Display Device Fixing Structure for Enlarged Panel Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with large display areas face challenges in maintaining productivity and strength due to the use of mold frames, which can lead to breakage from external impacts and decreased panel size when using tapes without hooks for attachment.
Innovation Solution
A display device structure featuring a first fixing member with panel guide portions and flanges, coupled with a second fixing member having a side wall portion that is bent and inserted into a recess, minimizing the occupied space while ensuring secure coupling and protection from impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a mold frame is used to retain the LCD panel, then the panel strength is improved, but the display area is decreased and productivity is reduced
Solution Approach 1:
The fixing structure is divided into multiple components: a first fixing member with panel guide portions and flanges, and a second fixing member with receiving members. This segmentation allows the fixing function to be distributed across multiple smaller elements rather than requiring a single large mold frame, thereby preserving display area while maintaining panel strength through the distributed fixing points.
Solution Approach 2:
The first fixing member is nested within or coupled to the second fixing member, with the flange of the first fixing member inserted into the receiving member of the second fixing member. This nested configuration allows the fixing members to be compactly arranged, minimizing the space they occupy around the LCD panel and maximizing the display area while still providing adequate structural support.
2Device complexity
If a tape without hooks is used to attach the LCD panel to the mold frame, then the manufacturing complexity is reduced, but the panel strength and productivity are decreased
Solution Approach 1:
The first fixing member incorporates a flange that extends from the body portion, creating a flexible yet structurally sound attachment element. This flange can be简单地 formed by bending the fixing member material, providing a hook-like structure without requiring complex molding processes, thus maintaining manufacturing simplicity while significantly improving panel attachment strength.
3Productivity
If the fixing member structure is simplified, then the productivity is improved, but the ability to protect from external impacts is reduced
Solution Approach 1:
The panel guide portions and flanges are pre-formed on the first fixing member, and the receiving members are pre-formed on the second fixing member. This preliminary structuring allows for rapid assembly without requiring complex impact protection measures to be added later, thereby maintaining high productivity while ensuring the panel is adequately protected from external impacts through the pre-configured fixing structure.

AI summary
There is provided a display device with an enlarged display area. The display device includes a panel unit for displaying an image, a first fixing member receiving the panel unit, and a second fixing member coupled to the first fixing member. A flange extending from an edge of a body portion of the first fixing member in a direction parallel to the body portion is coupled to a receiving member formed in the second fixing member.
