Dual-Area Display Pixel Layout With Shared Extension Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices struggle to effectively display images in areas where electronic elements such as cameras and sensors are located, as existing technologies do not efficiently integrate these components with image display areas without compromising resolution or transmittance.
Innovation Solution
A display device design featuring a first display area with main sub-pixels and a second display area with pixel groups and extension lines, where the second display area has a different resolution and includes auxiliary sub-pixels and horizontal lines connected to the main sub-pixels, allowing for image display even in areas with electronic elements, with optimized transmittance and reduced line interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic elements such as cameras and sensors are located in the display area, then the display device gains additional functionality, but the image display quality and transmittance are compromised
Solution Approach 1:
The display area is divided into a first display area with main sub-pixels for high-quality image display and a second display area with pixel groups for displaying images around electronic elements. This segmentation allows different regions to serve different functions with appropriate quality levels.
Solution Approach 2:
Different display quality levels are applied to different regions: the first display area uses high-resolution main sub-pixels for primary image display, while the second display area uses auxiliary sub-pixels with lower resolution specifically in regions where electronic elements are located, maintaining overall functionality while preserving local image quality where needed.
2Manufacturing precision
If more horizontal lines are used to connect auxiliary sub-pixels, then the image display capability is improved, but the line interference and reduced transmittance occur
Solution Approach 1:
Extension lines are extracted and arranged in the transmission portion between pixel groups rather than having horizontal lines extend across the entire display area. This reduces the number of lines in the transmission region, minimizing line interference and improving transmittance while still providing adequate image display capability.
Solution Approach 2:
Extension lines are arranged in a direction substantially perpendicular to the arrangement direction of auxiliary sub-pixels, utilizing the transmission portion space efficiently. This dimensional arrangement reduces line interference in the horizontal direction while maintaining vertical connectivity.
3Manufacturing precision
If the second display area has the same resolution as the first display area, then the overall image quality is improved, but the complexity of connecting lines and electronic element integration is increased
Solution Approach 1:
The second display area uses auxiliary sub-pixels with lower resolution than main sub-pixels, providing sufficient image display capability for regions with electronic elements without requiring the full resolution of the first display area. This partial action approach reduces the number of connecting lines and simplifies the overall structure.
