Solution Overview
Problem
Existing thin Mini LED backlight modules face challenges with high manufacturing costs and complex assembly processes, including deformation or breakage of reflective sheets and the need for screws that affect appearance and convenience.
Innovation Solution
A backlight module design featuring a housing with a backplate, sidewall, and panel mounting platform forming a concavity, supported by a supporting member with a reflective incline structure, allowing for simplified assembly and omission of front frame components, reducing the area and complexity of the reflective sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If aluminum extruded front frame is used, then structural support is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent removes the aluminum extruded front frame from the backlight module structure. Instead, it uses a simplified housing with a backplate, sidewall, and panel mounting platform that integrates the support function. The reflective sheet is bent to form a reflective slope that extends to the housing edge, eliminating the need for a separate front frame structure.
Solution Approach 2:
The patent combines multiple functions into the housing structure. The backplate, sidewall, and panel mounting platform are integrated into a single housing component that provides both structural support and mounting functionality. The reflective sheet serves dual purposes as both a light reflector and a structural element that extends to the housing edge.
2Illumination intensity
If reflective sheet is bent to form reflective slope, then light reflection efficiency is improved, but risk of deformation or breakage increases
Solution Approach 1:
The reflective sheet is pre-formed with a reflective slope during manufacturing, with the slope extending directly to the edge of the housing. This preliminary formation eliminates the need for field bending or complex assembly operations that could cause deformation or breakage. The sheet is designed to fit the housing geometry from the outset.
Solution Approach 2:
Instead of bending the reflective sheet upward to create a slope, the patent extends the reflective sheet horizontally to the housing edge and forms the slope in a manner that reduces stress concentration. The reflective slope is integrated with the housing structure rather than being a separate bent component.
3Stability of the object's composition
If screws are used to lock the frame, then structural stability is improved, but appearance quality and assembly convenience deteriorate
Solution Approach 1:
The patent removes screws and other visible fastening components from the front frame structure. The housing is designed to provide structural stability through its integrated backplate, sidewall, and panel mounting platform configuration, eliminating the need for external screw fastening that would compromise appearance and assembly convenience.
4Strength
If front frame components are included, then structural completeness is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the functions of the backplate, sidewall, panel mounting platform, and support structures into a single integrated housing component. This consolidation eliminates the need for separate front frame parts and reduces the total number of components, thereby lowering manufacturing costs while maintaining structural completeness.
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously provides structural support, light reflection housing, panel mounting, and edge support functions. This universal design replaces multiple specialized components (front frame, backplate, mounting brackets) with a single versatile housing structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies assembly, reduces manufacturing costs, and ensures uniform light distribution without the need for bending reflective sheets, enhancing the appearance and functionality of the backlight module.
Implementation Method 1
The supporting member has a reflective incline structure. The reflective incline structure is configured to directly reflect light traveling towards an inner side surface of the housing towards the diffuser plate.

AI summary
A backlight module includes a housing, a light source, at least one supporting member, a diffuser plate, and an optical film. The housing includes a backplate portion, a sidewall portion, and a panel mounting platform. The sidewall portion is arranged along a periphery of the backplate portion. The panel mounting platform is connected and bent relative to the sidewall portion, such that the panel mounting platform, the sidewall portion, and the backplate portion form a concavity. The light source is disposed on the backplate portion. The supporting member is disposed in the housing and at least partially located in the concavity. The optical film and the diffuser plate are stacked on the supporting member. The supporting member has a reflective incline structure that is configured to directly reflect light traveling towards an inner side surface of the housing towards the diffuser plate.
