Windmill-Shaped Sub-Pixel Arrangement for Display Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face limitations in resolution and color-mixing efficiency due to the size constraints of traditional sub-pixels, which restricts the visual quality and stereo effect of displayed images.
Innovation Solution
The implementation of a pixel array comprising windmill-shaped sub-pixels with multiple separated parts around a center, allowing for smaller sub-pixel sizes and improved color-mixing effects by positioning adjacent sub-pixel parts in a specific arrangement, enhancing the display resolution and stereo effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional sub-pixels are used, then the display device can be manufactured with conventional structures, but the resolution is limited due to size constraints
Solution Approach 1:
The sub-pixel is divided into multiple separated parts (first sub-pixel part, second sub-pixel part, third sub-pixel part, fourth sub-pixel part) arranged in a windmill pattern around a center position. This segmentation allows each part to be smaller while maintaining the overall sub-pixel area, thereby improving resolution without significantly increasing manufacturing complexity.
Solution Approach 2:
The sub-pixel parts are arranged in a two-dimensional windmill pattern around a center position rather than in a simple linear or grid arrangement. This dimensional reconfiguration allows for more efficient space utilization and smaller individual part sizes, improving resolution while keeping the overall structure manageable.
2Manufacturing precision
If sub-pixel size is reduced to improve resolution, then more pixels can fit in the same area, but color-mixing efficiency deteriorates
Solution Approach 1:
The sub-pixel parts are arranged asymmetrically in a windmill pattern with specific angular relationships (e.g., 45 degrees between adjacent parts). This asymmetric arrangement optimizes the spatial distribution of different color sub-pixel parts, enabling better color mixing at the boundaries while maintaining small individual part sizes for high resolution.
Solution Approach 2:
Different regions of the pixel array have locally optimized sub-pixel arrangements. The windmill pattern creates specific local configurations where sub-pixel parts of different colors are positioned to maximize color-mixing efficiency at their boundaries, while the overall resolution is improved by the reduced size of individual parts.
3Ease of manufacture
If sub-pixel parts are positioned close together to improve color-mixing, then the stereo effect is enhanced, but the sub-pixel size cannot be reduced further
Solution Approach 1:
The sub-pixel parts are nested in a concentric windmill pattern around a common center position. This nesting allows the parts to be positioned close together for effective color mixing while the overall sub-pixel footprint remains compact, enabling both good color-mixing efficiency and high resolution to coexist.
