Stretchable Display Panel Layout for Alternating Unit Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The service life of stretchable display devices is often short due to uneven wear and tear between different display units, leading to reduced display consistency and overall panel lifespan.
Innovation Solution
A stretchable display panel with a substrate containing hollows, where display units are strategically positioned to alternate their active and inactive states based on the panel's contraction states, ensuring that only necessary units perform display functions in contracted states, thereby balancing the usage and extending the lifespan.

If all display units are always disposed on the light-exiting surface to maintain display functionality, then display coverage is improved, but uneven wear and short service life occur
Solution Approach 1:
The display units are made dynamically reconfigurable between two positions: light-exiting surface (for display) and opposite surface (for rest). The stretchable substrate enables this dynamic repositioning through its elastic properties, allowing units to alternate between active and inactive states to balance wear across all units.
Solution Approach 2:
Display units operate in periodic cycles, alternating between displaying on the light-exiting surface and resting on the opposite surface. This periodic switching ensures that not all units wear out simultaneously, extending the overall service life of the display panel while maintaining continuous display capability.
2Reliability
If display units are fixed on the light-exiting surface to ensure consistent display quality, then display consistency is improved, but premature wear reduces overall lifespan
Solution Approach 1:
The system dynamically switches which units are active on the light-exiting surface versus resting on the opposite surface. This dynamic allocation maintains display consistency during active periods while distributing cumulative wear across all units over time, thereby extending the panel's operational lifespan.
Solution Approach 2:
Individual display units are temporarily 'discarded' from the light-exiting surface to the opposite surface when not needed for display, allowing them to rest and recover. This rotation ensures that while some units are always active (maintaining consistency), others are recovering (extending lifespan).

AI summary
A stretchable display panel, a control method of the stretchable display panel, and a display device are provided. The stretchable display panel includes a stretchable substrate and a plurality of display units. The stretchable substrate contains a plurality of hollows, and a display unit is disposed corresponding to a hollow. The plurality of display units include a first display unit and a second display unit. In a stretched state, both the first display unit and the second display unit are disposed on a side of the stretchable substrate facing a light-exiting surface. In a first contracted state or a second contracted state, one of the first display unit and the second display unit is disposed on the side of the stretchable substrate facing the light-exiting surface, and the other one is disposed on a side of the stretchable substrate away from the light-exiting surface.
