Detachable Back Slices for LCD Backlight Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backlight modules for liquid crystal displays (LCDs) are difficult to replace when they become broken, as they are not designed for easy maintenance or repair.
Innovation Solution
A detachable back slice design for the backlight module, where each back slice can be freely detached and reassociated with the back board using sliding and U-shaped chute mechanisms, allowing for easy replacement of damaged lamps or LEDs without requiring extensive disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the backlight module is designed as an integrated unit, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The backlight module is divided into multiple independent back slices that can be detached from the back board. Each back slice contains specific light sources (LEDs or lamps) and can be removed and replaced independently, allowing easy repair without disassembling the entire module while maintaining the overall integrated structure.
2Manufacturing precision
If the backlight module uses a fixed structure, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The back slices are designed with dynamic attachment and detachment capabilities through sliding mechanisms and U-shaped chutes. The back slices can be securely fixed during operation (maintaining manufacturing precision) but can also be easily removed and reattached for maintenance (improving ease of operation).

AI summary
A direct backlight module comprises a first frame, at least two light sources, and a back board. The back board is fixed to the first frame and comprises at least two back slices connected to each other. Each of the at least back slices slips out from the back board.
