Integrated Back Plate with Bent Structures for LCD Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display (LCD) backlight modules have complex and costly structures due to numerous housing strips, leading to increased material management complexity and manufacturing costs, as well as instability during installation.
Innovation Solution
The design incorporates a back plate with bent structures that replace traditional housing strips, integrating support functions for the optical film assembly and reflective sheet, simplifying the module structure and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional separate-type housing strips are used to construct the backlight module, then the structural stability during installation is improved, but the device complexity and manufacturing cost are increased
Solution Approach 1:
The patent merges the back plate and housing strips into a single integrated back plate structure. The back plate includes a main body portion and multiple bent structures that extend from the main body to form housing strips, eliminating the need for separate housing strip components while maintaining structural stability during installation.
Solution Approach 2:
The back plate is designed to perform multiple functions: it serves as both the back plate and the housing strips simultaneously. The bent structures extend from the main body portion to form housing strips that can accommodate optical film assemblies of different types and sizes, reducing the need for multiple specialized components.
2Adaptability or versatility
If multiple housing strips with different sizes are used for various LCD panels, then the adaptability to different panel types is improved, but the manufacturing cost and material management complexity are increased
Solution Approach 1:
The back plate is designed as a universal component that can accommodate optical film assemblies of different types and sizes. The bent structures can be configured to match various panel dimensions, eliminating the need to develop new molds for each panel type while maintaining adaptability.
Solution Approach 2:
The design allows for parameter changes in the bent structures (such as length, angle, and position) to accommodate different LCD panel specifications. This flexibility enables a single back plate design to serve multiple panel types without requiring complete redesign or new molds for each variation.
3Strength
If conventional separate housing strips are used, then the structural support for optical film assembly is improved, but the material usage and manufacturing cost are increased
Solution Approach 1:
The back plate and housing strips are merged into a single integrated structure. The bent structures extend from the main body portion to provide support, eliminating the need for separate housing strip materials while maintaining the necessary support capability for optical film assemblies.
