LCD Panel Attachment to Light Guide Plate Without Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD devices have increased thickness and manufacturing complexity due to the frame structure, which isolates the liquid crystal panel from the backlight module and complicates the assembly process, thereby increasing costs.
Innovation Solution
The LCD device design eliminates the frame by directly attaching the liquid crystal panel to the light guide plate of the backlight module using blocks with concavo-convex shapes and flexible materials, allowing for a more compact assembly without the need for a frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a frame structure is used to accommodate the liquid crystal panel and backlight module, then the structural stability is improved, but the device thickness increases and manufacturing complexity increases
Solution Approach 1:
The patent combines the frame structure with the backlight module by integrating the liquid crystal panel directly onto the light guide plate, eliminating the need for a separate frame. The backlight module's frame serves dual purposes: supporting both the light guide plate and the liquid crystal panel, thereby reducing overall device thickness while maintaining structural stability.
Solution Approach 2:
The liquid crystal panel is nested directly onto the light guide plate without requiring a separate frame structure. The backlight module's frame encompasses both components, creating a nested arrangement where the liquid crystal panel is positioned within the same structural envelope as the backlight module, reducing the need for additional accommodating spaces.
2Strength
If a frame structure with supporting plate is used to accommodate both modules, then the structural support is improved, but the manufacturing process becomes complicated and cost increases
Solution Approach 1:
The patent merges the supporting functions into a single integrated frame structure that supports both the backlight module and liquid crystal panel simultaneously. The frame includes positioning protrusions that engage with corresponding recesses in both modules, providing structural support while simplifying the manufacturing process by eliminating the need for separate accommodating structures.
Solution Approach 2:
The frame structure serves multiple functions: it supports the backlight module, supports the liquid crystal panel, provides positioning through protrusions and recesses, and maintains the relative positioning between both modules. This multi-functional design reduces manufacturing complexity by eliminating the need for separate accommodating plates and fastening mechanisms.
