Display Bracket with Variable Width for Structural Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices face challenges in reducing thickness and manufacturing costs while maintaining structural stability and optical performance, particularly in the integration of backlight units and optical layers.
Innovation Solution
The proposed display device incorporates a backlight unit positioned behind an optical layer, with a bracket system that includes a first and second portion, where the second portion is wider than the first, attached to the back surface of the display panel, allowing for a thinner design and simplified manufacturing by eliminating the need for screws or other fastening members, and enhancing adhesive strength through a grooved structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional fastening members (screws) are used to attach the bracket to the display panel, then structural stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes fastening members (screws) from the bracket attachment structure, extracting the complicating element while maintaining attachment functionality through adhesive bonding alone. This simplifies the overall device structure and reduces manufacturing complexity.
Solution Approach 2:
The patent combines the attachment function into a single integrated solution by using adhesive bonding to simultaneously secure both the optical layer and the bracket to the display panel, eliminating the need for separate mechanical fastening components.

3Ease of manufacture
If the bracket width is uniform throughout, then manufacturing is simplified, but adhesive strength is insufficient
Solution Approach 1:
The bracket features a variable cross-sectional width where the second portion (adjacent to the display panel) is wider than the first portion. This local variation in geometry concentrates adhesive in the critical bonding region, enhancing adhesive strength where it is most needed while maintaining manufacturing feasibility.

AI summary
A display device includes a display panel including a front substrate and a back substrate, a backlight unit disposed in the rear of the display panel, and a plurality of brackets attached to a non-display area of a back surface of the display panel. Each of the plurality of brackets includes a first portion and a second portion positioned between the first portion and the back substrate. A width of the second portion is greater than a width of the first portion. The second portion is positioned adjacent to the back substrate.
