Adjustable Display Panel Spacing via Integral Fixing Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with superposed panels require multiple cases to adjust the distance between panels, leading to increased costs due to the need for specialized components.
Innovation Solution
A display device structure featuring a front rim, intermediate case, and backlight with integral fixing holes allows for adjustable panel spacing by altering the thickness of the intermediate case without changing other components, using a simple and cost-effective fixing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of cases are prepared to adjust the distance between display panels, then the panel spacing can be adjusted to meet various user needs, but the manufacturing cost increases due to the need for specialized components
Solution Approach 1:
The single case structure incorporates multiple functions: it serves as the housing for the display device, the support for both display panels, and the mechanism for adjusting panel spacing. By making the intermediate case thickness adjustable, one universal case structure replaces what would otherwise require multiple specialized cases, thereby reducing manufacturing costs while maintaining adaptability for different spacing requirements
Solution Approach 2:
The intermediate case is designed with adjustable thickness rather than being a fixed static component. This dynamic characteristic allows the same case structure to accommodate different panel spacing requirements by simply changing the intermediate case thickness, enabling one case design to serve multiple spacing configurations without requiring multiple specialized cases
2Adaptability or versatility
If the case structure is altered to adjust panel distance, then the spacing between panels can be modified, but the device complexity increases due to the need for multiple case types
Solution Approach 1:
The single case design with adjustable intermediate case thickness serves as a universal structure that can accommodate different panel distances. This universal case replaces multiple specialized cases, simplifying the overall device structure while maintaining the ability to adjust panel spacing according to different display requirements
Solution Approach 2:
The case is divided into three main segments: the front rim, the intermediate case, and the rear cover. The intermediate case can be independently adjusted in thickness while the other segments remain constant. This segmentation allows for simple structural modification to achieve spacing adjustment without complicating the overall case structure

AI summary
A display device 1 of an embodiment of the invention has a first display panel (10A), a second display panel (10B) that is disposed behind the first display panel (10A), a front rim 20 that is disposed in front of the first display panel (10A), an intermediate cases (30, 35) that are disposed between the first display panel (10A) and the second display panel (10B), and support the first display panel (10A) and the second display panel (10B), and a backlight 40 that is provided behind the second display panel (10B). At least the front rim 20, intermediate cases (30, 35) and backlight 40 are provided with fixing holes 23a, 33a, 38a, 44a in their corners, and fixing is effected integrally at each corner. Thanks to such structure, a display device is provided in which the distance between the two display panels can be altered by an inexpensive method.
