Backlight Module Uniform Light Emission via Edge-Mounted LED Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight modules suffer from non-uniform light emission due to the placement of LED strips, where only the longest edge emits light, leading to inefficiencies in light distribution.
Innovation Solution
A backlight module design featuring a module substrate with integrated power supply lines and mounting regions, allowing for the placement of light emitting source assemblies on multiple edges, ensuring uniform light emission through adjustable and detachable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED strips are arranged on the base substrate to form a straight LED strip, then the LED strip is protected from bending damage, but only the longest edge emits light while other edges do not, leading to non-uniform light emission
Solution Approach 1:
The backlight module divides the light emitting source into multiple independent LED strips that can be separately arranged on different edges of the module substrate. Each LED strip is independently mounted and connected, allowing light to be emitted from multiple edges simultaneously, thus achieving uniform light distribution while protecting each strip from bending damage.
2Ease of manufacture
If the longest straight edge is selected as the edge close to which the LED strip is placed, then the LED strip is protected from bending, but the rest edges do not emit light, resulting in less uniform light emission
Solution Approach 1:
The module substrate is designed with multiple mounting regions that can accommodate LED strips on all edges, not just the longest edge. This multi-functional design allows the same substrate structure to support LED strips on any edge, enabling uniform light emission from all edges while maintaining ease of manufacture through standardized mounting interfaces.
3Stability of the object's composition
If LED strips are fixed on the base substrate, then the structure is stable, but the light emission is non-uniform and the design is not adaptable to different display device shapes
Solution Approach 1:
The mounting regions on the module substrate are designed to accommodate LED strips in flexible configurations. The LED strips can be positioned on different edges depending on the required display device shape, while maintaining stable electrical and mechanical connections. This dynamic adaptability allows the same backlight module structure to serve multiple display device configurations.
