Display Pixel Layout With Light-Shielded Boundary Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with different functional areas, such as those containing electronic components like cameras, exhibit visible boundaries due to significant differences in pixel density and aperture ratio between these areas, affecting their aesthetic and functional integration.
Innovation Solution
The solution involves adjusting the pixel density and size in the boundary areas of the display device by using a light-shield member, without altering the through-hole size of the upper insulating layer, to minimize the visibility of these boundaries, and incorporating a filter layer with color filters to enhance light transmissivity and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the number of pixels and aperture ratio are adjusted to minimize boundary visibility, then the aesthetic appearance is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent changes the physical parameters of pixels in the transition area by adjusting either the number of pixels or the aperture ratio (size of through-holes) to create a gradual transition effect. This reduces the visibility of boundaries between different display areas having different pixel densities, thereby improving aesthetic appearance without requiring complex manufacturing process changes
Solution Approach 2:
The patent applies different pixel configurations to different areas: the first display area uses a first pixel configuration, the second display area uses a second pixel configuration, and the transition area uses an intermediate configuration. This local differentiation allows the boundary visibility issue to be addressed specifically in the transition zone without affecting the overall display quality or requiring complex global manufacturing changes
2Adaptability or versatility
If the pixel density is adjusted in different areas to add various functions, then the functionality is improved, but the boundary visibility increases
Solution Approach 1:
The patent creates a transition area with intermediate pixel characteristics between the first display area (with first pixel density) and the second display area (with second pixel density). This local intermediate configuration allows both functional areas to maintain their required pixel densities while the transition area gradually bridges the difference, reducing boundary visibility and improving aesthetic appearance
Solution Approach 2:
The patent divides the display device into three distinct areas: the first display area, the transition area, and the second display area. This segmentation allows each area to be optimized independently for its specific function while the transition area serves to bridge the visual discontinuity between areas with different pixel densities
3Ease of manufacture
If a simple process is used to adjust pixel density by using light-shield members, then the manufacturing complexity is reduced, but the precision of pixel density control may be compromised
Solution Approach 1:
The patent achieves pixel density adjustment by changing the aperture ratio (size of through-holes in the light-shield member) or the number of through-holes in the transition area. This parameter-based approach allows precise control of pixel density using a relatively simple light-shield member structure, maintaining both manufacturing simplicity and control precision

AI summary

The first through-hole of the insulating layer overlaps the first electrode of the first light-emitter, and the second through-hole of the insulating layer overlaps the first electrode of the second light-emitter, and at least a portion of the second through-hole overlaps the light-shield.
