Flexible Display Device Sliding Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible OLED display devices are inconvenient to touch and control when hand-held due to their softness, which affects portability and usability.
Innovation Solution
A flexible display device with a supporting base comprising slidably connected first and second sliding bases, a flexible display screen with integrally formed parts, and a flexible supporting plate that allows the screen to be supported and easily switched between folded and unfolded states, enhancing touch control and reducing dents during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display screen is made soft and flexible, then it can be rolled up to improve portability, but it becomes inconvenient to touch and control when hand-held
Solution Approach 1:
The supporting base is divided into a first sliding base and a second sliding base that can move relative to each other. This segmentation allows the device to transition between a compact rolled state for portability and an extended state that provides a stable, rigid support surface for easy touch control when hand-held.
Solution Approach 2:
The supporting base incorporates sliding connections between the first and second sliding bases, enabling dynamic transformation between different structural states. The connecting part allows the transition to be smooth and controllable, providing both compactness for carrying and stability for use.
2Volume of moving object
If the flexible display screen is rolled up to reduce space occupation, then portability is improved, but the display area is reduced
Solution Approach 1:
The flexible display screen is segmented into a first part, second part, and connecting part that can be independently positioned. When rolled up, the segments are compacted to minimize volume. When extended, the segments are unfolded to maximize display area, providing both compact storage and large viewing area capabilities.
Solution Approach 2:
The flexible display screen can be nested or rolled up into a compact form factor for storage and transport, similar to nested dolls. When needed for use, it can be unrolled to expand the display area, providing both small footprint for portability and large area for functionality.
3Adaptability or versatility
If the flexible display screen is made flexible and bendable, then it can be rolled up, but it becomes dented when touched
Solution Approach 1:
The supporting base acts as an intermediary structure between the user's hand and the flexible display screen. When the user touches the screen, the supporting base provides a rigid support that prevents direct compression and denting of the flexible display screen, while still allowing the screen to remain flexible for rolling.
Solution Approach 2:
The supporting base is segmented into sliding bases that can move independently. This segmentation allows the support structure to adapt to the flexible display screen's movements while maintaining rigid support points that prevent denting during touch interaction.

AI summary
The present application discloses a flexible display device, including: a supporting base, wherein the supporting base includes a first sliding base and a second sliding base, and a flexible display screen, wherein the flexible display screen includes a first part, a second part, and a connecting part connecting the first part with the second part. The first part is fixedly connected to the first sliding base, and the second part is slidably connected to the second sliding base along a first direction. The first sliding base and the second sliding base are slid in opposite directions along the first direction, thereby changing a length of the connecting part along the first direction.
