Back Plate Groove Layout for Thinner LCD Module Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display devices are thick and costly due to their complex structure and high component count, particularly in the backlight module.
Innovation Solution
The display device incorporates a back plate with a groove body that houses the circuit board, reducing the number of components and thickness by integrating the circuit board directly into the groove, and employs an integrally formed back plate and bracket to simplify assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the backlight module uses a complex structure with multiple components, then the functional requirements are met, but the display device thickness increases and processing cost increases
Solution Approach 1:
The circuit board is integrated into the groove body structure, merging two separate components (circuit board and groove body) into a unified structure. This reduces the number of discrete parts and eliminates the need for separate mounting, thereby reducing overall thickness while maintaining all necessary functions
Solution Approach 2:
The groove body is designed to serve multiple functions: it provides structural support, houses the circuit board, and defines the spatial relationship between components. This multi-functionality reduces the need for additional separate components, thereby reducing thickness without compromising functional requirements
2Reliability
If the backlight module uses a complex structure with multiple components, then the functional requirements are met, but the processing and assembly cost increases
Solution Approach 1:
By combining the circuit board and groove body into an integrated structure, the number of manufacturing steps is reduced. Instead of producing separate components and then assembling them, the integrated design allows for fewer production steps, lower material handling costs, and simplified quality control, thereby reducing processing and assembly costs
3Ease of operation
If the circuit board is disposed outside the groove body, then the assembly is simpler, but the display device thickness increases
Solution Approach 1:
The circuit board is nested within the groove body structure, similar to how nested dolls fit inside each other. This nesting arrangement allows the circuit board to be contained within the existing structural envelope of the groove body, thereby reducing overall thickness while maintaining assembly simplicity through the pre-designed groove geometry
