Sliding Display Panel With Modular Joints And Dummy Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices, such as OLED and LCDs, lack the ability to efficiently expand or contract their display area without compromising structural integrity or increasing complexity, limiting their form factor and usability in flexible electronic devices.
Innovation Solution
A slidable display device design featuring a display panel with active and dummy areas, supported by a modular joint system and fixing tools, allowing for flexible bending and expansion while maintaining structural stability through a support module and panel storage container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a display device uses a fixed rigid structure, then structural integrity is maintained, but the display area cannot be expanded or contracted
Solution Approach 1:
The display panel is divided into multiple active areas (first, second, third active areas) and dummy areas that can slide relative to each other. The joint part includes multiple joints spaced apart in the first direction, creating modular segments that can move independently while maintaining overall structural integrity.
Solution Approach 2:
The display device transitions from a static rigid structure to a dynamic slidable structure. The second active area and third active area can slide in the first direction relative to the first active area, allowing the display area to expand and contract dynamically while maintaining structural stability through the joint part and fixing tools.
2Area of moving object
If a display device allows flexible bending and sliding, then display area can be expanded, but structural integrity may be compromised
Solution Approach 1:
The joint part is pre-configured with multiple joints extending in the second direction and spaced apart in the first direction, creating a predetermined sliding path and structural framework. The fixing tools are pre-positioned on the dummy areas to maintain structural integrity during sliding operations, ensuring reliability while enabling area expansion.
3Stability of the object's composition
If dummy areas are used to support sliding mechanism, then structural stability is maintained, but manufacturing complexity increases
Solution Approach 1:
The dummy areas serve multiple functions: they provide structural support for the sliding mechanism, accommodate the fixing tools, and maintain structural stability during expansion and contraction. The joint part serves both as a connection element and as a guide for the sliding motion, reducing the need for separate components and simplifying manufacturing.

AI summary
A display device includes a display panel including a first active area, a second active area configured to slide in the first direction, a third active area configured to slide in the first direction, a first dummy area, and a second dummy area. A plurality of joints extend in a second direction intersecting the first direction, are spaced apart from each other in the first direction, are attached to a bottom surface of the display panel, and overlap the second active area, the third active area, the first dummy area, and the second dummy area. A first fixing tool and a second fixing tool are disposed on the first and second dummy area of the display panel, respectively, and are configured to assist a sliding behavior of the display panel.
