Foldable Display Aperture Patterns for Bend-Area Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display apparatuses suffer from image quality distortion and visibility issues in deformable areas, particularly in the folding or bendable regions, and exhibit aperture patterns that can be observed in these areas.
Innovation Solution
A display apparatus design with a deformable area featuring a folding axis and non-deformable areas, where aperture patterns are arranged at varying intervals to minimize image quality distortion and improve visibility, utilizing a structure that includes a display panel with plates and specific link areas to maintain image quality and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If aperture patterns are arranged in the deformable area with uniform intervals, then the manufacturing process is simple, but image quality distortion occurs in the folding area
Solution Approach 1:
The patent applies different aperture pattern intervals in different regions: a first interval in the deformable area and a second interval (different from the first) in the non-deformable area. This local differentiation resolves the contradiction by optimizing image quality in each region separately while maintaining a systematic manufacturing approach.
Solution Approach 2:
The patent changes the interval parameter of aperture patterns based on the mechanical properties of different display areas. By setting different interval values for deformable and non-deformable regions, the patent optimizes both image quality and structural integrity without requiring completely different manufacturing processes.
2Object-affected harmful factors
If aperture patterns are arranged at smaller intervals to reduce aperture pattern visibility, then visibility improves, but power consumption increases
Solution Approach 1:
The patent applies different aperture intervals in different regions to balance visibility and power consumption. In the deformable area where aperture patterns are more visible, a smaller interval is used to improve visibility. In the non-deformable area, a larger interval suffices, reducing power consumption while maintaining acceptable visibility.
Solution Approach 2:
The patent optimizes the aperture interval parameter based on the specific requirements of each display area, achieving a balance between visibility reduction and power consumption management through localized parameter adjustment.
3Adaptability or versatility
If the display panel is made flexible to enable folding, then adaptability improves, but image quality distortion occurs in the deformable area
Solution Approach 1:
The patent applies different aperture pattern configurations to different regions of the flexible display panel. The deformable area uses a first interval optimized for flexibility, while the non-deformable area uses a second interval optimized for image quality, thus resolving the contradiction between folding capability and image quality.
4Loss of energy
If aperture patterns are arranged with larger intervals to reduce power consumption, then energy efficiency improves, but aperture patterns become more visible
Solution Approach 1:
The patent strategically places aperture patterns with larger intervals in the non-deformable area where visibility is less critical, thereby reducing power consumption. In the deformable area, smaller intervals are used to maintain visibility, thus resolving the contradiction between energy efficiency and aperture pattern visibility through spatial differentiation.

AI summary
A display apparatus includes a display panel and at least one plate under the display panel. The at least one plate includes a folding axis defined at the middle portion of the plate, a variable area including the folding axis and a non-variable area disposed at both sides of the variable area. The variable area includes a first area including the folding axis, a first link area disposed at both sides of the first area, and a second area disposed at both sides of the first area with the first link area therebetween. The non-variable area includes a second link area connected to the second area and a third area connected to the second link area. The at least one plate includes at least one opening pattern disposed in the variable area, having a length parallel to the folding axis and a width perpendicular to the folding axis, and being spaced at a predetermined gap.
