Flexible Display Stacking in a Rigid Housing for Large Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen electronic devices face challenges with portability due to their large overall size, and current foldable designs often result in complex structures.
Innovation Solution
A flexible display with multiple sub-regions that can be stacked and unfolded, housed in an accommodation groove of a device housing, allowing the display to form a large-area screen without requiring a foldable device housing structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-area display is used, then display performance is improved, but overall device size increases reducing portability
Solution Approach 1:
The display panel is designed to be flexible and capable of dynamic folding/unfolding between a folded state (for portability) and an unfolded state (for large display area). This dynamic transformation allows the display to adapt between two functional states, resolving the contradiction between large display area and compact device size.
Solution Approach 2:
The flexible display panel is nested within the device housing when in the folded state, allowing the large-area display to be contained within a compact form factor. The display can be folded into the housing cavity, enabling portability while maintaining the capability for large-area display when unfolded.
2Length of moving object
If a foldable device housing structure is used, then portability is improved, but device structural complexity increases
Solution Approach 1:
The folding functionality is extracted from the device housing structure and transferred to the display panel itself. Instead of making the entire housing foldable, only the display panel is designed to be flexible and foldable, while the housing remains a conventional rigid structure. This reduces structural complexity by isolating the folding mechanism to a single component.
Solution Approach 2:
The display panel uses flexible materials and thin-film construction to enable folding capability without requiring complex mechanical hinge structures in the housing. The flexibility is achieved at the display level through advanced materials, allowing the housing to maintain a simple, conventional structure while still enabling foldable functionality.

AI summary
The present disclosure discloses an electronic device, which includes a device housing provided with an accommodation groove and a first display connected to the device housing. The first display is a flexible display having a folded state and an unfolded state, and the first display has a plurality of display sub-regions. In a case that the first display is in the folded state, the first display is accommodated in the accommodation groove, and the plurality of display sub-regions are stacked and distributed in sequence; or in a case that the first display is in the unfolded state, the first display is unfolded out of the accommodation groove, and the plurality of display sub-regions are coplanar.
