Pixel Arrangement Structure for Under-Screen Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing full-screen mobile phone displays have 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 having a lower pixel density than a second pixel area, featuring different sub-pixel arrangements, including Real and Pentile patterns, to reduce light emission and enhance light transmittance, allowing under-screen functional elements to receive more light signals.

Engineering Contradiction Analysis
1Measurement precision
If uniform high pixel density is used across the entire display, then display resolution is improved, but light transmittance decreases and under-screen functional element reception is affected
Solution Approach 1:
The patent applies local quality by dividing the display into different pixel density zones: a first pixel area with lower pixel density and a second pixel area with higher pixel density. This allows different regions to have different optical properties, enabling the first area to provide better light transmittance for under-screen functional elements while the second area maintains high display resolution where needed.
2Measurement precision
If higher pixel density is used, then display quality is improved, but sub-pixel service life attenuation increases
Solution Approach 1:
The patent implements local quality by creating a first pixel area with lower pixel density where sub-pixels experience less stress and longer service life, and a second pixel area with higher pixel density that provides superior display quality. This spatial differentiation allows the system to optimize both display quality and sub-pixel durability in different regions.
