Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data lines are extended to serve multiple subpixel groups, then device complexity is reduced, but signal transmission reliability deteriorates due to longer transmission paths
Solution Approach 1:
The patent divides the display into multiple subpixel groups (first, second, third, fourth subpixel groups) and assigns different data lines to each group. The first data line serves the first and third subpixel groups, while the second data line serves the second and fourth subpixel groups. This segmentation allows each data line to serve multiple groups while maintaining manageable transmission paths through strategic grouping.
Solution Approach 2:
The patent uses a matrix scanning approach where data lines are selectively activated in a sequential manner (first section, second section, third section, fourth section). This temporal dimension allows a single data line to serve multiple subpixel groups at different time periods, effectively reducing the physical number of data lines needed while maintaining reliable signal transmission through controlled activation sequences.
2Shape
If bezel thickness is reduced, then aesthetic appeal and display area ratio are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the display substrate into distinct display areas and peripheral areas, with clear definitions of first, second, third, and fourth subpixel groups. This segmentation allows precise control over the display boundary and bezel regions, enabling thin bezel design while maintaining manufacturing precision through well-defined structural zones.
Solution Approach 2:
The patent introduces shielding layers as intermediary structures between the data lines and surrounding components. These shielding layers help confine electromagnetic fields and prevent interference, allowing for tighter packing of components and thinner bezels while maintaining signal integrity and manufacturing feasibility through standardized shielding structures.
