Foldable Flexible Substrate Display Assembly for Large Screen Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional AMOLED screens face limitations in size and portability, making it difficult to achieve a balance between a large display area and convenient hand operation in mobile devices.
Innovation Solution
A display assembly using a flexible substrate with a first and second display device, where the second display device is partially foldable, connected by a metal wire, allowing for internal folding to increase display area while maintaining portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the mobile phone screen is made larger, then the display area is increased, but the portability and hand operation convenience deteriorate
Solution Approach 1:
The patent applies the dynamics principle by making the display device foldable, allowing it to transition between a compact folded state for portability and an expanded unfolded state for larger display area. The flexible substrate and foldable structure enable the display to dynamically change its configuration based on usage needs, resolving the contradiction between large display area and hand operation convenience.
Solution Approach 2:
The patent implements the nested doll principle by folding the second display device partially over itself, with the first display section overlapping the second display section in the folded state. This nesting approach allows the large display area to be compacted into a smaller form factor that can be easily held and operated, while still providing the full display area when unfolded.
2Area of stationary object
If the mobile phone screen is made larger, then the display area is increased, but the portability deteriorates
Solution Approach 1:
The flexible and foldable design allows the display device to dynamically adjust its size, providing a large display area when needed while maintaining a compact form factor for portability. The ability to fold the display reduces the effective size and weight perception during carrying, resolving the contradiction between large display area and portability.
3Speed
If conventional AMOLED screens are used, then the response time and contrast are improved, but the size is limited and product life is shorter
Solution Approach 1:
The patent employs flexible substrates and thin film structures that enable the AMOLED display to be folded without compromising the fast response time and high contrast characteristics. The flexible material allows the screen to achieve larger effective display areas through folding while maintaining the performance benefits of AMOLED technology.

AI summary
A display assembly includes a flexible substrate comprising a first section, a connecting section and a second section. A first display device is disposed on the first section. A second display device is disposed on the second section. The second display device comprises a first display section, a foldable section and a second display section connecting with one another in sequence. A metal wire disposed in the connecting section of the flexible substrate is electrically connected to the first display section and the first display device.
