Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in achieving high screen-to-body ratios while ensuring adequate light transmittance and display quality, particularly in areas accommodating imaging modules like under-screen cameras.
Innovation Solution
A display panel design with alternating arrangements of first and second repeating units in different display areas, featuring varying pixel and spacer densities, and tailored opening sizes to enhance light transmittance and uniformity, incorporating an under-screen camera solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pixel density is increased to improve display resolution, then the display quality is improved, but the light transmittance decreases
Solution Approach 1:
The patent applies different pixel densities to different display areas: the first display area (without imaging module) uses higher pixel density for better display quality, while the second display area (with imaging module) uses lower pixel density to ensure adequate light transmittance. This local differentiation resolves the contradiction by optimizing each area according to its specific functional requirements.
Solution Approach 2:
The display panel is segmented into multiple display areas with different pixel density characteristics. The pixel defining layer creates distinct regions where opening sizes and densities vary, allowing the system to simultaneously achieve high resolution in non-camera areas and high light transmittance in camera areas.
2Illumination intensity
If the opening area of sub-pixels is increased to improve light transmittance, then the light transmittance is improved, but the pixel density decreases
Solution Approach 1:
Different opening sizes are assigned to different display areas: sub-pixels in the second display area (with imaging module) have larger opening areas to enhance light transmittance for under-screen camera functionality, while sub-pixels in the first display area maintain smaller opening areas to preserve high pixel density and display resolution.
3Area of stationary object
If the screen-to-body ratio is increased by embedding imaging modules in the display area, then the screen-to-body ratio is improved, but the display uniformity deteriorates
Solution Approach 1:
The patent creates distinct display characteristics for different areas: the first display area maintains high pixel density and normal opening sizes for standard display quality, while the second display area uses lower pixel density and larger opening sizes optimized for light transmittance. This local differentiation allows the imaging module to be embedded while maintaining overall display uniformity through appropriate regional optimization.
Solution Approach 2:
The display panel is divided into multiple display areas with differentiated pixel densities and opening characteristics. This segmentation allows the system to accommodate imaging modules in specific areas while maintaining display quality in other areas, achieving both high screen-to-body ratio and acceptable display uniformity.
