Back Cover Bending Structure for Display Rigidity and Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in achieving sufficient rigidity and heat-dissipation performance due to the thickness requirements of their back cover and inner plate support structures, which can lead to increased weight, complexity, and potential damage from impacts.
Innovation Solution
The display device incorporates an inward-bending portion at the front end of the back cover's vertical extension and a downward-bending portion on the inner plate, allowing for elastic deformation and improved heat dissipation, reducing the overall thickness and enhancing the structural integrity of the support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the back cover and inner plate are made thicker to improve rigidity, then structural strength is improved, but weight and device thickness increase
Solution Approach 1:
The back cover is designed with a bending portion that allows elastic deformation, enabling the use of thinner materials while maintaining structural integrity. This flexible design approach replaces the need for thick rigid structures, thereby reducing weight while preserving rigidity through controlled deformation capabilities.
Solution Approach 2:
The invention introduces a bending portion that adds a new dimensional aspect to the back cover structure. By creating a curved or folded configuration rather than a flat plate, the structural rigidity is enhanced through geometric design, allowing thinner materials to achieve the same strength as thicker flat structures.
2Strength
If the back cover and inner plate are made thicker to improve rigidity, then structural strength is improved, but device thickness increases
Solution Approach 1:
The bending portion in the back cover enables the use of thin-film structures that maintain rigidity through elastic deformation. The flexible design allows the back cover to resist lateral impacts without requiring increased thickness, as the bending geometry provides structural reinforcement.
Solution Approach 2:
By introducing a bending portion, the invention transforms the back cover from a two-dimensional flat plate to a three-dimensional curved structure. This dimensional change enhances rigidity through geometric configuration, allowing the device to maintain strength with reduced overall thickness.
3Device complexity
If conventional support structures are used, then structural simplicity is maintained, but heat-dissipation performance is insufficient
Solution Approach 1:
The bending portion of the back cover serves multiple functions simultaneously: it provides structural rigidity, absorbs lateral impacts through elastic deformation, and enhances heat dissipation by increasing the surface area in contact with the inner plate. This multi-functional design improves heat-dissipation performance without significantly increasing structural complexity.
4Ease of manufacture
If conventional flat support structures are used, then manufacturing simplicity is maintained, but impact resistance is insufficient
Solution Approach 1:
The bending portion is designed to allow elastic deformation when subjected to lateral impacts. This flexible structure can absorb impact energy through controlled bending and recovery, significantly improving impact resistance while maintaining manufacturing simplicity as the bending geometry can be integrated into standard molding processes.

Implementation Method 1
an inner plate including a horizontal portion attached to an inner surface of the horizontal portion of the back cover through an adhesive member and a downward-bending portion bent downward from a periphery of the horizontal portion so as to contact the inner surface of the horizontal portion of the back cover
Implementation Method 2
an inward-bending portion formed at an end of the vertical extension portion of the back cover... elastic deformation of the inward-bending portion prevents damage due to lateral impacts
Implementation Method 3
a downward-bending portion bent downward from a periphery of the horizontal portion so as to contact the inner surface of the horizontal portion of the back cover... elastic force from the downward-bending portion prevents the display from being cracked

AI summary
The present disclosure relates to a display device. A downward-bending portion is formed on an end of an inner plate arranged on the inner surface of a back cover, which is a back support structure of the display device, such that the outer surface of the downward-bending portion contacts the inner surface of the back cover, thereby improving the rigidity and heat-radiating performance of the inner plate, and guaranteeing that the elastic force from the downward-bending portion prevents the display panel from being damaged by cracks. Furthermore, an inward-bending portion is formed on the front end of the vertical extension portion of the back cover, thereby improving the rigidity of the back cover, and guaranteeing that elastic deformation of the inward-bending portion protects the display device from lateral impacts.
