Patent number: 7035017Abstract: A projection lens system which includes a telecentric lens assembly. The lens may be used to form an image from a light source, including for example a resonant microcavity phosphororcathode ray tube, onto a screen or display, such as in a television or a projection device. In accordance with one embodiment, a planar cooling gap or cavity (which may or may not contain a cooling liquid) is included between the imaging surface and the matching planar surface of the field lens. The use of a planar gap alleviates any temperature differentials across the cooling liquid and the lens surfaces, as compared with alternate designs that may have a non-planar gap between the faceplate and the field lens, or that use liquid lenses.Type: GrantFiled: April 16, 2004Date of Patent: April 25, 2006Assignee: Quantum Vision, Inc.Inventors: Biljana Tadic-Galeb, Robert E. Fischer, Larry D. Owen

Patent number: 7009211Abstract: A resonant microcavity display comprises a thin-film resonant microcavity (20, 50, 60) with an active layer (21). The microcavity (20, 50, 60) comprises a front reflector (22, 52), the active region (21) deposited upon the front reflector, and a back reflector (20, 54) deposited upon the active region (21). The display preferentially emits light that propagates along the axis (27) perpendicular to the plane of the display, due to its quantum mechanical properties. The extrinsic efficiency of this device is increased by the use of thin film construction with anomalous phase dispersion.Type: GrantFiled: March 18, 2003Date of Patent: March 7, 2006Assignee: Quantum Vision, Inc.Inventors: Hergen Eilers, Steven M. Jaffe, Brian L. Olmsted, Michieal L. Jones
