Solution Overview
Problem
Current flexible displays have a single display mode and limited user experience due to their fixed curvature, restricting their application and usability.
Innovation Solution
A flexible display device with a rigid portion and a flexible display portion that can be connected to form a ring structure, allowing for two display modes - unfolded and folded states, with the rigid portion protecting the circuit board and the flexible portion bending to form a cylindrical surface, enabling versatile display options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flexible display screen is fixed on a certain curvature arc, then the structural stability is improved, but the display mode becomes single and user experience is reduced
Solution Approach 1:
The patent applies the dynamics principle by enabling the flexible display screen to transition between different states (folded and unfolded configurations). The display screen is designed with flexible connections that allow it to dynamically change its curvature and display orientation, transforming from a static fixed-curvature design to a dynamic multi-state structure. This resolves the contradiction by maintaining structural stability through defined connection mechanisms while enabling multiple display modes through state transitions.
Solution Approach 2:
The patent applies segmentation by dividing the display device into distinct modular components: a rigid portion containing the circuit board and a flexible display portion. These segments are connected through flexible connections that allow relative movement. This modular segmentation enables the display screen to be configured in different arrangements (folded or unfolded) while maintaining structural integrity, thereby providing multiple display modes without compromising stability.
2Adaptability or versatility
If the flexible display screen is made bendable to form ring structure, then the versatility and user experience are improved, but the circuit board protection becomes compromised
Solution Approach 1:
The patent applies segmentation by separating the device into a rigid portion (housing the circuit board) and a flexible display portion. This physical separation allows the display screen to bend and form ring structures while the circuit board remains protected within the rigid portion. The flexible connections between segments transmit necessary signals while isolating the circuit board from mechanical stress, thus maintaining both versatility and reliability.
Solution Approach 2:
The patent applies local quality by assigning different mechanical properties to different parts of the device. The rigid portion maintains high stiffness to protect the circuit board, while the flexible display portion is designed with high flexibility to enable bending and multiple configurations. This localized differentiation of mechanical properties allows the system to achieve both circuit board protection and display versatility simultaneously.
3Reliability
If the rigid portion and flexible display portion are connected with connecting members, then the structural reliability is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by using discrete connecting members (such as hinges or flexible connectors) to join the rigid portion and flexible display portion. These connection elements are designed as independent modules that provide reliable mechanical coupling while allowing controlled movement. This segmented connection approach enhances reliability through dedicated connection mechanisms while managing complexity by using standardized, modular components rather than integrated complex structures.

AI summary
Disclosed is a flexible display device, comprising a rigid portion, in which a circuit board is provided; a flexible display portion, displaying an image. The circuit board is electrically connected with the flexible display portion. The flexible display portion comprises a first end and a second end, which are oppositely arranged, the first end is rotatably connected with one end of the rigid portion, the second end is provided with a first connecting member, and an end of the rigid portion away from the first end is provided with a second connecting member to cooperate with the first connecting member, and as the first connecting member is connected with the second connecting member, the rigid portion is connected to the flexible display portion end to end to form a ring structure. It is advantageous to switch between the unfolded state and the folded state of the flexible display device.
