Abstract: A linear array of liquid crystal shutters (12) mounted near a photoreceptor surface (14) and arranged transversely to the direction of travel of the photoreceptor surface; an array of thin film transistors (122) connected to the array of liquid crystal shutters for electrically driving the shutters, and logic means (66) connected to the array of thin film transistors selectively pulsing the liquid crystal shutters to expose the photoreceptor surface selectively a line at a time. The system further includes means for producing an electric field between the opposed electrodes of each of the liquid crystal shutters to prevent passage of light through the shutters, and means for selectively de-energizing each of the pairs of electrodes for a predetermined period in response to the receipt of input data signals.

Abstract: There is disclosed an imaging system for forming a plurality of images on the same surface. The imaging system includes an electro-optic imaging member comprising a voltage or current-sensitive light modulating layer, a layer of photoconductive material which exhibits persistent photoconduction properties and a layer of material capable of generating photoinjection currents when struck by radiation which it absorbs.

Abstract: A display for use in conjunction with a copier. The disclosed display comprises two microprocessors for controllably displaying information on a display panel of a xerographic copier. A first microprocessor is primarly responsible for energizing alphanumeric elements to either send messages to the copier user or to prompt the user to interact with the copier. A second display is a liquid crystal display wherein selectively energizable liquid crystal elements corresponding to copier components can be rendered visible under the control of the second microprocessor. An overlay pattern can be placed above the liquid crystal display to present to the user in outline form the copier architecture with which he is interacting. This overlay can be changed as the copier configuration is changed. The electronics for controlling the display of alphanumeric allows the utilization of different fonts and/or different languages. This flexibility allows the copier to prompt, and/or display information regarding copier status in various languages without a redesign of the display unit.
