Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light-blocking layers are added to reduce external light reflection and limit viewing angle, then image quality and privacy are improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-layer nested structure where first light-blocking layers are positioned between display elements and second light-blocking layers are positioned between first light-blocking layers and color filter layers. This nested arrangement of light-blocking layers at different hierarchical levels effectively reduces external light reflection and limits viewing angles while maintaining systematic organization, thereby improving image quality and privacy without excessive complexity increase.
Solution Approach 2:
The patent introduces light-blocking functionality in multiple spatial dimensions by arranging first light-blocking layers in a first direction and second light-blocking layers in a second direction crossing the first direction. This multi-directional arrangement creates comprehensive light blocking coverage from various angles, effectively limiting viewing angles and reducing external light reflection while maintaining a structured and manufacturable design.
2Object-affected harmful factors
If multiple light-blocking layers are implemented to enhance privacy and image quality, then viewing angle limitation is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the light-blocking function into segmented layers with distinct roles: first light-blocking layers are disposed between display elements to provide primary light blocking, while second light-blocking layers are disposed between first light-blocking layers and color filter layers to provide additional light blocking. This segmentation allows each layer to be optimized independently and simplifies the manufacturing process by enabling separate fabrication and assembly of functional modules.
Solution Approach 2:
The patent applies light-blocking layers with specific directional characteristics: first light-blocking layers extend substantially in a first direction and are arranged in a second direction, while second light-blocking layers extend in the first direction and are arranged in the second direction. This local quality optimization ensures that each layer provides light blocking effectiveness for specific viewing angles, achieving comprehensive viewing angle limitation while maintaining manufacturing simplicity through standardized layer configurations.
