Abstract: An optical tapered waveguide for use in optical arrays is described which contains at least one inclusive structure. The inclusion may possess an abrupt refractive index interface within the body of the tapered optical waveguide or it may consist of a graded refractive index region within the tapered optical waveguide. The tapered waveguide propagates light rays via total internal reflection from the sidewalls of a tapered optical waveguide. The different refractive index of the inclusion also acts to alter the direction of the light rays passing through the waveguide. The tapered waveguide is advantageously useful in an array of waveguides for use in display devices, such as for example projection display devices, off screen display devices, and direct view displays. Such displays are used in a wide range of applications including computer terminals, airplane cockpit displays, automotive instrument panels, televisions, and other devices that provide text, grapics, or video information.

Abstract: An improved backlighting apparatus comprising a slab waveguide (6) that accepts light rays generated by a light source (4) and transmits the light rays via total internal reflection. Attached on one face of the slab waveguide is an array of microprisms (28), with each microprism (28) having a light input surface (30) parallel to a light output surface (32) and at least one sidewall (33) tilted at an angle from the direction normal to the surface of the waveguide (6) such that light rays escape from the slab waveguide (6), reflect off the tilted sidewall (33) and emerge from the microprism (28) as a light source substantially perpendicular to the light output surface (32). An array of microlenses may be positioned to accept the output of the microprisms so that the light exiting from the microlenses is substantially more perpendicular. The backlight apparatus is advantageously used as a backlighting means for flat panel electronic displays.

Abstract: An improved backlight assembly (2) comprising an array of apertures (8) in close proximity to a light source (6), an array of tapered optical elements (10) that have a light input surface area smaller than the light output surface area. Light rays pass through the apertures and are directed to the optical elements which transmit the light rays via internal reflection to provide a partially collimated light source. The light rays then pass through an array of microlenses (12) that transmit the light rays via refraction and provide a substantially more collimated light source for the display elements of a display (16). The backlight assembly is advantageously used as a backlighting means for electro-optical displays, especially those designed for military and avionics applications.

Abstract: The present invention is directed to a process for making an array of tapered photopolymerized waveguides. The tapered waveguides are useful as a display means in direct view devices and projection display devices. In step (a), a photomask is placed in substantial contact with a substrate wherein the photomask has opaque and transparent regions. In step (b), a substantially uniform thickness of photopolymerizable mixture is placed on the substrate so that the substrate is positioned between the photopolymerizable mixture and the photomask wherein (i) the photopolymerizable mixture comprises at least one reactive monomer and photoinitiator and (ii) the photoinitiator is present in an amount sufficent to form a gradient of substantially collimated actinic radiation across the thickness of the photopolymerizable mixture during subsequent step (c). In step (c), while maintaining the photopolymerizable mixture and substrate in a substantially fixed plane relative to the substantially collimated actinic radiation, the photopolymerisable mixture is exposed through the transparent regions of the photomask to the substantially collimated actinic radiation for a time sufficent to form an array of tapered photopolymerized waveguides wherein (i) the tapered end of each of the waveguides extends outward from the substrate, (ii) each of the waveguides has a light input surface adjacent the substrate and a light output surface distal from the light input surface, and (iii) the area of the light input surface of each of the waveguides is greater than the area of its light output surface. In step (d), the photomask and photopolymerizable mixture which was not substantially polymerized by the substantially collimated actinic radiation during step (c) are removed from the substrate.
