Retractable Display Device with Rotating Shaft and Movable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medium-sized and large-sized OLED display devices occupy a large area and are limited to single application scenarios, necessitating a solution to enhance their spatial efficiency and versatility.
Innovation Solution
A display device design featuring a housing with a rotating shaft and a display module that includes multiple display portions and a non-display portion, allowing the display area to be adjusted by winding the non-display portion around the rotating shaft, thereby reducing the occupied space while maintaining a multi-sided display function.

1Area of moving object
If a medium-sized or large-sized OLED display device is used, then the display area is large, but the occupied space is large and the application scenario is single
Solution Approach 1:
The display module is designed to be movable relative to the housing through a driving assembly, allowing it to transition between extended and retracted positions. This dynamic configuration enables the display area to be adjusted while maintaining a compact form factor when retracted, thus resolving the contradiction between large display area and small occupied space.
Solution Approach 2:
The display module is segmented into multiple display portions that can be independently positioned. By dividing the display into segments that can be selectively extended or retracted, the system achieves flexible configuration of display area while controlling the overall occupied space, addressing both requirements simultaneously.
2Area of moving object
If a medium-sized or large-sized OLED display device is used, then the display area is large, but the application scenario is limited to single use
Solution Approach 1:
The display device is designed with multi-functionality to serve various application scenarios. The movable display module can be configured for different display areas and orientations, enabling the same device to be used in diverse applications such as entertainment, education, and information display, thus expanding the application scenario beyond single-use limitations.
Solution Approach 2:
The dynamic adjustment capability of the display module allows the device to adapt to different application requirements by changing display area and configuration. This versatility enables the device to serve multiple purposes across different scenarios, resolving the limitation of single application scenario.
