Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transmissive areas are increased to enhance light transmittance, then light transmittance is improved, but power supply stability deteriorates
Solution Approach 1:
The patent divides the power supply structure into mesh-shaped power lines distributed across multiple mesh blocks within pixel blocks. This segmentation allows power to be delivered through multiple distributed paths rather than concentrated lines, maintaining power supply stability while accommodating larger transmissive areas in the bezel region.
Solution Approach 2:
The patent transitions from traditional linear power lines to a two-dimensional mesh network structure. This dimensional change enables power distribution across the display surface without requiring visible linear paths, allowing transmissive areas to expand while power stability is maintained through the distributed mesh architecture.
2Reliability
If mesh power lines are added to stabilize power supply, then power supply stability is improved, but device complexity increases
Solution Approach 1:
The mesh power lines serve multiple functions simultaneously: they provide power supply, create transmissive areas for visibility, and form a regular pattern that simplifies manufacturing. This multi-functionality reduces overall device complexity despite the increased power distribution capability.
Solution Approach 2:
The patent uses uniform mesh blocks with consistent mesh-shaped power line patterns throughout the bezel area. This homogeneity in structure simplifies the manufacturing process and reduces design complexity, as the same mesh block design can be replicated across different regions.
3Illumination intensity
If mesh blocks with transmissive areas are introduced, then light transmittance is improved, but manufacturing complexity increases
Solution Approach 1:
The display is divided into standardized mesh blocks that can be manufactured independently and then assembled. Each mesh block contains a complete mesh-shaped power line structure and transmissive areas, allowing for modular manufacturing that simplifies production despite the complex internal structure.
Solution Approach 2:
The patent optimizes the mesh pattern parameters (spacing, line width, geometry) to achieve the desired light transmittance while maintaining compatibility with existing manufacturing processes. By carefully selecting these parameters, the complex mesh structure can be produced using standard fabrication techniques.
