Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices, the boundary visibility between the display area and component areas is prominent, limiting the integration of additional functions and aesthetics.
Innovation Solution
A display panel design with a substrate, pixel electrodes, and optical functional layers that include light-blocking materials and black matrices strategically positioned to minimize boundary visibility, combined with light-transmissive areas in the component region, enhancing the integration of components like cameras and sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light-blocking materials and black matrices are disposed in both main display area and component area, then image quality is improved, but boundary visibility increases and component integration is limited
Solution Approach 1:
The patent applies different structural configurations to different regions of the display panel. In the main display area, both the light-blocking material and black matrix are disposed to ensure high image quality. In the component area, only one of them (either light-blocking material or black matrix) is disposed, allowing components to be integrated while maintaining acceptable visual appearance. This regional differentiation resolves the contradiction between image quality and component integration capability.
2Adaptability or versatility
If display area is expanded to include component areas, then functionality is improved, but boundary visibility between display area and component area becomes prominent
Solution Approach 1:
The patent implements a transition region between the main display area and component area where the optical structure is gradually modified. By disposing only one of the light-blocking material or black matrix in the component area (rather than both), the patent creates a gradual transition in optical properties that reduces the visual prominence of the boundary, thereby reducing the harmful effect of visible boundaries while maintaining expanded functionality.
3Object-affected harmful factors
If light-blocking materials are disposed in component area, then boundary visibility is reduced, but light transmission for components is blocked
Solution Approach 1:
The patent strategically positions the light-blocking material and black matrix only in specific regions (main display area and transition region) while leaving the component area largely open for light transmission. This selective disposal allows the boundary visibility to be reduced in the component area while maintaining sufficient light transmission for component operation, resolving the contradiction between these two requirements.
