3D Display Black Matrix and Grating Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display devices face challenges in balancing display effect and production capacity, particularly due to insufficient water vapor release in the black matrix, which requires an additional baking process and affects the overall performance.
Innovation Solution
The black matrix and grating are formed on a side of the first substrate facing away from the second substrate, eliminating the need for an additional baking process and improving both production capacity and display effect by integrating them on the light exit side of the 3D display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the black matrix is formed inside the display panel, then it provides shielding function, but it requires additional baking process and reduces production capacity
Solution Approach 1:
The black matrix is extracted from the internal structure and moved to the external surface of the first substrate. This relocation eliminates the need for additional baking processes while maintaining the shielding function, thereby improving production capacity without sacrificing reliability
2Manufacturing precision
If the black matrix and grating are formed separately, then each component can be optimized independently, but the process complexity increases
Solution Approach 1:
The black matrix and grating are merged into a single integrated structure formed on the surface of the first substrate. This combination allows both components to be optimized together while reducing process complexity, as they can be fabricated in a single step rather than separately
3Reliability
If the black matrix is formed on the light exit side, then water vapor release is improved, but the positioning precision must be maintained
Solution Approach 1:
The black matrix is positioned on the external surface of the first substrate, utilizing the third dimension (surface placement) rather than internal positioning. This dimensional change improves water vapor release while maintaining positioning precision through accurate surface placement
