Under-Display Panel Layout for Camera Light Flux and Full-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies that maximize screen-to-body ratio by reducing display regions for camera placement result in non-displayable areas, limiting further improvement of screen-to-body ratio and affecting photosensitive sensor light flux.
Innovation Solution
A display panel design with multiple display regions, including a first region for a photosensitive sensor, a second region with dual pixel circuits for driving light-emitting elements, and a third main display region, optimizing pixel circuit areas and light-emitting element densities to ensure sufficient light flux and full-screen display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If display regions are removed to place camera under screen, then screen-to-body ratio is improved, but display area is reduced and photosensitive sensor light flux is insufficient
Solution Approach 1:
The display screen is divided into three distinct display regions with different pixel circuit configurations: first display region with first pixel circuits, second display region with second pixel circuits, and third display region with third pixel circuits. This segmentation allows each region to be optimized for its specific function, enabling full-screen display while ensuring sufficient light flux reaches the photosensitive sensor under the first display region.
Solution Approach 2:
Different pixel circuit areas are applied to different display regions based on local requirements. The first pixel circuits in the first display region have a smaller area to allow more light transmission to the photosensitive sensor, while the third pixel circuits in the third display region have a larger area for full display functionality. This local differentiation resolves the contradiction between display area and light flux.
2Area of stationary object
If display regions are removed to place camera under screen, then screen-to-body ratio is improved, but display completeness is degraded
Solution Approach 1:
The display screen achieves multi-functionality by simultaneously providing full-screen display capability and camera integration. The first display region allows light transmission for camera operation, while the second and third display regions provide complete display coverage. This universal design eliminates the need to sacrifice display completeness for camera integration.
3Illumination intensity
If pixel circuit area is reduced to allow more light transmission, then photosensitive sensor light flux is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different area parameters to pixel circuits in different display regions. The first pixel circuits have a first area optimized for light transmission, the second pixel circuits have a second area for balanced performance, and the third pixel circuits have a third area for display quality. This parameter differentiation allows each region to meet its specific requirements without imposing uniform high precision requirements across the entire screen.
