Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving high portability, browsability, and reliability while also being able to display along a curved surface and having low power consumption.
Innovation Solution
A display device comprising a first display panel and a second display panel, where the second panel includes a visible-light-transmitting region adjacent to its display region, allowing for overlap and variable area configuration, enhancing portability and browsability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display region is increased to improve browsability, then the amount of information displayed increases, but the portability decreases
Solution Approach 1:
The display device is divided into multiple independent display panels that can be separated and folded. Each panel can be independently manufactured and handled, allowing the overall display area to be large when unfolded while maintaining compact portability when folded. The panels are connected via flexible connection regions that enable folding without compromising display integrity.
Solution Approach 2:
The display panels are arranged in a nested folding configuration where multiple panels can be stacked and stored in a compact form factor. When not in use, the panels can be folded into each other like nested dolls, significantly reducing the overall device size and weight for portable storage while maintaining the capability to expand to a large display area when needed.
2Area of stationary object
If multiple display panels are used to increase display area, then browsability improves, but device complexity increases
Solution Approach 1:
Multiple display panels are merged into a unified display system with coordinated control. The panels share common control circuits and can be managed as a single logical display unit, reducing the perceived complexity despite the physical multiplication of panels. The connection regions integrate the panels electrically and mechanically, simplifying the overall system architecture.
Solution Approach 2:
The display panels are designed with universal characteristics where each panel can function independently or in combination with others. The control system can selectively activate different panel configurations based on usage requirements, providing multiple display modes (single panel, dual panel, folded, unfolded) from the same hardware architecture, thereby managing complexity through flexible functionality.
3Adaptability or versatility
If the display device is made flexible to enable curved surface display, then adaptability improves, but reliability decreases
Solution Approach 1:
The display panels utilize flexible substrate materials and thin-film construction that inherently allow bending and conforming to curved surfaces. The flexible connection regions between panels are designed with sufficient elasticity and mechanical strength to accommodate repeated folding and curvature changes without failure, maintaining reliability while enabling adaptability to various display geometries including curved surfaces.

AI summary
A display device or an electronic device with high portability and browsability is provided. A display device which includes two display panels that overlap with each other and in which the area of a portion where the two display panels overlap with each other is variable is provided. The larger the area where the two display panels overlap with each other is, the smaller the display device becomes. The first display panel includes a first region that performs display. The second display panel includes a second region that performs display, and a third region that is adjacent to the second region and transmits visible light. When the third region overlaps with the side of a surface which performs display of the first region, display can be performed using a seamless large display region.
