Circular Display Load Matcher Reduces Dead Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing dead space and maximizing the display area, particularly in circular or curved display formats, where the arrangement of pixels and drivers is inefficient.
Innovation Solution
The display device incorporates a load matcher, a pixel, and a repair pixel, with the load matcher positioned adjacent to the edge of the circular display area, the pixel spaced apart from the non-display area by the load matcher, and the repair pixel connected to the pixel and positioned in the non-display area. This configuration reduces dead space and allows for a more efficient use of the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If pixels and drivers are arranged in conventional formats, then the device structure is simple, but the display area is reduced due to dead space
Solution Approach 1:
The patent positions the load matcher in the non-display area adjacent to the circular display area edge, utilizing the third dimension (depth layer) rather than horizontal plane arrangement. This vertical stacking approach allows the load matcher to occupy non-display space, thereby increasing the effective display area without adding horizontal complexity to the pixel-driver arrangement.
Solution Approach 2:
The patent divides the display device into distinct functional zones: the circular display area, the non-display area surrounding it, and specific positioning of the load matcher adjacent to the display area edge. This segmentation allows each component to be optimally positioned in its designated zone, maximizing display area while maintaining structural organization.
2Area of stationary object
If the load matcher is positioned adjacent to the edge of the circular display area in the non-display area, then dead space is reduced, but the device structure becomes more complex
Solution Approach 1:
The patent merges the load matcher with the non-display area structure, positioning it adjacent to the circular display area edge. This integration allows the load matcher to utilize otherwise wasted non-display space, converting dead space into functional space without requiring separate structural additions that would increase device complexity.
3Area of stationary object
If repair pixels are disposed in the non-display area, then dead space is reduced and display area is enlarged, but the connection complexity between pixels and drivers increases
Solution Approach 1:
The patent introduces a lighting circuit as an intermediary component that facilitates connections between the repair pixels positioned in the non-display area and the main pixel array. This intermediary structure simplifies the connection topology by providing a centralized interface, reducing the complexity of direct point-to-point connections between scattered repair pixels and drivers.

AI summary
A display device includes a circular display area and a non-display area surrounding the circular display area. The display device may further include a load matcher disposed adjacent to an edge of the circular display area in the circular display area, a pixel disposed in the circular display area, spaced apart from the non-display area by the load matcher, and connected to the load matcher, and a repair pixel disposed adjacent to the edge of the circular display area in the non-display area, and connected to the pixel.
