Adjustable Backlight Module for Liquid Crystal Panel Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backlight module jigs for liquid crystal display devices are not versatile and require separate designs for different sizes of liquid crystal panels, leading to high resource consumption and costs.
Innovation Solution
A detecting accessories for liquid crystal panels comprising a backlight module with adjustable plates that can alter the emitting area, allowing the same backlight module to accommodate various panel sizes by detachably assembling adjusting plates made of aluminum, which can be fixed at different positions to adjust the emitting area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate backlight module jigs are designed for each size of liquid crystal panel, then the examination function for each panel size is ensured, but the resource consumption and cost increase significantly
Solution Approach 1:
The patent designs a universal backlight module jig that can accommodate multiple sizes of liquid crystal panels through adjustable structures. The jig includes adjustable side frames and positioning components that can be reconfigured for different panel dimensions, allowing one jig to perform the examination function for various panel sizes instead of requiring separate jigs for each size.
Solution Approach 2:
The backlight module jig is divided into modular components including adjustable side frames, positioning blocks, and detachable parts. These segmented components can be independently adjusted and reconfigured to match different panel sizes, enabling the same jig to serve multiple examination purposes without requiring a complete separate design for each panel type.
2Reliability
If separate backlight module jigs are designed for each size of liquid crystal panel, then the examination accuracy for each panel size is maintained, but the preparation cost increases
Solution Approach 1:
The patent creates a multi-functional examination jig that maintains examination accuracy across different panel sizes through precise adjustable positioning mechanisms. The universal design eliminates the need to manufacture multiple separate jigs, thereby reducing preparation costs while preserving the ability to accurately examine each panel size through controlled adjustment of the modular components.
3Adaptability or versatility
If a single backlight module is used for examining different sizes of liquid crystal panels, then the versatility is improved, but the precision of examination may be compromised
Solution Approach 1:
The patent incorporates dynamic adjustable elements in the backlight module including movable side frames, adjustable positioning blocks, and reconfigurable support structures. These dynamic components allow the single backlight module to adapt its configuration precisely to match different panel sizes and examination requirements, maintaining examination precision while achieving versatility across multiple panel types.
Solution Approach 2:
The backlight module employs locally adjustable features such as positionable light sources, adjustable diffusion plates, and configurable edge frames that can be optimized for each specific panel size being examined. This local adjustability ensures that the examination precision is maintained for each panel type while the overall system remains a versatile single-module design.

AI summary
The disclosure provides a detecting accessories of a liquid crystal panel. The detecting accessories comprises a backlight module and two adjusting plates. The backlight module comprises a bottom plate, an edge frame surrounding the bottom plate, a backlight source assembled on the bottom plate, and a diffusion plate disposed opposite to the bottom plate, and the diffusion plate covers the edge frame. Each adjusting plate comprises a carrying section and an assembling section. The two adjusting plates are disposed adjacent with each other. The assembling sections of each adjusting plates are detachably assembled on one side of the edge frame away from the bottom plate. The light of the backlight source emits outward through the diffusion plate. The carrying sections of the two adjusting plates are configured for shading an edge of the diffusion plate for changing an emitting area of the diffusion plate.
