Foldable Display Housing Structure to Prevent Panel Slippage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the folding of a display apparatus with a foldable display panel, the end of the display panel may slip, causing variations in its position, which increases the non-display area and reduces the display area, and existing structures fail to prevent this slippage effectively.
Innovation Solution
The display apparatus includes a housing with a first and second housing separated by a recessed portion, where the window is fixed on the recessed portion, and a sliding second housing, along with elastic portions and adhesive members to stabilize the display module during folding, minimizing slippage and maintaining a consistent display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If a foldable display panel is used to reduce weight and thickness, then the device becomes more portable and thinner, but the display panel may slip during folding causing increased non-display area and reduced display area
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism where the housing structure can move relative to the display panel during folding. The housing includes a first housing and second housing that can slide relative to each other, allowing the housing to dynamically adjust its position to track the display panel during folding operations, thereby preventing slippage and maintaining maximum display area.
Solution Approach 2:
The patent uses an adhesive member as an intermediary element between the housing and the display panel. This adhesive member facilitates controlled movement and prevents slippage by providing friction and adhesion, allowing the housing to maintain proper positioning relative to the display panel during folding without rigid constraints.
2Reliability
If spare space is provided in the housing to receive slipped display panel, then slippage is accommodated, but the non-display area increases and display area reduces
Solution Approach 1:
Instead of providing static spare space to accommodate slippage, the patent implements a dynamic housing structure with sliding components that actively track and follow the display panel during folding. This dynamic adjustment prevents the display panel from slipping in the first place, eliminating the need for spare space and maintaining maximum display area throughout the folding range.
Solution Approach 2:
The sliding mechanism between the first housing and second housing provides continuous feedback and adjustment during folding operations. As the display panel moves during folding, the housing components slide to maintain proper alignment, creating a feedback loop that prevents slippage and ensures the display panel remains properly positioned without requiring additional spare space.
3Stability of the object's composition
If the housing structure is made rigid to prevent slippage, then positioning stability improves, but the folding mechanism becomes more complex and less flexible
Solution Approach 1:
The patent employs a dynamic housing structure with sliding components rather than a rigid fixed structure. The first housing and second housing can slide relative to each other along defined paths, providing stability during folding while maintaining structural flexibility. This dynamic design achieves positioning stability without requiring complex rigid mechanisms or multiple fastening points.
Solution Approach 2:
The housing structure incorporates flexible sliding interfaces that allow controlled movement between housing components. These sliding mechanisms provide the necessary flexibility for folding operations while maintaining structural integrity and positioning stability, avoiding the need for complex rigid frameworks or multiple connection points.

AI summary
A display apparatus includes a folding area having a folding axis extending in a first direction and a non-folding area adjacent thereto. The folding area is foldable with respect to the folding axis. The display apparatus includes a display module including an upper surface having a display surface and a lower surface having a non-display surface. A window is on the upper surface of the display module. A housing accommodates the display module and the window. The housing includes a first housing surrounding a circumference of the display module and including a recessed portion recessed towards an inside of the first housing. A circumference of the window is disposed in the recessed portion. A second housing is separated from the first housing and disposed on the lower surface of the display module. The second housing is slidable with respect to the display module when the display module is folded.
