Variable Stiffness Displays: Adaptive Design with ER and MR Fluids
Here’s PatSnap Eureka !
Summary
Problems
Existing flexible displays lack the ability to dynamically adjust stiffness, limiting their versatility and adaptability to various shapes and forms without compromising functionality.
Innovation solutions
A variable stiffness flexible display incorporating an electro-rheological (ER) or magneto-rheological (MR) fluid layer, which changes viscosity and stiffness in response to electrical or magnetic fields, allowing the display to be customized into different shapes and forms, including flexible, semi-rigid, and rigid states.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a flexible display uses a fixed stiffness substrate, then the structural integrity is maintained, but the adaptability to different shapes and forms is limited
Why choose this principle:
The patent applies dynamics by implementing a variable stiffness layer that can dynamically change its mechanical properties between flexible and rigid states. This layer includes electro-rheological or magneto-rheological fluid enclosed between electrodes, allowing the display to adapt its stiffness according to applied electrical or magnetic fields, thus resolving the contradiction between adaptability and structural integrity
Principle concept:
If a flexible display uses a fixed stiffness substrate, then the structural integrity is maintained, but the adaptability to different shapes and forms is limited
Why choose this principle:
The patent changes the physical parameter of stiffness by incorporating a variable stiffness layer with electro-rheological or magneto-rheological fluid. By applying electrical or magnetic fields, the fluid's viscosity and stiffness parameters can be adjusted continuously, enabling the display to transition between flexible and rigid states while maintaining structural integrity when needed

Abstract
A variable stiffness film, a variable stiffness flexible display, and a manufacturing method thereof may include a lower electrode, a variable fluid, and an upper electrode. A polymer layer may be formed on the lower electrode, and a variable fluid receiving portion is patterned on the polymer layer. A variable stiffness layer is formed by putting a variable fluid in the variable fluid receiving portion. The upper electrode is formed on the variable fluid layer.
