Modular Backlight Housing for LCD Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing variety and size of LCD panels require continuous development of new molds for housings, leading to increased material usage, development costs, and complexity, as traditional backlight modules are not adaptable to different sizes.
Innovation Solution
A modular design for the backlight module using strip-shaped or L-shaped housing unit structures that can be adjusted and assembled into a housing, with buffering strips to prevent light leakage, allowing for various sizes without the need for multiple molds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional housings are designed for different LCD panel sizes, then each size can be accommodated, but new molds must be continuously developed, increasing material usage, development cost, and time
Solution Approach 1:
The housing is divided into multiple standardized housing units that can be selectively assembled. Each housing unit has a standardized structure with features for connecting to adjacent units, allowing the same basic housing unit design to be configured for different panel sizes by varying the number and arrangement of units, thereby eliminating the need for different molds for each size
Solution Approach 2:
A universal housing unit design is created that can serve multiple functions across different product sizes. The standardized housing units can be used universally for various LCD panel dimensions through selective assembly, making one housing design serve multiple size requirements that previously needed separate dedicated designs
2Area of stationary object
If housing size increases to accommodate larger LCD panels, then larger displays are supported, but material usage and manufacturing complexity increase
Solution Approach 1:
Instead of creating one large housing for bigger panels, the housing is segmented into multiple standardized units that are assembled together. This allows the housing area to scale with panel size while using the same basic unit design, preventing excessive material usage that would occur with custom-large housings and enabling efficient material utilization through standardized unit production
3Adaptability or versatility
If continuous new mold development occurs for different housing sizes, then all panel sizes can be supported, but development cost and time increase
Solution Approach 1:
A universal housing unit design is created that can serve multiple functions across different product sizes. The standardized housing units can be used universally for various LCD panel dimensions through selective assembly, making one housing design serve multiple size requirements that previously needed separate dedicated designs
Solution Approach 2:
The housing system transitions from static, size-specific designs to a dynamic, configurable assembly system. The same standardized housing units can be dynamically configured in different numbers and arrangements to match different panel sizes, allowing the housing configuration to adapt flexibly to various requirements without retooling

AI summary
The present invention provides a backlight module and a housing unit structure thereof. The backlight module includes a back plate having a first edge, a second edge, a third edge and a fourth edge. The edges of the back plate are provided with a housing including a plurality of housing unit structures. The housing unit structures have a strip shape or an L-shape, respectively, and are disposed on the back plate by connecting or spacing a distance to each others to assemble into a housing. The backlight module uses an adjustable modular design to adjust the number of the housing unit structures for being suitably applied to various backlight modules with different sizes. Except for reducing the use of material, the development cost and time of the backlight module can be saved.
