Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing frame assembly for liquid crystal display devices has poor support stability for the glue frame, leading to deformation under the reaction force from the liquid crystal panel, resulting in reduced flatness of the mounting surface and light leakage around the panel, which deteriorates the display quality.
Innovation Solution
A frame assembly with a backboard featuring a receiving portion and a buffer frame supported by a folded first support portion, which enhances the stability of the glue frame and reduces deformation, thereby maintaining a flat mounting surface and minimizing light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support portion is formed on the backboard to support the glue frame, then the glue frame can be supported, but the support stability is poor and the glue frame deforms under reaction force from the liquid crystal panel
Solution Approach 1:
The support portion is divided into a first support portion and a second support portion that are folded from different sides of the backboard towards each other. This segmentation allows each support portion to independently bear reaction forces, preventing the glue frame from deforming under load while maintaining support stability.
Solution Approach 2:
The support portions are folded from the backboard in a directional manner towards the center, creating a three-dimensional support structure. This dimensional change enables the support portions to resist deformation forces more effectively by distributing loads across multiple directions rather than a single flat support point.
2Ease of operation
If the glue frame is supported on the backboard, then the liquid crystal panel can be mounted, but the mounting surface flatness is reduced due to deformation
Solution Approach 1:
By dividing the support structure into multiple folded support portions, the glue frame receives distributed support that prevents localized deformation. This maintains the overall flatness of the mounting surface while still enabling the liquid crystal panel to be securely mounted.
Solution Approach 2:
The folded support portions are pre-configured to provide cushioning support to the glue frame before the liquid crystal panel is mounted. This beforehand support prevents deformation from occurring when the panel is installed, thereby maintaining mounting surface flatness.
3Ease of operation
If the glue frame deforms, then mounting is possible, but light leakage occurs around the liquid crystal panel deteriorating display quality
Solution Approach 1:
The segmented folded support portions provide distributed support that prevents glue frame deformation, thereby eliminating the gap that would cause light leakage while maintaining the ability to mount the liquid crystal panel.
Solution Approach 2:
The support structure provides beforehand cushioning to prevent deformation before it occurs, thereby preventing light leakage from occurring in the first place while still allowing for proper mounting of the liquid crystal panel.

AI summary
There are disclosed a frame assembly and liquid crystal display device for reducing leakage of light around a liquid crystal panel and improving display quality of the liquid crystal display device. The frame assembly includes a backboard in which a receiving portion is formed, a front frame mounted on the backboard around an periphery of the backboard and a buffer frame provided between the backboard and the front frame, wherein the backboard is provided with a first support portion, which is folded from a periphery of the backboard towards inside of the receiving portion so as to support the buffer frame. With the backboard of the above configuration, the support stability for the glue frame can be increased, and the deformation of the glue frame under a reaction force from the liquid crystal panel can be reduced, thereby reducing leakage of light around the liquid crystal panel and improving a display quality of the liquid crystal display device.
