    摘要： Magnetic display devices include low-density silica coated magnetic and nonmagnetic particles. In a one-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with non-magnetic particles. In a two-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with low-density silica coated non-magnetic particles. Display devices employing silica coated magnetic particles minimize the tendency of the magnetic particles to aggregate. Silica coated magnetic particles in a display device results in a magnetic display with improved image stability. Low-density silica coated magnetic particles in a display device allow for particles to move easily through a dispersion fluid in response to a magnetic field.

    摘要： A cholesteric display including a cholesteric liquid crystal, and a dipolar dopant having limited miscibility in the cholesteric liquid crystal is provided. In accordance with another aspect, a process is provided for forming a cholesteric liquid crystal composition by dissolving a dipolar dopant having limited solubility into a cholesteric liquid crystal. The liquid crystal composition can be utilized to produce a cholesteric display. The liquid crystal domains in the liquid crystal composition rotate away from a planar state in the presence of an applied electric field and the degree of rotation is a function of the applied electric field strength. The reflected color is then a function of the applied electric field.
