Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in achieving a high screen-to-body ratio while maintaining both light-transmissive performance and display quality, particularly in light-transmissive display areas.
Innovation Solution
The implementation of a display panel design where sub-pixel groups in alternating light-emitting regions share a first pixel driving circuit and are controlled independently by switching circuits, allowing for alternating light emission and improved image processing, thereby enhancing image resolution and display quality while reducing the area occupied by pixel driving circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a photosensitive device is placed under the display panel to increase screen-to-body ratio, then light-transmissive performance is improved, but display quality and resolution deteriorate
Solution Approach 1:
The pixel array is divided into multiple sub-pixel groups, with each group containing sub-pixels of the same color. Multiple sub-pixel groups share a common pixel driving circuit, enabling independent control of each group while reducing the number of driving circuits needed. This segmentation allows the light-transmissive display area to maintain both light transmission capability and display quality.
2Manufacturing precision
If multiple pixel driving circuits are used to control sub-pixels, then display resolution is improved, but the area occupied by driving circuits increases, reducing light transmittance
Solution Approach 1:
Multiple sub-pixel groups containing sub-pixels of the same color are connected in parallel to share a common pixel driving circuit. This merging approach reduces the total number of pixel driving circuits required, thereby decreasing the area occupied by driving circuits and increasing the light-transmissive area, while still maintaining the ability to control individual sub-pixel groups for high-resolution display.
