TWISTING BALL PANEL DISPLAY ABSTRACT OF THE DISCLOSURE A display system in which the display panel is comprised of a plurality of particles which have an electrical anisotropy due to hemispherical surface coatings of different Zeta potential and their distribution in a volume of a dielectric liquid, and which also have an optical anisotropy due to the hemispherical surface coatings having different optical characteristics which may be due to the color or other optical properties of the hemispherical coatings. Under the action of an external electric field, the particles will rotate in accordance with their electrical anisotropy to provide a display in accordance with their optical anisotropy. The display has switching threshold and memory capabilities.
