Display Device Bottom Chassis Binding Groove for Slim Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display device design is to maintain strength while achieving a slim bezel, as the reduced space can compromise the structural integrity due to insufficient room for the display panel and optical sheet.
Innovation Solution
A display device with a bottom chassis featuring a binding portion and a mold frame that controls the position of the display panel and optical sheet, including a binding groove and stopper portion, which enhances stability and supports the components effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the bezel width is reduced to achieve a slim profile, then the aesthetic appearance and thinness are improved, but the space available to receive the display panel and optical sheet is insufficient, causing the structural strength to decrease
Solution Approach 1:
The binding structure is divided into multiple functional parts: a binding portion with a panel seating part and stopper portion for securing the display panel, and a separate mold frame with a binding groove for receiving the bottom chassis. This segmentation allows each component to be optimized independently for both slimness and strength.
Solution Approach 2:
The display panel and optical sheet are nested within the bottom chassis, which is in turn received by the mold frame. The binding portion is positioned within the binding groove, creating a nested arrangement that maximizes space utilization while maintaining structural integrity despite the reduced bezel width.
2Shape
If the bezel width is reduced to achieve a slim profile, then the aesthetic appearance and thinness are improved, but the space available to receive the display panel and optical sheet is insufficient, causing the stability to decrease
Solution Approach 1:
The binding groove is pre-formed in the mold frame at the appropriate position and orientation, and the binding portion is pre-configured with the panel seating part and stopper portion. This preliminary preparation ensures that when assembled, the display panel and optical sheet are securely positioned without requiring additional support structures that would increase the bezel width.
3Strength
If the binding portion and mold frame structure are added to secure the display panel, then the strength and stability are improved, but the device complexity increases
Solution Approach 1:
The mold frame serves multiple functions: it provides the outer structural boundary, contains the binding groove for receiving the binding portion, and supports the overall assembly. The binding portion simultaneously secures the display panel through its panel seating part and provides structural reinforcement through its integration with the mold frame. This multi-functionality reduces the need for separate components.
Solution Approach 2:
The binding portion and mold frame are designed to work together as an integrated binding structure. The panel seating part and stopper portion of the binding portion combine to form a complete securing mechanism within the binding groove, eliminating the need for separate fastening components and reducing overall structural complexity.
