Information Display Surface Member Light Transmittance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display devices struggle to make a display panel invisible while maintaining clear visibility of the information displayed on it, especially when the display panel is covered with a surface member that needs to suppress external light transmission.
Innovation Solution
The information display device incorporates a surface member with a first layer and a second layer, where the second layer is positioned between the first layer and the display panel to adjust light transmittance, ensuring that only the information displayed on the display panel is visible through the surface member, while the display panel itself remains invisible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the surface member suppresses external light transmission to make the display panel invisible, then the display panel becomes invisible through the surface member, but the transmitted light from the display panel attenuates making it difficult to see the information
Solution Approach 1:
The surface member is divided into multiple layers: a first layer for suppressing external light transmission and a second layer for compensating light attenuation. This segmentation allows each layer to perform its specific function independently, resolving the contradiction between hiding the display panel and maintaining information visibility.
Solution Approach 2:
Different regions of the surface member have different optical properties. The first layer has high light suppression capability for invisibility, while the second layer has compensatory light transmission characteristics. This local differentiation of optical properties enables simultaneous achievement of panel invisibility and information visibility.
2Shape
If a surface member is added to cover the display panel for aesthetic purposes, then the designability of the space is improved, but the device complexity increases
Solution Approach 1:
Multiple functional layers (first layer for light suppression, second layer for transmittance compensation) are merged into a single integrated surface member. This combining approach achieves the aesthetic design goal while consolidating the structural complexity into one unified component rather than separate elements.
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
This configuration allows users to see the information displayed on the panel without being aware of its presence, providing a seamless design with no visible seams between the wall surface and the display region, and enhancing the aesthetic and operational functionality of the device.
Implementation Method 1
The second layer is configured to adjust light transmittance of the surface member. The second layer is configured to compensate difference of transmittance depending on a position on the first layer.

AI summary
An information display device is attachable to a structure, and includes a display panel and a surface member. The display panel has a display surface and is configured to display information on the display surface. The surface member is disposed on a display surface side of the display panel and is configured such that only the information displayed on the display surface of the display panel is visible through the surface member when the display panel is turned on. The surface member includes a first layer disposed on a front side, and a second layer disposed on the display panel side with respect to the first layer. The second layer is configured to compensate for a difference of transmittance depending on a position on the first layer.
