摘要： Disclosed herein is an optical device having a light source, a viscoelastic lightguide and a retroreflective film suitable for retroreflecting light. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The transported light is extracted from the lightguide and retroreflected at a structured surface of the retroreflective film The optical device may have a “front lit” or a “back lit” configuration depending on the relative positioning of the lightguide and the retroreflective film The retroreflective film may include prismatic retroreflective sheeting, holographic film or film structured with diffraction gratings. The optical device may be used, for example, as a sign or marking, a license plate assembly, a tail light assembly for vehicles, a security laminate for protection of documents against tampering, or an illumination device.

摘要： A backlight includes n1, n2, and n3 colored LED light sources of a first, second, and third (non-white) color respectively, and a drive circuit connected to these sources. The drive circuit is configured to drive each of the first, second, and third light sources within a specified percentage, such as 10%, of their respective maximum drive characteristics, and the numbers n1, n2, and n3 are selected so that light from the energized first, second, and third LED light sources, when combined, is substantially white. In some cases, the backlight also includes a number n4 of white LED sources, and the colored LED sources may or may not be driven within 10% of their maximum ratings. The number n4 of white sources is selected to increase the brightness of the backlight while maintaining the color gamut of the backlight output within a specified percentage, such as 10%, of a desired specification.

摘要： A reflector laminate, and backlights and displays incorporating such reflector laminates are disclosed. The reflector laminate includes a substrate and a reflector that are adhered together by a plurality of adhesive protrusions. The adhesive protrusions provide for a plurality of voids between the reflector and the substrate, so that a free reflector surface is adjacent to an air gap between the reflector and substrate. The reflector can include a multilayer interference reflector, and the presence of the air gap ensures high reflectivity for the laminate. The reflector can be adhered to a solid lightguide, a frame enclosing a portion of a backlight, a frame enclosing a hollow lightguide cavity, or an optical sheet positioned at the output surface of a backlight.
