Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face a challenge in achieving both high portability and high browsability, as enlarging display regions for better data display often compromises portability in portable devices.
Innovation Solution
An electronic device with a flexible display panel that includes a first and second support body connected by a hinge, allowing the panel to be rotated and folded, maintaining a seamless large display region while being compact and portable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display region is enlarged to improve browsability, then the display area increases, but the device size and weight increase, reducing portability
Solution Approach 1:
The display device is divided into multiple segments that can be folded relative to each other. The display panel is segmented into first and second display regions connected by a folding hinge, allowing the large display area to be divided into portable sections that can be collapsed together.
Solution Approach 2:
The first and second display regions are designed to nest within each other when folded, with one display region containing or overlapping the other in the folded state, similar to nested dolls. This allows the large display area to be compacted into a small portable form factor.
2Area of moving object
If the display region is enlarged to improve browsability, then the display area increases, but the device volume increases, reducing portability
Solution Approach 1:
The display device is divided into multiple segments that can be folded relative to each other. The display panel is segmented into first and second display regions connected by a folding hinge, allowing the large display area to be divided into portable sections that can be collapsed together.
Solution Approach 2:
The display device transitions from a two-dimensional flat structure to a three-dimensional folded structure. By utilizing the folding dimension, the large display area is collapsed along the folding axis, reducing the device volume while maintaining the full display area when unfolded.
3Weight of moving object
If a flexible display panel is used to enable folding, then portability is improved, but the structural complexity increases
Solution Approach 1:
The display device employs a flexible display panel that can be bent and folded without breaking. The flexible panel includes a flexible substrate and functional layers formed thereon, replacing rigid display structures with flexible thin-film construction to enable folding capability.
Solution Approach 2:
The display device transitions from a static rigid structure to a dynamic flexible structure. The display panel and support bodies are designed to dynamically change configuration between unfolded and folded states, with the flexible materials and hinge mechanisms enabling controlled movement and deformation.

AI summary
Provided is an electronic device with high portability and/or high browsability. The electronic device includes first and second support bodies, a first hinge, and a flexible display panel. The first hinge has a first rotation axis and connects the first and second support bodies to each other, and the first and second support bodies are capable of relatively rotating on the first rotation axis. The display panel includes at least first and second portions supported by the first and second support bodies, respectively; the first rotation axis and a first plane including the display surface overlapping with the first portion or a second plane including the display surface overlapping with the second portion are parallel to each other; and each of a distance between the first rotation axis and the first plane or the second plane is greater than zero.
