Different-Density Display Panel Using SPR for Camera Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reduction in pixel density at the display region corresponding to an under-screen camera module results in lower resolution and adversely affects the display effect, while maintaining light transmittance for camera functionality.
Innovation Solution
A display panel design with distinct pixel densities in first and second regions, utilizing a pixel structure where sub-pixels in different colors are arranged in specific offset patterns, and a Sub-Pixel Rendering (SPR) technology to form dummy pixel units, enhancing resolution while ensuring maximum light transmittance.

Engineering Contradiction Analysis
1Illumination intensity
If the quantity of pixels is reduced on the display region corresponding to the under-screen camera module, then light transmittance is improved, but resolution deteriorates
Solution Approach 1:
The display panel is divided into two distinct display regions: a first display region with normal pixel density and a second display region corresponding to the under-screen camera module with reduced pixel density. This segmentation allows each region to be optimized independently - the first region maintains high resolution while the second region prioritizes light transmittance for camera functionality.
Solution Approach 2:
Different pixel densities are applied to different regions of the display panel based on local functional requirements. The first display region uses normal pixel density for high-quality display, while the second display region uses reduced pixel density to maximize light transmittance where the camera module is located, achieving local optimization.
2Illumination intensity
If the quantity of pixels is reduced on the display region, then light transmittance is improved, but display effect deteriorates
Solution Approach 1:
The display region is segmented into two zones with different pixel densities. The second display region corresponding to the camera module uses reduced pixel density to improve light transmittance, while the first display region maintains normal pixel density to ensure overall display quality and effect.
Solution Approach 2:
The display panel implements local quality differentiation where the second display region has optimized light transmittance for camera operation, while the first display region maintains high display quality, ensuring that the reduction in pixel density does not adversely affect the overall display effect.
