Deformable Stealth Display Housing for Clear Curved-Wall Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stealth display devices often create a space between the wall and the display, leading to a blurry image, especially when the wall surface is curved, making it difficult to display a clear image.
Innovation Solution
An information display device with a deformable housing and display sheet that conforms to the wall surface, featuring a light emitter, substrate, and a light guide region, which ensures the light is properly directed and maintained in contact with the wall, eliminating gaps and blurriness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional display device is installed on a curved wall surface, then the display device can be mounted on the wall, but a space is created between the wall and the display device resulting in image blurring
Solution Approach 1:
The housing is designed with a deformable portion that can dynamically change its shape to match the curvature of the wall surface. This deformable portion includes a flexible backlight unit and housing structure that can bend and conform to curved surfaces, eliminating the space between the display device and the wall that causes image blurring.
Solution Approach 2:
The housing incorporates a flexible backlight unit with a deformable portion made of flexible materials that can bend and conform to curved wall surfaces. This flexible structure allows the display device to maintain close contact with the wall surface while mounted, preventing image blurring caused by gaps.
2Adaptability or versatility
If the wall surface is curved, then the display device can be installed on various wall types, but the image becomes more likely to be blurry due to increased space formation
Solution Approach 1:
The deformable portion of the housing can dynamically adjust its curvature to match different wall surface geometries. This allows the display device to be installed on various wall types (flat, convex, concave) while maintaining close contact with the wall surface to prevent image blurring.
Solution Approach 2:
The physical parameters of the housing (particularly the deformable portion) are designed to allow changes in shape and curvature. By changing the curvature parameter of the housing to match the wall surface, the display device can adapt to different wall types while maintaining image clarity.
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
Enables a clear image display on any wall surface, including curved surfaces, by ensuring the display device and housing deform to match the wall shape, preventing image blurriness and maintaining a sharp image.
Implementation Method 1
The light guide region is a space formed by the inner wall surface of the housing and the display sheet, and guides the light emitted from the light emitter to the display sheet

AI summary
The information display device comprises a substrate portion, a light emitter, a housing, a display sheet, and a light guide region. The light emitter is disposed on the substrate portion and emits light. The housing is disposed so as to cover the substrate. The display sheet is attached to the housing, has a display surface on which various kinds of information are displayed by light emitted from the light emitter, and whose display surface is deformable. The light guide region is a space formed by the inner wall surface of the housing and the display sheet, and guides the light emitted from the light emitter to the display sheet. The housing has a deformable portion that is provided to at least the portion in contact with the display sheet, and that is more readily deformable than the substrate portion in a direction intersecting the surface of the display sheet. The housing and the display sheet deform along the wall surface with which the display sheet comes into contact.
