Display Device Side Frame with Grooved Coupling for Thin Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving a thin profile while maintaining rigidity, which is crucial for modern display technologies such as liquid crystal displays (LCDs) to meet the demands of a thinner and more robust design.
Innovation Solution
The proposed display device incorporates a side frame with a symmetrical or asymmetrical cross-section, formed from metal materials, which includes grooves and reinforcement members to provide structural support and flexibility, coupled with an optical sheet and light assembly for efficient light distribution, and a back cover for protection, allowing for a thinner profile while maintaining rigidity.

If the display device uses a traditional frame structure, then structural strength is maintained, but the profile thickness increases
Solution Approach 1:
The frame is divided into a first frame portion and a second frame portion that are coupled together through coupling portions. This segmentation allows each portion to be optimized independently - the first frame portion provides structural support while the second frame portion enables thin profiling, resolving the contradiction between thickness and strength
Solution Approach 2:
The coupling portions are positioned within grooves of the respective frame portions, creating a nested structure where one frame portion fits into another. This nesting achieves strong structural connection while minimizing the overall profile thickness, as the coupling mechanism does not add significant external dimension

If the display device uses a thin profile design, then aesthetic appeal improves, but structural rigidity deteriorates
Solution Approach 1:
The frame uses composite construction with the first and second frame portions made from different materials or structural configurations. This allows optimization of each portion for its specific function - one for thinness and the other for rigidity - while their combination provides both properties simultaneously
Solution Approach 2:
The coupling portions extend in a direction perpendicular to the main plane of the frame, utilizing the Z-dimension to create structural connection without increasing the X or Y dimensions. This dimensional approach maintains thin profile while achieving structural rigidity through out-of-plane coupling elements
