Display Pixel Layout Hiding Circuits Around High-Transmittance Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display apparatuses with integrated components, the pixel circuits for driving display elements cannot be arranged in areas requiring high light or sound transmittance, leading to visibility of adjacent pixel areas by users.
Innovation Solution
A display apparatus design where pixel circuits are arranged in adjacent regions surrounding the component area, with specific configurations of pixel and display elements, data lines, and scan lines to minimize visibility while maintaining high transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pixel circuits are arranged in the component area to drive display elements, then device complexity is reduced, but light and sound transmittance deteriorates due to obstruction by pixel circuits
Solution Approach 1:
The display area is segmented into a component area (first region) and an adjacent area (second region). Pixel circuits are segregated to the adjacent area while display elements span both regions. This spatial segmentation allows the component area to maintain high transmittance for light and sound while pixel circuits in the adjacent area provide driving functionality, thus resolving the contradiction between device complexity reduction and transmittance maintenance.
2Reliability
If pixel circuits are arranged in an adjacent area surrounding the component area, then light and sound transmittance is maintained, but the adjacent area becomes visible to users
Solution Approach 1:
Display elements are configured to overlap both the component area (first region) and the adjacent area (second region) where pixel circuits are located. This merging approach allows the display elements to visually cover the pixel circuits in the adjacent area, making them imperceptible to users. Simultaneously, the pixel circuits remain functional in the adjacent area, maintaining high transmittance in the component area. This resolves the contradiction between maintaining transmittance and preventing visibility of the adjacent area.
