Folder-Type Flexible Display Hinge for Portable Large Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face a trade-off between large screen size and portability, as increasing the display size leads to a proportional increase in housing size, limiting the expansion of the display area and reducing portability.
Innovation Solution
A flexible display device with a foldable design that includes a hinge unit and a multi-bar mechanism, allowing the display to be deflected and folded, thereby maximizing the display area while maintaining portability.

If the display size is increased to achieve a large screen, then the display area is improved, but the housing size increases proportionally which reduces portability
Solution Approach 1:
The housing is divided into a first housing and a second housing that can be folded relative to each other via a hinge unit. This segmentation allows the display to be folded into a compact form for portability while maintaining a large unfolded display area, effectively resolving the contradiction between large screen size and portability.
Solution Approach 2:
The housing transitions from a static structure to a dynamic foldable structure. The hinge unit enables the housing to change its configuration between unfolded (large display area) and folded (compact portable form), allowing the device to adapt between maximizing display area and maximizing portability based on usage context.
2Area of stationary object
If the display is made foldable to maximize display area expansion, then the display area is improved, but the folding section experiences increased fatigue which reduces durability
Solution Approach 1:
The display is segmented into a first display area on the first housing and a second display area on the second housing, with a hinge unit connecting them. This segmentation allows the folding mechanism to be distributed across the hinge structure rather than concentrated at a single point, reducing stress and fatigue at any one location while enabling large display area expansion.

AI summary
A portable electronic device is provided. The portable electronic device includes a first housing including a first surface and a second surface a second housing including a third surface and a fourth surface, and a hinge. The hinge includes a hinge shaft, a sliding device including a portion configured to slide to an inside or an outside of the second housing to be introduced, or slide from the inside or the outside of the second housing in a specific direction to be extracted in correspondence to a hinge operation of the second housing, and a multi-bar disposed between the first surface and the fourth surface and including multi-bar units to be spread or bent in correspondence to a hinge operation of the second housing.
