Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with multiple display panels face a reduction in display quality due to differences in pixel density and sharpness between panels, particularly when using multiple display panels for enhanced image viewing and touch-input options.
Innovation Solution
A display device design featuring a substrate with a first display area of higher pixel density and a second display area with diffraction patterns, where the pixel density and diffraction pattern arrangements are optimized to reduce sharpness differences between the two areas, thereby enhancing overall display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If multiple display panels are used to increase display area and functionality, then the display area size increases, but the display quality and sharpness uniformity deteriorate due to different pixel densities between panels
Solution Approach 1:
The patent applies local quality by implementing different pixel densities in different display areas. The first display area has a first pixel density while the second display area has a second pixel density that is different from the first. This allows each area to be optimized for its specific function - the first area for high-quality image display and the second area for sensor integration and additional functionality, thereby resolving the contradiction between increasing display area and maintaining uniform display quality.
2Measurement precision
If pixel density is increased in the first display area to improve image quality, then image sharpness improves, but the difference in sharpness between the first and second display areas increases
Solution Approach 1:
The patent implements local quality by assigning different pixel densities to different display areas based on their functional requirements. The first display area uses a higher pixel density for superior image sharpness, while the second display area uses a different pixel density suitable for sensor integration. This localized optimization resolves the contradiction by allowing each area to have the appropriate sharpness for its purpose while maintaining overall system functionality.
Solution Approach 2:
The patent segments the display area into multiple distinct regions with different pixel densities. The display device includes a first display area with a first pixel density and a second display area with a second pixel density. This segmentation allows independent optimization of each area's pixel density to match its specific functional requirements, thereby resolving the sharpness uniformity contradiction.
3Adaptability or versatility
If sensors are arranged in the second display area to enable touch-input options, then functionality increases, but display quality and visibility deteriorate due to lower pixel density
Solution Approach 1:
The patent applies local quality by designing the second display area with a specific pixel density optimized for sensor integration and touch-input functionality. This area is distinct from the first display area in terms of pixel density, allowing it to prioritize sensor placement and interactive functionality while the first area maintains higher pixel density for primary image display. This resolves the contradiction between enhanced functionality and display quality by optimizing each area for its primary purpose.
