Deformable Display Sheet Structure for Clear Images on Curved Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices used as stealth displays often create gaps between the wall and the display, leading to blurred images, especially when the wall surface is curved, preventing clear image display.
Innovation Solution
An information display device with a flexible substrate, a light emitter, a housing, and a deformable display sheet that conforms to the wall surface, guided by a light guide region, allowing the housing to deform and maintain contact with the wall, eliminating gaps and ensuring a clear image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional display device is installed on a curved wall surface, then the display device can be mounted on the wall, but gaps are formed between the display device and the wall surface, resulting in blurred images
Solution Approach 1:
The housing is designed with a deformable portion that can dynamically change its shape to conform to the wall surface. This deformable portion includes a first portion that maintains a space for the light emitter and a second portion that deforms to follow the curvature of the wall, eliminating gaps and ensuring clear image display on curved surfaces.
Solution Approach 2:
The display sheet is configured to be deformable and is disposed between the light emitter and the wall surface. This flexible display sheet can conform to curved wall surfaces while maintaining contact, preventing gaps from forming between the display device and the wall, thereby ensuring sharp image display.
2Strength
If the housing is made rigid to protect internal components, then structural strength is improved, but the housing cannot deform to conform to curved wall surfaces, creating gaps
Solution Approach 1:
The housing is divided into a first portion and a second portion. The first portion maintains structural strength and houses the light emitter, while the second portion is designed to be deformable to conform to the wall surface. This segmentation allows different parts of the housing to have different mechanical properties.
Solution Approach 2:
Different portions of the housing have different mechanical properties tailored to their specific functions. The first portion near the light emitter is designed for structural support, while the second portion is designed for deformability to match the wall surface curvature, optimizing both strength and adaptability locally.
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
The device enables clear image display on curved or irregular surfaces by eliminating gaps between the display and the wall, providing a sharp image without compromising the aesthetic integrity of the wall surface.
Implementation Method 1
a light emitter, disposed on the substrate portion, to emit light
Implementation Method 2
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.

AI summary
The information display device (20) comprises a substrate portion, a light emitter (22), a housing (23a,23b), a display sheet (24), and a light guide region. The light emitter (22) is disposed on the substrate portion and emits light. The housing (23a,23b) is disposed so as to cover the substrate. The display sheet (24) is attached to the housing (23a,23b), has a display surface on which various kinds of information are displayed by light emitted from the light emitter (22), and whose display surface is deformable. The light guide region is a space formed by the inner wall surface of the housing (23a,23b) and the display sheet (24), and guides the light emitted from the light emitter (22) to the display sheet (24). The housing (23a,23b) has a deformable portion (23b) that is provided to at least the portion in contact with the display sheet (24), and that is more readily deformable than the substrate portion in a direction intersecting the surface of the display sheet (24). The housing (23a,23b) and the display sheet (24) deform along the wall surface with which the display sheet (24) comes into contact.
