Abstract

A liquid crystal display is shown, in which the magnetic field of bubble domains is used to switch the state of the liquid crystal material. The magnetic field of the bubbles switches the liquid crystal from a turbid state to a clear state in localized regions where the bubbles are located.

Bubble Domain Driven Liquid Crystal Display

A liquid crystal display is shown, in which the magnetic field of bubble domains is used to switch the state of the liquid crystal material. The magnetic field of the bubbles switches the liquid crystal from a turbid state to a clear state in localized regions where the bubbles are located.

A propagation structure, such as permalloy, can be provided to move the magnetic bubble domains in a material, such as an amorphous bubble domain material. Thus, information can be coded into the propagation circuits for moving the bubble domains, where the information is then directly viewable as represented by the localized liquid crystal state.
