20080316375 | ZScreen® modulator with wire grid polarizer for stereoscopic projection - A projection design configured for use with a projector having a projector lens is provided. The device includes at least one pi-cell or pi-cell electro-optical modulator in combination with a wire grid polarizer mounted proximate the pi-cell(s). The design may include a cleanup polarizer between the pi-cell(s) and the wire grid polarizer and optionally a protective window between the wire grid projector and projection lens. The device may be oriented at an angle substantially differing from the axis of the projector lens. The resultant device includes spacing for airflow and can offer improved performance, particularly in heating, over designs previously available. | 12-25-2008 |
20090051832 | Portable image projection device - The present invention relates to an image projection device of the type playing images receive via remote means or read from a stored data media. When a mobile phone, the device includes an image projection capability in addition to the standard display. Both the display and the image may be the same or may differ according to the user requirements. The device may also be a smart card or compact disc player that projects an image of the data. The device may further still include a camera to record an image and in the case of a mobile phone transmit it to another receiver. This allows the use of mobile phones for video conferencing. | 02-26-2009 |
20110032437 | VIDEO IMAGE EVALUATION EQUIPMENT - A video image evaluation equipment of the present invention is capable of converting circularly-polarized light emitted from a circularly polarizing light source into linearly-polarized light so as to transmit an absorption-type linear polarizer by a wavelength plate to be incident on a liquid crystal panel. This makes it possible to enter and reflect light emitted from the circularly polarizing light source on the liquid crystal panel without loss, which leads to display brighter video images than conventional ones. | 02-10-2011 |
20110194038 | PROJECTION-TYPE DISPLAY APPARATUS - A projection-type display apparatus, being suitable to be applied as a light source of a solid-state light source, in the place of a conventional lamp, comprises: a light source unit, which is configured to emit a white-color light therefrom; a light separation optic system, which is configured to separate the white color light from the light source unit into three primary color lights, R (red-color), G (green-color) and B (blue-color); R, G and B light modulating portions, each of which modulates each of R, G and B polarized lights separated, depending on a video signal, respectively; a light composing unit, which is configured to compose optical images, which are formed by the R, G and B light modulating portions; and a projecting portion, which is configure to project the optical image composed, enlargedly, wherein the light source unit emits a white color light emitting from a nearly point-like light source, including an excitation light from a solid-state light emitting element therein. | 08-11-2011 |
20120182487 | Laser Projection Apparatus - Provided is a laser projection apparatus which forms each one frame by performing two-dimensional scanning with laser light and projects images on a screen ( | 07-19-2012 |
20130063670 | ACTIVE SHUTTER GLASSES AND A STEREOSCOPIC IMAGE PROJECTION SYSTEM - The present invention provides active shutter glasses and a stereoscopic image projection system that allow a stereoscopic image of excellent display quality to be viewed. The present invention provides active shutter glasses for a stereoscopic image projection system in which the active shutter glasses include a shutter section for the right eye and a shutter section for the left eye, the shutter section for the right eye and the shutter section for the left eye each include a liquid crystal cell, and when the glasses are worn, viewing angles of the shutter section for the right eye and the shutter section for the left eye each are wider on the right and left sides than on the upper and lower sides. | 03-14-2013 |
20140092321 | PROJECTION TYPE IMAGE DISPLAY DEVICE - To effectively suppress speckle noise generated when coherent light is used as a light source in a projection type image display device using an LCOS (Liquid Crystal On Silicon). | 04-03-2014 |
20140132851 | MINIMIZED-THICKNESS ANGULAR SCANNER OF ELECTROMAGNETIC RADIATION - A minimized-thickness angular scanner of electromagnetic radiation includes an optical sandwich having a two-dimensional (2D) image source, and a scanning assembly that includes a first optic and a second optic, wherein at least one of the first optic and the second optic are oscillatorily translating. Translation of the optics provides for generation of a three-dimensional (3D) image, while the optical sandwich design provides for compact implementation of 3D displays. | 05-15-2014 |
20160048030 | LIGHT-FIELD IMMERSIVE DISPLAY AND OPERATION METHOD THEREOF - A light-field immersive display includes a curved screen, at least two projectors, and at least two curved liquid crystal slits. Each of the projectors has a projected image on the curved screen. Boundaries of the two projected images are edge-blended. The curved liquid crystal slits are disposed on one side of the curved screen, and the curved liquid crystal slits are respectively disposed corresponding to the projected images. | 02-18-2016 |
