Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels face challenges in enhancing display quality, particularly in areas where electronic modules are disposed, due to limitations in light transmittance and resolution variations across different display areas.
Innovation Solution
A display panel design featuring a first display area with a specific light transmittance and resolution, and a second display area with higher light transmittance and lower resolution, where the second area has a different power voltage level to improve signal transmission and reception for electronic modules disposed below it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a display panel uses a single display area with uniform light transmittance and resolution, then the manufacturing process is simple, but the display quality is compromised in areas where electronic modules are disposed
Solution Approach 1:
The display panel is divided into two distinct display areas: a first display area with first light transmittance and first resolution, and a second display area with second light transmittance and second resolution. This segmentation allows each area to be optimized for its specific function, with the second area having higher light transmittance for electronic module signal transmission while the first area maintains standard display quality
Solution Approach 2:
Different regions of the display panel are assigned different optical and resolution characteristics. The second display area, where electronic modules are disposed, has higher light transmittance and lower resolution optimized for signal transmission, while the first display area maintains standard resolution and light transmittance for normal display purposes
2Reliability
If the second display area has higher light transmittance to improve signal transmission, then signal reception is enhanced, but the resolution in that area is reduced
Solution Approach 1:
The display panel implements local quality optimization by assigning different resolution characteristics to different areas. The second display area has second resolution optimized for signal transmission reliability, while the first display area maintains first resolution for high-quality visual display. This allows the system to achieve reliable signal transmission without compromising overall display quality
Solution Approach 2:
The system dynamically adapts to different functional requirements by having different resolution levels in different areas. The second display area operates with lower resolution specifically when electronic modules require enhanced signal transmission, while the first area maintains higher resolution for normal display operations
3Reliability
If different power voltage levels are applied to different display areas, then signal transmission is improved, but the device complexity increases
Solution Approach 1:
The power supply system is segmented into at least two separate power lines: a first power line providing first power voltage to the first display area, and a second power line providing second power voltage to the second display area. This segmentation enables different voltage levels to be applied to different areas, improving signal transmission reliability while managing the increased complexity through systematic power distribution
