Narrow Bezel LCD Coupling via Intermediate Frame Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display (LCD) devices face limitations in reducing the bezel width due to the thickness of the hook or screw coupling mechanism, which diminishes the coupling force between the intermediate and lower frames, making it challenging to achieve both a slim and lightweight design while maintaining a secure attachment.
Innovation Solution
The design incorporates a coupling portion on the intermediate frame that extends through a coupling hole in the lower frame, with a bent configuration that attaches to both inner and outer surfaces of the side wall portion, and uses adhesive members to secure the coupling portion to the side wall and display panel, enhancing the coupling force while reducing the bezel width.

Engineering Contradiction Analysis
1Force
If a hook or screw coupling mechanism is used between the intermediate frame and lower frame, then the coupling force is improved, but the bezel width increases due to the thickness of the coupling mechanism
Solution Approach 1:
The patent extracts the coupling function from the traditional hook or screw mechanism and relocates it to the display panel itself. The display panel is directly coupled to the lower frame, eliminating the need for separate coupling components that would increase bezel width. This direct coupling approach maintains the necessary coupling force while reducing the overall bezel width to achieve a narrower border design.
2Length of stationary object
If the bezel width is reduced to achieve a slim design, then the aesthetic appeal and modernity are improved, but the coupling force between frames deteriorates
Solution Approach 1:
The patent merges the coupling function with the display panel structure itself. Instead of having separate coupling components, the display panel is designed to directly couple with the lower frame. This integration allows the coupling force to be maintained through the panel's own structural features, enabling a reduced bezel width without compromising the structural integrity or coupling strength between frames.
3Stability of the object's composition
If traditional coupling mechanisms are used, then the structural stability is maintained, but the device complexity increases due to additional coupling components
Solution Approach 1:
The patent removes the separate coupling components (hooks, screws, or other mechanical coupling elements) from the system. By extracting these additional parts and integrating the coupling function directly into the display panel structure, the design achieves structural stability through a simpler, more streamlined configuration. This reduction in component count directly lowers device complexity while maintaining the necessary structural integrity.

AI summary
A display device includes: a display panel which displays an image; an intermediate frame on which the display panel is disposed; and a lower frame coupled to the intermediate frame and in which a coupling hole is defined. The intermediate frame defines: a support portion thereof extended facing a lower surface of the display panel, and a coupling portion thereof extending from a lower surface of the support portion and toward the lower frame. The coupling portion of the intermediate frame extends through the coupling hole defined in the lower frame to be attached to a surface of the lower frame.
