Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face challenges in achieving high transmittance, low power consumption, and high brightness while maintaining color performance, particularly due to inconsistent sub-pixel sizes leading to electrical characteristic differences and color mixing issues at high resolutions.
Innovation Solution
A display panel design with sub-pixel groups arranged in specific patterns, including red, green, and blue sub-pixels, where the green sub-pixels are emphasized to maintain resolution and image quality, and the sub-pixel density is adjusted to improve transmittance and reduce manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display panel is increased, then the image quality is improved, but the transmittance is decreased and brightness is reduced
Solution Approach 1:
The pixel array is divided into multiple sub-pixel groups, where each group contains a specific arrangement of red, green, and blue sub-pixels. This segmentation allows for optimized light transmission paths while maintaining high resolution, as the segmented structure reduces overall pixel density without sacrificing image quality.
Solution Approach 2:
Different sub-pixel groups have different compositions (e.g., some groups have 2 red sub-pixels while others have 1), allowing local optimization of transmittance and color performance. This local quality variation enables certain regions to have higher transmittance while maintaining overall high resolution.
2Measurement precision
If the resolution of the display panel is increased, then the image quality is improved, but the power consumption is increased
Solution Approach 1:
By segmenting the pixel array into sub-pixel groups with varying compositions, the total number of active pixels is reduced. This segmentation maintains perceived image quality through strategic placement of sub-pixels while reducing the overall power consumption of the display panel.
3Measurement precision
If the size of red and blue sub-pixels is increased to maintain color performance, then the color accuracy is improved, but the manufacturing complexity is increased
Solution Approach 1:
The patent employs different sub-pixel group compositions where some groups have 2 red sub-pixels and others have 1, allowing local optimization of color accuracy. This approach maintains color performance in critical regions while simplifying manufacturing in other regions, thereby reducing overall manufacturing complexity.
4Measurement precision
If the space between adjacent sub-pixels is reduced to increase resolution, then the pixel density is improved, but color mixing problems occur
Solution Approach 1:
The pixel array is segmented into sub-pixel groups with strategic arrangements of red, green, and blue sub-pixels. This segmentation creates natural spacing between different color sub-pixels within each group, preventing color mixing while maintaining high overall pixel density through the organized structure.
