Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display quality deteriorates in display devices configured by connecting multiple display panels due to the formation of connecting portions (joints).
Innovation Solution
A display device with a first and second display panel, each having bent end portions, where subpixels are provided at these end portions and a connecting portion with a light diffusion function is formed between them, incorporating a light diffusion layer with dispersed light diffusion particles in a thermosetting resin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are connected to form a larger display device, then the display area is increased, but display quality deteriorates due to formation of connecting portions (joints)
Solution Approach 1:
The patent applies local quality by providing a light diffusion layer specifically at the connecting portions (joints) between display panels, while the rest of the display panels maintain their original structure. This localized treatment addresses the display quality issue at joints without affecting the overall display area or requiring redesign of the entire display system.
2Manufacturing precision
If a light diffusion layer is provided at connecting portions to improve display quality, then luminance uniformity is improved, but the structure becomes more complex
Solution Approach 1:
The light diffusion layer is designed to perform multiple functions simultaneously: it diffuses light to improve luminance uniformity at joints, provides adhesive bonding between display panels, and maintains structural integrity. This multi-functionality reduces the need for separate components, thereby limiting the increase in structural complexity.
3Manufacturing precision
If bent end portions are used to arrange panels in a plane, then the joints become less visible, but the subpixel arrangement becomes more complex
Solution Approach 1:
The patent employs asymmetric bending of the end portions of display panels, where the bending radius and angle are specifically designed to make the joints less visible from the front viewing angle. This asymmetric geometric modification addresses joint visibility while the subpixel arrangement complexity is managed through the light diffusion layer that compensates for any irregularities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves display quality by enhancing front luminance ratios and suppressing luminance deterioration across different viewing angles, reducing image blur, and minimizing the visibility of joints.
Implementation Method 1
a light diffusion layer having dispersed a large number of light diffusion particles in a thermosetting resin

AI summary
A display device includes a first display panel including a first end portion that is bent, and a second display panel including a second end portion that is bent, wherein the first display panel and the second display panel are arranged in a plane such that the first end portion and the second end portion are adjacent to each other, each of subpixels is provided at respective one of the first end portion and the second end portion, and a connecting portion having a light diffusion function is formed between the first end portion and the second end portion.
