Backlight Module Detachable Light Source for LCD Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD backlight modules require complex and risky disassembly for lamp replacement, leading to potential damage of other components and increased difficulty with larger display sizes.
Innovation Solution
A modular structure where each lamp is installed on an independent base with clip-fastened holders and tracks, allowing for individual lamp replacement without disassembling the entire module, reducing the risk of damaging other components and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lamps are integrated into the backlight module with a fixed structure, then the module structure is compact and stable, but the complexity and risk of disassembly increases when replacing lamps
Solution Approach 1:
The backlight module is segmented into modular units where each lamp is mounted on a separate base that can be independently removed. The base includes a light source holder that secures the lamp, and this entire assembly can be detached from the backlight module without disassembling other components. This segmentation allows individual lamp replacement while maintaining overall module integrity.
Solution Approach 2:
The lamp is extracted from the integrated backlight module structure and mounted on a detachable base. The base can be removed from the backlight module, allowing the lamp to be taken out and replaced independently. This extraction eliminates the need to disassemble the entire backlight module or other fragile components during lamp replacement.
2Ease of repair
If the backlight module is disassembled for lamp replacement, then the damaged lamp can be replaced, but other fragile components may be damaged during disassembly
Solution Approach 1:
The lamp is separated onto an independent base that can be removed without disassembling other components. The base acts as an intermediate carrier that isolates the lamp replacement operation from other fragile components such as the diffuser plate, liquid crystal panel, and driver circuit, thereby eliminating the risk of accidental damage during replacement.
Solution Approach 2:
The lamp is extracted and mounted on a removable base that can be detached from the backlight module. This allows the lamp to be replaced by simply removing and reattaching the base, without exposing other fragile components to damage risks associated with full module disassembly.
3Productivity
If lamps are fixed in the backlight module, then the module structure is stable, but replacement time increases for maintenance
Solution Approach 1:
The lamp is mounted on a separate base that can be quickly removed and replaced without disassembling the entire backlight module. This modular approach reduces maintenance time by allowing technicians to replace lamps in minutes rather than hours, significantly improving productivity for LCD devices with multiple lamps.
Solution Approach 2:
The base is designed with dynamic characteristics that allow quick insertion and removal. The light source holder uses a secure but removable fastening mechanism that enables rapid lamp replacement while maintaining stability during operation, optimizing both operational stability and maintenance efficiency.
4Area of stationary object
If LCD size increases, then display capability improves, but lamp replacement becomes increasingly difficult
Solution Approach 1:
The lamp replacement operation is segmented into a modular base unit that can be handled independently regardless of LCD size. This allows technicians to work with a small, manageable replacement unit even when replacing lamps in large-format displays, maintaining ease of operation across different display sizes.
Solution Approach 2:
The lamp is extracted onto a removable base that can be handled and replaced as a single unit. This extraction approach makes lamp replacement equally simple for both small and large LCD displays, eliminating the increased difficulty that would otherwise accompany larger display sizes.

AI summary
The present invention provides a backlight module used for a liquid crystal display. The backlight comprises a back plate having a first track set, a detachable light source set disposed on the back plate, and an optical films set combined with the back plate. The detachable light source set comprises a base, a light source disposed on a first side of the base, and a second track set disposed on a second side of the base. The second track set can connect to and slide on the first track set. Then the detachable light source set is removable, and the light source is easily to be replaced.
