Display Panel Frame Protrusions for Smaller Bezels and Stronger Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in minimizing the bezel area and ensuring strong component bonding to enhance durability.
Innovation Solution
The display device incorporates a frame with protrusions and a molding member that seals and bonds with the display components, minimizing the bezel area and improving bonding strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cover unit is disposed below the cover window to protect display components, then protection of components is improved, but the bezel area increases due to required spacing
Solution Approach 1:
The patent merges the protective cover unit function with the frame structure by integrating the frame into the protective assembly. The frame is disposed below the display panel and extends to provide protection, eliminating the need for a separate cover unit and reducing the bezel area while maintaining component protection.
Solution Approach 2:
The frame serves multiple functions simultaneously: it provides structural support, protects the display components, and minimizes the bezel area. By making the frame multi-functional, the patent eliminates the need for additional protective components that would increase the bezel size.
2Strength
If conventional bonding methods are used between components, then manufacturing is simpler, but bonding strength is insufficient leading to component separation
Solution Approach 1:
The patent divides the bonding interface into multiple segments by providing protrusions on the frame that contact the molding member at multiple discrete points. This segmentation of the bonding interface increases overall bonding strength while maintaining relatively simple manufacturing processes.
Solution Approach 2:
The patent adds a dimensional feature (protrusions) to the frame structure that extends into the bonding interface. This dimensional change creates multiple contact points between the frame and molding member, significantly improving bonding strength without complicating the basic assembly process.

AI summary
A display device includes a cover window; a display panel which includes an active area disposed below the cover window and including a plurality of pixels disposed therein, a first non-active area which encloses the active area, and a bending area which extends from one side of the first non-active area to be bent; a frame which is disposed below the display panel and includes a plurality of protrusions disposed on a side surface; and a molding member which is disposed below the cover window along an end of the cover window and is disposed so as to cover a side surface of the display panel, a side surface of the frame in which the plurality of protrusions is disposed, and a part of a bottom surface of the frame.
