Display Substrate with Variable Pixel Density for Camera Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for higher screen-to-body ratios in electronic displays is hindered by the presence of functional components like front cameras, which reduce pixel density and lead to visible boundaries and lower brightness in camera regions.
Innovation Solution
A display substrate design with varying pixel densities and arrangements, including high-density first display sub-regions for regular display and low-density second sub-regions for camera areas, combined with specific pixel unit configurations and transparent pixels to maintain brightness and reduce visible boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera components are added to increase functionality, then the screen-to-body ratio is improved, but the pixel density decreases and visible boundaries appear
Solution Approach 1:
The patent applies local quality by creating different pixel density zones: a first pixel region with higher pixel density and a second pixel region with lower pixel density where the camera component is located. This allows the display to have high functionality with the camera while maintaining high pixel density in the main display area, thus resolving the contradiction between functionality and pixel density.
2Adaptability or versatility
If camera components are added to increase functionality, then the screen-to-body ratio is improved, but visible boundaries and lower brightness appear in camera regions
Solution Approach 1:
The patent implements local quality by configuring different brightness characteristics in different regions. The first pixel region has higher brightness while the second pixel region (with camera component) has lower brightness. This localized approach allows the camera to be integrated while maintaining overall display brightness and reducing visible boundaries through careful boundary region design.
3Manufacturing precision
If pixel density is increased in the display region, then the display quality is improved, but the screen-to-body ratio is reduced due to camera components
Solution Approach 1:
The patent resolves this contradiction by applying local quality through spatial differentiation of pixel density. The first pixel region maintains high pixel density for quality display, while the second pixel region has reduced pixel density to accommodate the camera component. This allows the screen-to-body ratio to be increased by integrating the camera without compromising the overall pixel density of the main display area.
4Adaptability or versatility
If the display region is expanded to increase screen-to-body ratio, then the functionality is improved, but the pixel density decreases
Solution Approach 1:
The patent applies local quality by dividing the display into regions with different pixel densities. When the display region is expanded to include camera components, the first pixel region maintains high pixel density while the second pixel region (containing camera) has lower pixel density. This localized approach allows the screen-to-body ratio to be increased without causing overall pixel density degradation.
