Pixel Arrangement Structure for Under-Screen Optical Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen mobile phone displays face limitations in light transmittance, affecting the optical signal reception of under-screen functional elements like front cameras and IR holes, which restricts 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 such as Real and Pentile patterns to enhance light transmittance and optical signal reception, allowing for improved display quality and reduced color shift risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uniform high pixel density is used across the entire display, then display quality is improved, but light transmittance for under-screen functional elements deteriorates
Solution Approach 1:
The display panel implements different pixel densities in different regions: a first pixel area with lower pixel density and a second pixel area with higher pixel density. This local differentiation allows the first pixel area to transmit more light to under-screen functional elements while the second pixel area maintains high display quality, resolving the contradiction between uniform high pixel density and light transmittance.
2Area of stationary object
If under-screen functional elements are added, then screen-to-body ratio is improved, but optical signal reception deteriorates due to insufficient light transmittance
Solution Approach 1:
The display panel implements different pixel densities in different regions: a first pixel area with lower pixel density and a second pixel area with higher pixel density. This local differentiation allows the first pixel area to transmit more light to under-screen functional elements while the second pixel area maintains high display quality, resolving the contradiction between uniform high pixel density and light transmittance.
3Illumination intensity
If pixel density is reduced in the first pixel area, then light transmittance is improved, but display quality in that area deteriorates
Solution Approach 1:
The display panel implements different pixel densities in different regions: a first pixel area with lower pixel density and a second pixel area with higher pixel density. This local differentiation allows the first pixel area to transmit more light to under-screen functional elements while the second pixel area maintains high display quality, resolving the contradiction between uniform high pixel density and light transmittance.
