Display Sub-Pixel Asymmetry and Mask Segmentation for Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices experience glare due to external light reflection, and the manufacturing process often results in deposition materials being patterned incorrectly due to mask sheet deformation during extension.
Innovation Solution
A display device design featuring sub-pixels of different shapes and sizes, including square and rectangular forms, arranged to minimize light reflection and precise patterning, along with a mask assembly with tilted openings to maintain uniform deformation during manufacturing.

Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional display device is disposed in a vehicle, then the display device can be used in mobile applications, but glare occurs due to external light reflection
Solution Approach 1:
The patent applies asymmetry by arranging sub-pixels in non-uniform patterns with varying shapes (square, rectangular) and orientations. This asymmetric arrangement disrupts regular reflection patterns, reducing glare when viewed from different angles in mobile applications like vehicles.
Solution Approach 2:
The patent introduces dimensional variation by arranging sub-pixels at different orientations and positions rather than uniform grids. This multi-dimensional arrangement scatters reflected light across different angles, mitigating glare effects in mobile deployment scenarios.
2Area of stationary object
If a mask sheet is extended during manufacturing, then the mask can cover larger areas, but deformation occurs causing deposition material to be patterned incorrectly
Solution Approach 1:
The patent segments the mask structure into multiple sections or layers that can be independently controlled. This segmentation allows the mask to be extended over larger areas while maintaining dimensional stability in each segment, preventing deformation-induced patterning errors.
Solution Approach 2:
The patent employs parameter changes by adjusting mask material properties, tension distribution, or structural configuration during extension. These parameter adjustments compensate for deformation forces, enabling large-area coverage while preserving deposition pattern precision.
