Solution Approach 1:
The density of pixels and the arrangement of scan lines and data lines are optimized locally across different regions of the circular display panel. The radial scan lines and circular data lines are configured to achieve higher pixel density in the display area while minimizing the bezel area, with each region optimized for its specific functional requirements
3Area of moving object
If the display area is expanded to cover more surface, then the image display area increases, but the non-display area (bezel) also increases
Solution Approach 1:
The circular shape of the display panel allows the display area to extend to the edges of the panel without requiring additional bezel space, as the curved geometry naturally optimizes the ratio of display area to non-display area compared to quadrangular configurations
