Publication number: 20100259488Abstract: Embodiments are disclosed herein related to the avoidance of undesirable optical effects in a liquid crystal display used with a touch-sensitive display input device. For example, one embodiment provides a user interface comprising a body, a light source disposed within the body, and a liquid crystal display configured to create an image displayable on one or more display surfaces coupled to the body. The user interface device further includes a light delivery system positioned optically between the light source and the liquid crystal display to deliver light produced by the light source to the liquid crystal display. The light delivery system comprises a light exit surface spaced from the liquid crystal display to form a gap positioned between the light exit surface of the light delivery system and the liquid crystal display.Type: ApplicationFiled: April 13, 2009Publication date: October 14, 2010Applicant: Microsoft CorporationInventors: Glen C.

Publication number: 20100091254Abstract: A light guide of the tapered-waveguide type includes an input slab (30) for expanding a projected image between an input end and an output end (40); and a tapered output slab (10) arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide (30) is greater in the transverse direction away from the centre line C, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide (10) bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.Type: ApplicationFiled: October 2, 2007Publication date: April 15, 2010Applicant: Microsoft CorporationInventors: Adrian Travis, Timothy Andrew Large, Neil Emerton

Publication number: 20100053771Abstract: A flat panel lens system as a tapered light guide that has minimal or no margin for fan out. The tapered light guide includes a thin end, and a thick end of which is a bevelled mirror or an optical equivalent. Light is injected into the thin end and the mirror is such that rays injected through a point at the thin end emerge collimated from one of the light guide surfaces, and that collimated rays injected at an appropriate angle through one of the light guide surfaces emerge from a point at the thin end. Bragg gratings can be utilized for color implementations as well. The tapered light guide can be fabricated as a single piece, by extrusion, injection molding, or the combination/variation of extrusion and injection molding, as well as other commonly known techniques.Type: ApplicationFiled: September 3, 2008Publication date: March 4, 2010Applicant: Microsoft CorporationInventors: Adrian Travis, Timothy A. Large, Neil Emerton

Patent number: 6019455Abstract: A method of depositing material on a surface (136) is described in which a bulk medium (for example ink 122) in the form of a composition of dispersed insoluble material (for example ink particles) and a support medium is supplied to a cell (120). A movement of the insoluble material within the bulk medium is effected towards a transfer aperture (128) within the cell, thereby concentrating the insoluble material within the bulk medium. Thereafter the insoluble material is removed from the concentration within the bulk medium through the aperture (128) and deposited onto the surface (136).Type: GrantFiled: November 22, 1996Date of Patent: February 1, 2000Assignee: Tonejet Corporation Pty.
