Display Panel Boundary Pixel Structure for Under-Screen Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face display differences and boundary issues due to inappropriate structural arrangements of display panels, leading to difficulties in integrating photosensitive components and maintaining a uniform display across multiple display areas.
Innovation Solution
A display panel design with varying pixel densities between different display areas, incorporating a third pixel group adjacent to the boundary to ensure equal sub-pixel count and controlled brightness, allowing for under-screen integration of photosensitive components and alleviating display differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display areas with different pixel densities are provided to satisfy display requirements and facilitate integration of functional elements, then the display area and functionality are improved, but display differences and boundary issues are generated
Solution Approach 1:
The patent applies local quality by creating a third pixel group at the boundary between display areas with different pixel densities. This third pixel group has a specific sub-pixel configuration (with virtual sub-pixels) that is locally optimized to bridge the transition between the first and second display areas, ensuring uniform display appearance without requiring the entire display panel to have uniform pixel density.
2Adaptability or versatility
If the first display area has lower pixel density to increase light transmittance for under-screen integration, then photosensitive components can be integrated, but display brightness and quality are reduced
Solution Approach 1:
The first display area maintains lower pixel density specifically in regions where light transmittance is needed for under-screen integration, while the second display area can have higher pixel density for better display quality. The third pixel group at the boundary ensures that the lower pixel density region still provides adequate display brightness by optimizing the sub-pixel arrangement and light emission characteristics locally.
3Quantity of substance
If the number of sub-pixels is reduced in the first display area to increase light transmittance, then under-screen integration is enabled, but display quality and brightness are compromised
Solution Approach 1:
The patent reduces the number of physical sub-pixels in the first display area to increase light transmittance, but compensates by introducing virtual sub-pixels in the third pixel group at the boundary. These virtual sub-pixels are rendered through software or optical means to maintain the perceived pixel density and display quality, while the physical structure maintains lower density for better light transmittance.
