Display Substrate Pixel Sharing Layout for Higher Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels have a lower resolution due to their design, which limits their ability to provide high-resolution display effects.
Innovation Solution
A display substrate with pixel units arranged in an alternating pattern, where first and second pixel units share sub-pixels in both row and column directions, utilizing a mask assembly with specific openings for each sub-pixel type to achieve a high-resolution display effect through a color-borrowing principle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional pixel arrangements are used, then manufacturing is simple, but resolution is low
Solution Approach 1:
Adjacent pixel units share common sub-pixels. Specifically, adjacent first pixel units share second sub-pixels, and adjacent second pixel units share first sub-pixels and third sub-pixels. This merging approach increases resolution by reducing the total number of independent sub-pixels needed while maintaining display quality through the color-borrowing principle.
Solution Approach 2:
Shared sub-pixels serve multiple functions by being part of multiple pixel units simultaneously. A second sub-pixel in a first pixel unit can be shared with an adjacent first pixel unit, and first/third sub-pixels are shared between adjacent second pixel units. This multi-functionality achieves high resolution without proportionally increasing the total sub-pixel count.
2Manufacturing precision
If more sub-pixels are added to increase resolution, then display quality improves, but manufacturing complexity increases
Solution Approach 1:
The patent merges adjacent pixel units by making them share common sub-pixels. This reduces the total number of sub-pixels that need to be manufactured and positioned, thereby simplifying the manufacturing process while achieving high resolution through the color-borrowing principle.
Solution Approach 2:
Each sub-pixel is designed to serve multiple pixel units through sharing arrangements. This universal usage reduces the overall sub-pixel count required for high-resolution display, making the manufacturing process more feasible and less complex.
3Manufacturing precision
If sub-pixels are shared between adjacent pixel units, then resolution increases, but sub-pixel arrangement complexity increases
Solution Approach 1:
The patent combines adjacent pixel units through shared sub-pixels in systematic patterns. First pixel units share second sub-pixels with adjacent first pixel units, while second pixel units share first and third sub-pixels with adjacent second pixel units. This organized merging achieves high resolution with manageable arrangement complexity.
Solution Approach 2:
The display is segmented into alternating first and second pixel units with distinct sub-pixel sharing patterns. This segmentation creates a regular, predictable arrangement that simplifies the overall design while achieving high resolution through the color-borrowing principle.
