Mixed-Density Pixel Arrangement for Under-Screen Optical Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen mobile phone displays face inadequate light transmittance, which affects the optical signal reception of under-screen functional elements such as front cameras and IR holes, limiting the improvement of screen-to-body ratio.
Innovation Solution
A pixel arrangement structure with a first pixel area of lower pixel density adjacent to a second pixel area, utilizing different sub-pixel arrangements (Real and Pentile) to reduce light emission and enhance light transmittance, allowing under-screen functional elements to receive more light signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uniform high pixel density is used across the entire display, then display resolution is improved, but light transmittance for under-screen functional elements deteriorates
Solution Approach 1:
The patent applies local quality by creating a first pixel area with lower pixel density adjacent to under-screen functional elements and a second pixel area with higher pixel density in other regions. This allows the display to have different pixel densities in different locations, optimizing light transmittance where needed while maintaining high resolution in other areas.
Solution Approach 2:
The patent segments the display into multiple pixel areas with different pixel densities. The first pixel area containing under-screen functional elements has a lower pixel density (1/N of the second pixel area), while the second pixel area maintains higher pixel density. This segmentation allows simultaneous optimization of light transmittance and display resolution.
2Illumination intensity
If pixel density is reduced in the first pixel area, then light transmittance is improved, but display resolution deteriorates
Solution Approach 1:
The patent accepts local reduction in display resolution in the first pixel area where light transmittance is critical for under-screen functional elements. The second pixel area maintains high pixel density to preserve overall display quality, creating a localized compromise that optimizes the critical function of light transmission.
3Illumination intensity
If different pixel arrangement manners are used in different pixel areas, then light transmittance and visual quality are optimized, but manufacturing complexity increases
Solution Approach 1:
The patent uses different pixel arrangement manners (Real arrangement for first-category pixel groups and Pentile arrangement for second-category pixel groups) in different pixel areas to optimize local performance. The first pixel area uses Real arrangement for better light transmittance, while the second pixel area uses Pentile arrangement for optimized visual quality, accepting increased manufacturing complexity as a trade-off.
