Abstract: A laminar electroluminescent EL display formed of aligned side-by-side light line segments adaptable to providing a raster-like screen for information such as liquid crystal information generated in overlying relationship with the display area. The electrically energized line segments of light emitting matter can be deposited in aligned grooves in a common electrode and individual opposite electrodes for each of the line segments are aligned in an overlying carrier matched to the lines of light emitting matter.

Abstract: An electroluminescent laminate assembly or panel adaptable to formation of images of light generated by light emitting matter. The luminescent laminate is arranged with light emitting sections shaped in the form of images desired. In addition, different gradations in light intensities can be imparted to different segments of the field of the desired image for apparent three dimensional effects by selective provision of thick and thin regions of the light emitting matter between the electrodes. The electrodes are also disclosed as capable of formation from compositions of conductive material which in some instances can be sprayed in place and in others doctor-bladed in place to different thicknesses for application of different electrical forces to different sections of the light emitting matter of the assembly for desired preselected patterned light outputs.

Abstract: An energy saving electroluminescent sheet or panel adaptable to lighting of writing or drawing sheets to permit writing thereon in the dark or to lighting sheets to permit reading of written or other intelligible matter thereon. The luminescent sheet or panel has a light field composed of a number of electrically activatable light segments adaptable to activation independently or in sequence at an intermittent rate or frequency sufficient that the normal eye persistence of observers will produce in effect a coherent light output from the entire light field or selected portions of the light field with a relatively small power source. The light segments can be aligned in any of a number of relationships such, for example, as in side-by-side relation, in radially extending relation or in circumferentially relation.

Abstract: An electroluminescent panel assembly for use in darkness or dim light in which side-by-side light strips form an integrated light field with non-lighted regions between which function as dark guidelines to guide writing on overlying sheets of material through which the integrated luminescent field is visible upon energization of the light strips.

Abstract: An electroluminescent glow sheet having multiple layers containing electrically activatable light emitting matter for emission of light from opposing surfaces, the different layers being adaptable to giving off light of different colors and being adaptable to use in contained condition or when withdrawn from the container.

Abstract: A portable containerized electroluminescent glow sheet withdrawably contained in a cartridge formed of a flexible electroluminescent sheet spirally wound and contained in a cylindrical cartridge, the luminescent sheet having its own power source contained in the cartridge to permit convenient carriage and use for lighting purposes such as reading and writing in the dark.

Abstract: A lined phosphorescent backing sheet for use in underlying relation with writing paper or drawing sheets permitting a writer to write in orderly form in the dark without need for external light.

Abstract: An energy saving electroluminescent backing sheet or panel for back lighting of writing sheets, drawing sheets or sheets having reading or other intelligible matter thereon the backing sheet having a unitarily associated light-weight light activating source capable of providing a low level nondistracting light output which permits its portable use for reading and writing in the dark without need for external light.

Abstract: A phosphorescent backing sheet for use in underlying relation with light transmitting writing sheets, drawing sheets or sheets having reading or other intelligible matter thereon in lines thick enough to permit a person to read in the dark as well as write in the dark.
