Segmented Panel Support with Interstitial Reflective Layer for Display Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in maintaining uniform contrast due to differences in reflectivity between overlapping and non-overlapping areas of the display panel and the panel support member.
Innovation Solution
A display device design that includes a display panel, a panel support member with segments spaced apart, and a reflective layer disposed between the segments and the display panel, ensuring equal or matched reflectivity in both overlapping and non-overlapping areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a continuous panel support member is used, then structural strength is improved, but reflectivity uniformity deteriorates due to differences between overlapping and non-overlapping areas
Solution Approach 1:
The panel support member is divided into multiple segments spaced apart from each other, allowing the reflective layer to be disposed in the non-overlapping areas between segments. This segmentation enables uniform reflectivity across both overlapping and non-overlapping regions while maintaining structural integrity through the distributed segment configuration.
Solution Approach 2:
The reflective layer is selectively applied only in non-overlapping areas between the segments, creating different local properties: areas with reflective layer for enhanced reflectivity uniformity, and overlapping areas where the display panel contacts the panel support member directly. This local differentiation resolves the contradiction by addressing reflectivity issues only where needed.
2Illumination intensity
If segments are spaced apart to improve reflectivity uniformity, then reflectivity uniformity is improved, but device complexity increases due to additional components
Solution Approach 1:
The reflective layer is integrated with the panel support member structure, forming a unified component rather than separate elements. This merging approach maintains reflectivity uniformity benefits while reducing device complexity by eliminating the need for additional separate reflective components.
Solution Approach 2:
The panel support member segments serve multiple functions: providing structural support and simultaneously creating spaced-apart regions that enable uniform reflectivity when combined with the reflective layer. This multi-functionality reduces device complexity by making existing components do double duty rather than adding dedicated reflectivity control elements.
