Curved Display Support Back Plate Thickness Gradient
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Curved display devices with uniform thickness support back plates are thicker and heavier due to the need to counteract the resilience force of the display panel, which does not meet market demands for lightness and thinness.
Innovation Solution
A support back plate with a thickness gradient, where the middle region is thicker than the ends, and optionally featuring a main and sub-support back plate structure with stepwise thickness reduction and adhesive connections, to provide a sufficient support force while minimizing overall thickness and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a uniform thickness support back plate is used to counteract the resilience force of the display panel, then the required support force is achieved, but the thickness and weight of the curved display device increase
Solution Approach 1:
The support back plate employs a thickness gradient design where the thickness varies from the first end to the second end. Specifically, the thickness at the first end is greater than the thickness at the second end, creating localized structural strength where needed while reducing material usage in areas requiring less support. This resolves the contradiction by providing sufficient support force through strategic thickening at the first end while minimizing overall weight through thinning at the second end.
2Strength
If a uniform thickness support back plate is used to maintain structural integrity, then the support function is ensured, but the thickness of the curved display device increases
Solution Approach 1:
The support back plate features a thickness gradient where the thickness at the first end is greater than the thickness at the second end. This local variation in thickness provides enhanced structural integrity and support capability at the first end while maintaining overall structural strength. The gradient design ensures that the support function is fulfilled without requiring uniform thickness throughout, thereby reducing the overall thickness of the curved display device.
3Force
If the thickness at the first end is increased to provide sufficient support force, then the support capability is improved, but the weight of the support back plate increases
Solution Approach 1:
The support back plate implements a thickness gradient design where the thickness at the first end is greater than the thickness at the second end. This localized thickening at the first end concentrates the support force capability exactly where needed, while the thinner second end reduces overall material usage and weight. This resolves the contradiction by providing enhanced support force at the critical first end region without proportionally increasing the weight of the entire support back plate.
Solution Approach 2:
The support back plate is designed with non-uniform thickness distribution, effectively segmenting the structural support function across different regions. The first end region with greater thickness handles the primary support force requirement, while the second end region with lesser thickness contributes to overall structural continuity with reduced mass. This segmentation of structural function allows optimized weight-to-strength ratio.

AI summary
A support back plate and a curved display device are disclosed. The support back plate including a first end and a second end in opposition to each other, wherein the support back plate is bent into a shape of an arc face; and a thickness in the middle region of the support back plate is greater than that at the first end and the second end. The above-mentioned support back plate is used in a curved display device to solve the problem of a usual curved display device with more thickness and weight.
