Display Module Back Panel with Segmented Thickness Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving thinness and lightness while preventing foreign objects from entering through holes in the back panel, which affects yield and increases labor and material costs when protective films are used.
Innovation Solution
A display module design featuring a back panel with a first sub-panel having recessed regions of varying thickness, where the thickness in the first regions is greater than 0 and less than in the second region, reducing weight and preventing foreign object entry while maintaining support strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If through holes are formed in the back panel to reduce weight, then the weight of the back panel is reduced, but foreign objects can easily enter the display device through the through holes
Solution Approach 1:
The back panel is divided into multiple regions with different thicknesses: first regions with reduced thickness for weight reduction and second regions with greater thickness for foreign object prevention. This segmentation allows different functional requirements to be satisfied in different areas of the same component.
Solution Approach 2:
Different regions of the back panel are given different local properties - the first regions have reduced thickness (greater than 0 and less than the thickness in second regions) to reduce weight, while the second regions maintain greater thickness to prevent foreign object entry. This local differentiation resolves the contradiction between weight reduction and protection.
2Weight of moving object
If the thickness of the back panel is reduced to achieve thinness and lightness, then the weight is reduced, but the support strength may be compromised
Solution Approach 1:
The back panel implements local quality differentiation where first regions have reduced thickness for weight reduction while second regions maintain greater thickness for structural support. This allows the overall device to be lighter while critical support areas retain sufficient strength.
Solution Approach 2:
Instead of uniformly reducing thickness in one dimension, the invention creates a multi-dimensional thickness distribution with varying depths across different regions, allowing weight reduction in non-critical areas while maintaining support strength in critical areas.
3Reliability
If a protective film is attached to the back panel to prevent foreign object entry, then protection is improved, but the cost of labor and material resources increases
Solution Approach 1:
The protective function is extracted from a separate protective film layer and integrated directly into the back panel structure itself. By forming second regions with greater thickness within the back panel, the panel itself provides protection, eliminating the need for additional protective films and reducing labor and material costs.
Solution Approach 2:
The protective function is merged with the structural back panel component. The second regions of the back panel serve dual purposes: providing structural support and preventing foreign object entry, thereby eliminating the need for separate protective films and simplifying the overall device structure.
