Backlight Module Lamp Supporter Inversion for Light Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight modules have suboptimal light emission due to the base substrate of the lamp supporter obstructing the reflector, and the complexity of fabricating a trench to accommodate the substrate complicates miniaturization.
Innovation Solution
The lamps and base substrate of the lamp supporter are positioned on opposite sides of the back cover, allowing the reflector to be flatly adhered, which enhances light emission and simplifies the back cover's fabrication by eliminating the need for a trench, enabling miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base substrate of the lamp supporter is disposed on the back cover to support the lamps, then the lamps can be held in position, but the base substrate shields part of the reflector and reduces light emission efficiency
Solution Approach 1:
The lamp supporter base substrate is moved from the inner side of the back cover to the outer side, utilizing the third dimension (depth/thickness) to resolve the spatial conflict between the base substrate and reflector. This dimensional relocation allows both components to coexist without mutual obstruction, maintaining lamp positioning stability while eliminating light shielding.
Solution Approach 2:
Instead of placing the base substrate on the conventional side (inner side of back cover), the invention inverts the arrangement by positioning it on the outer side. This inversion resolves the contradiction by reversing the spatial relationship between the base substrate and reflector, allowing the reflector to function fully without being shielded.
2Shape
If a trench is formed on the back cover to accommodate the base substrate, then the reflector can be disposed on a planar surface, but the fabrication process becomes more complex
Solution Approach 1:
The base substrate is extracted from the back cover structure and relocated to the outer side. This extraction eliminates the need to form a trench in the back cover, maintaining reflector surface planarity while significantly simplifying the fabrication process by removing the additional machining step.
Solution Approach 2:
Instead of modifying the back cover by creating a trench (in-plane modification), the solution moves the base substrate to another dimension (outer side of the back cover). This dimensional relocation achieves reflector surface planarity without requiring complex back cover fabrication.
3Volume of moving object
If the base substrate is disposed within the back cover, then the structure is compact, but the backlight module cannot be miniaturized due to increased thickness
Solution Approach 1:
The base substrate is inverted from an internal position within the back cover to an external position on the outer side. This inversion reorganizes the spatial arrangement, allowing the backlight module to be miniaturized by reducing the thickness occupied by the base substrate while maintaining structural compactness through optimized component layout.
Solution Approach 2:
The base substrate is relocated from the internal dimension (within back cover thickness) to the external dimension (outer side of back cover). This dimensional change enables backlight module miniaturization by freeing up thickness space while maintaining structural integrity and compactness through alternative spatial organization.

AI summary
A backlight module including a back cover, a reflector, a lamp supporter, and a number of lamps is provided. The back cover includes a number of holes, an inner face, and an outer face. The reflector is disposed on the inner face and has a number of openings. The openings expose parts of the holes. The lamp supporter has a base substrate and a number of carriers that are connected to the base substrate. The base substrate is assembled to the outer face of the back cover, and the carriers penetrate the holes of the back cover and the openings of the reflector. The lamps are disposed in the carriers, such that the lamps and the base substrate are located at two opposite sides of the back cover.
