Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing the size of the peripheral area while maintaining high resolution and high-speed driving, as the area occupied by drivers increases, limiting the expansion of the display area.
Innovation Solution
A transparent display device design that includes a substrate with a main display area and a peripheral area, featuring main and sub-light emitting diodes, transmission regions, and a driving circuit, where the sub-light emitting diodes are positioned in the peripheral area, allowing for reduced bezel space and expanded display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the driver area is increased to support high resolution and high-speed driving, then the driving performance is improved, but the display area is reduced
Solution Approach 1:
The patent places the driving circuit in the peripheral area rather than the main display area, utilizing the peripheral space that would otherwise be wasted. This spatial reorganization allows the main display area to be maximized while still accommodating the necessary driving components for high resolution and high-speed performance.
Solution Approach 2:
The driving circuit is positioned within the peripheral area that surrounds the main display area, effectively nesting the control components within the overall display structure. This allows the driving circuit to be integrated into the display device without occupying additional space beyond the peripheral region.
2Area of stationary object
If the peripheral area is reduced to expand the display area, then the display area is improved, but the space for driver placement is reduced
Solution Approach 1:
The patent utilizes the peripheral area as a dedicated zone for the driving circuit, transforming what would be non-display space into functional space. This allows the display area to extend to the edges of the substrate while the driving circuit is accommodated in the peripheral region, effectively eliminating the need for additional space beyond the periphery.
3Area of stationary object
If sub-light emitting diodes are placed in the peripheral area, then the display area is expanded, but the circuit layout complexity increases
Solution Approach 1:
The patent positions sub-light emitting diodes in the peripheral area, utilizing the space around the main display area. This allows the main display area to be maximized while the sub-diodes serve additional functions in the peripheral region, such as providing display output in previously non-display areas or serving as buffer elements.
