Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face challenges in maintaining surface quality and simplifying the sliding mechanism, as indentation on the display surface and complex structures can compromise user experience and aesthetics.
Innovation Solution
A display device design featuring a display module supported by a plate with sidewalls and chain units, where pins and coupling portions facilitate rotation of a roller to change the display area, minimizing surface contact and simplifying the sliding mechanism, while maintaining the display's structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sliding mechanism is implemented to change display area, then adaptability is improved, but device complexity increases due to multiple bars and rollers
Solution Approach 1:
The display module is divided into a first display module and a second display module that can be independently positioned. The first display module remains fixed while the second display module can be slid along the first direction to change the overall display area, allowing flexible configuration without requiring a complex mechanism to move the entire display.
Solution Approach 2:
The invention extracts the sliding function from a complex multi-bar roller system and implements it through a simplified mechanism where the second display module can be independently positioned along the first direction. This separation of functions reduces the complexity of the sliding mechanism while maintaining the ability to change display area.
2Adaptability or versatility
If multiple bars and rollers are used for sliding operation, then adaptability is improved, but surface quality deteriorates due to indentation on display surface
Solution Approach 1:
The harmful rollers that cause surface indentation are completely removed from the mechanism. Instead, the second display module is positioned along the first direction using a contactless or minimal-contact guidance system, eliminating the source of surface damage while preserving the sliding functionality for area adjustment.
Solution Approach 2:
An intermediary guidance structure is introduced between the display modules to enable positioning along the first direction without direct mechanical contact that would cause indentation. This intermediary system allows smooth movement while protecting the display surface quality.
3Adaptability or versatility
If a complex sliding mechanism with multiple rollers is used, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The display system is segmented into independently controllable first and second display modules. The second module can be positioned along the first direction with standard precision requirements, eliminating the need for high-precision alignment of multiple rollers and bars while maintaining the ability to adjust display area.
Solution Approach 2:
The complex roller and bar alignment requirements are removed by extracting the sliding function and implementing it through a simplified positioning mechanism. This reduces manufacturing precision requirements to standard levels while preserving adaptability for display area change.

AI summary
A display device includes a display module, a plate including a base portion, and a first sidewall and a second sidewall protruding downward from the base portion to face each other, and disposed under the display module, chain units disposed between the first sidewall and the second sidewall to be spaced apart from each other along a first direction, each extending along a second direction crossing the first direction to be coupled to the first sidewall and the second sidewall, and a roller including bumps inserted between the chain units disposed adjacent to each other, and overlapping the base portion. The display module overlapping the base portion, the base portion, the first sidewall, and the second sidewall are bent with respect to the roller.
