Abstract
A flat-panel display comprises a gelatinous material between two panels having a matrix of pixel electrodes formed between the panels. Suspended ionic particles in the gelatinous material, of a color contrasting to the color of the gelatinous material, are translated in the gelatinous material by activating individual ones of the electrodes, and collecting near the electrodes against one of the panels, form pixels of the color of the particles against a background of the color of the gelatinous material. In preferred embodiments data receiving and control circuitry are provided with the flat panel display for activating electrodes in patterns according to received data, the patterns forming images on a screen. Flat panel displays thus formed require power only when an image on the screen is changed. No power is required to maintain an image once formed. Such a display is especially suitable for forming pages of text for various purposes.
