Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pixel designs, such as RGB or RGBW, face limitations in increasing pixel density and display resolution, which restricts the enhancement of visual experience beyond a certain point.
Innovation Solution
A pixel array with parallelogram-shaped subpixels arranged in a delta pattern, where odd rows have subpixels of three colors sequentially arranged and even rows have subpixels of three colors in a different sequence, with specific angle and distance configurations, and a display method that calculates actual display information using a sampling area formed by connecting midpoints of adjacent subpixels to improve image quality and viewing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional RGB or RGBW pixel design is used, then the manufacturing process is simple, but the display resolution and visual experience are limited
Solution Approach 1:
The patent applies asymmetry by using parallelogram-shaped subpixels with specific angle configurations (greater than 0 degree and less than or equal to 20 degrees) instead of conventional rectangular subpixels. This asymmetric arrangement in a delta pattern enables higher display resolution by improving pixel distribution and reducing chromatic aberration, while maintaining manufacturability through a systematic design approach.
Solution Approach 2:
The patent transitions from conventional rectangular grid arrangement to a delta pattern arrangement where subpixels are positioned at specific angular orientations. This dimensional change in the arrangement pattern allows for better utilization of pixel space and improved visual resolution without requiring additional subpixels, effectively adding a new dimension to the traditional pixel structure.
2Manufacturing precision
If pixel density is increased to improve visual experience, then the display resolution improves, but the manufacturing process reaches maximum limit
Solution Approach 1:
The patent changes key parameters of the subpixel structure, specifically using parallelogram shapes with controlled angles (greater than 0 degree and less than or equal to 20 degrees) and specific spacing relationships (minimum distance of midpoints of bases greater than width of one subpixel and less than or equal to width of 3/2 subpixels). These parameter changes enable improved visual resolution while maintaining manufacturing feasibility by avoiding excessive pixel density increases.
Solution Approach 2:
The patent segments the pixel array into a delta pattern arrangement where subpixels of different colors are distributed in a specific geometric pattern rather than traditional rectangular grouping. This segmentation approach allows for improved visual resolution through better color distribution and reduced chromatic aberration, while keeping the manufacturing process manageable by maintaining a regular, repeatable pattern.
3Ease of manufacture
If subpixels are arranged in traditional rectangular pattern, then the manufacturing is straightforward, but chromatic aberration occurs and viewing angle is limited
Solution Approach 1:
The patent replaces the symmetric rectangular subpixel arrangement with an asymmetric parallelogram configuration at specific angles. This asymmetric arrangement disrupts the regular grid pattern that causes chromatic aberration in conventional displays, thereby reducing color fringing effects while maintaining a straightforward manufacturing process through systematic pattern repetition.
Solution Approach 2:
The patent introduces angular orientation as an additional dimension to the subpixel arrangement, transitioning from purely rectangular positioning to parallelogram-based delta patterns. This dimensional change improves viewing angle by distributing light emission in multiple orientations, while the regularity of the pattern keeps manufacturing simple.
4Ease of manufacture
If subpixels are arranged in traditional rectangular pattern, then the manufacturing is straightforward, but viewing angle is limited
Solution Approach 1:
The patent uses asymmetric parallelogram-shaped subpixels oriented at specific angles (greater than 0 degree and less than or equal to 20 degrees) to expand the viewing angle. This asymmetric configuration allows light to be emitted more uniformly across different viewing directions, improving the viewing angle experience while maintaining manufacturing simplicity through the regular delta pattern.
Solution Approach 2:
The patent adds angular orientation as a new dimension to the subpixel arrangement, moving beyond the conventional two-dimensional rectangular grid. This dimensional enhancement improves viewing angle by creating multiple light emission pathways, while the systematic nature of the delta pattern keeps the manufacturing process straightforward.
