MAGNETIC FLUID DISPLAY DEVICE |
摘要 |
An immiscible, transparent fluid and an opaque magnetic fluid are contained within a defined volume, such as a sandwich-type construction having a transparent face through which an optical display may be observed. The transparent fluid preferentially wets the wall and results in complete displacement of opaque fluid when the fluids are moved one to the other. A magnetic field captures the magnetic fluid in a predetermined optical pattern. The optical pattern is controlled by varying the intensity and location of the magnetic field to produce various patterns.
