Backlight Module Narrow Frame Design via Hook Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display devices with backlight modules have a wide frame design due to the outer wall of the middle frame, which hinders the achievement of a narrow frame appearance, essential for competitive market designs.
Innovation Solution
A backlight module design featuring engagement slots on the backplane's side wall and hooks on the middle frame, where the hooks are connected through elastic members, allowing secure attachment without covering the backplane's side wall, thus reducing the frame width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the middle frame includes an outer wall to secure the backplane, then the structural stability is improved, but the frame width increases
Solution Approach 1:
The invention extracts and removes the outer wall component from the middle frame structure. Instead of using a traditional middle frame with outer walls to secure the backplane, the patent eliminates this component entirely and uses hooks directly integrated into the horizontal support portion to engage with engagement slots on the backplane, thereby achieving the same securing function with a narrower frame width
Solution Approach 2:
The invention changes the dimensional arrangement of the support structure by transitioning from a two-dimensional planar support (horizontal support portion) to a three-dimensional spatial arrangement using vertically extending hooks that engage with slots on the backplane. This dimensional change allows the support function to be achieved without increasing the horizontal frame width
2Device complexity
If the middle frame uses a simple horizontal support portion without vertical support, then the device complexity is reduced, but the reliability of securing the backplane deteriorates
Solution Approach 1:
The invention introduces elasticity and dynamic adjustment capability into the hook structure through the elastic member. The hook can dynamically adjust its position and apply adaptive securing force to the backplane, improving reliability while maintaining simple structure. The elastic member allows the hook to flex and engage reliably with the engagement slot without requiring complex mechanical support structures

Function Achieved in This Case
This design effectively reduces the frame width of liquid crystal display devices, enabling a narrow frame design by securing the middle frame to the backplane without requiring additional support, enhancing the aesthetic appeal.

AI summary
A backlight module includes a backplane and a middle frame. The backplane includes a bottom surface and a side wall. Multiple engagement slots are disposed at the side wall, and each has an engagement part. The middle frame includes a horizontal support portion having a first end connected with multiple hooks. Each of the hooks corresponds to one engagement slot. Each hook includes two connection arms. One end of the two connection arms connects with the first end of the horizontal support portion. The other end of the two connection arms is disposed with a connection member. The two connection arms are connected through an elastic member. The hooks are mounted in the engagement slots. The connection members and the engagement parts are engaged with each other such that the middle frame is secured in the backplane. The present invention also discloses a liquid crystal display device.
