20100053996 | LIGHT GUIDE WITH REFLECTANCE ENHANCEMENT AND LIGHTING SYSTEM INCLUDING THE SAME - According to an aspect of the invention, a light guide is provided which includes a light guide substrate having a top surface through which light is to be emitted, a bottom surface, an incident edge surface through which incident light is to be introduced into the light guide substrate, and another edge surface. The another edge surface includes at least one micro structure operative to reflect at least a portion of the incident light, which travels through the light guide substrate and is incident on the another edge surface, back within the light guide substrate. | 03-04-2010 |
20100066854 | Camera and imaging system - A camera comprises an imaging system having a first depth of field for one or more first colours and a second depth of field, smaller than the first depth of field, for one or more second colours. The imaging system may comprise an iris with a first aperture for the first colour or colours and a second aperture, which is larger than the first, for the second colour or colours. The first aperture may be defined by an outer opaque ring ( | 03-18-2010 |
20100110340 | DISPLAY - A display comprises: a transmissive pixellated spatial light modulator ( | 05-06-2010 |
20100309204 | DISPLAY - A display comprises a parallax optic ( | 12-09-2010 |
20110018860 | DISPLAY - A display is provided having private and public viewing modes. The display comprises a display device and a parallax optic ( | 01-27-2011 |
20110051460 | BACKLIGHT - A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A light guide receives the light from an edge surface and guides the light by total internal reflection. The light extracted from the lightguide has an angular emission profile such that when incident on a prism film, collimated light is produced. | 03-03-2011 |
20110123184 | CAMERA FLASH, A CAMERA, AND A METHOD OF GENERATING A FLASH - A camera flash comprises a light guide arranged to extract light at least through one surface; and one or more light sources arranged, in use, to emit light into the lightguide. Each light source is an LED or a laser diode. The camera flash is connectable, in use, to drive circuitry, the drive circuitry being for driving the light source(s) to emit a pulse of light. The waveguide spreads out the light from the light source(s), so that a flash of light from the camera flash does not present a safety risk, while minimising loss of the light from the light source(s). The camera flash can thus provide a high overall optical output, spread over an extended area (as defined by the waveguide). The lightguide may for example be disposed around a camera module of a mobile telephone camera. | 05-26-2011 |
20110234605 | DISPLAY HAVING SPLIT SUB-PIXELS FOR MULTIPLE IMAGE DISPLAY FUNCTIONS - A display which includes a plurality of sub-pixels each split into a plurality of sub-regions. Each sub-pixel includes a single gate line and a single signal line, and each sub-region within a given sub-pixel includes a corresponding storage capacitor line. An optical element cooperatively combines with the plurality of sub-pixels to create distinct angularly dependent brightness functions in association with corresponding sub-regions within the sub-pixels. Control electronics are configured to provide image data levels in the form of signal data voltages to each sub-region included within each sub-pixel via the gate line and signal line included within the sub-pixel; and to independently modify the signal data voltages provided to each sub-region within the sub-pixels via the corresponding storage capacitor lines whereby the display operates in accordance with at least two different image functions. | 09-29-2011 |
20120176378 | MULTIPLE VIEW DISPLAY - A multiple view display comprises a display device and a plurality of converging lenses, such as a lenticular screen. Each lens cooperates with a respective region of the display device comprising one or more pixels (L) for displaying part of a first image for viewing in a first viewing region (Region | 07-12-2012 |
20120188238 | MULTIPLE-VIEW DIRECTIONAL DISPLAY - A multiple view directional display comprises a pixelated image display layer having a plurality of first pixels assigned to display a first image and a plurality of second pixels assigned to display a second image, and a parallax barrier aperture array for directing light from the first pixels generally into a first viewing window and for directing light from the second pixels generally into a second viewing window not overlapping the first viewing window. The display further comprises first light directing means for re-directing light emitted from a first lateral edge region of each first pixel away from the second viewing window. | 07-26-2012 |
20120242857 | CAMERA INCLUDING IMAGING SYSTEM HAVING DIFFERENT DEPTHS OF FIELD FOR DIFFERENT FREQUENCIES OF OPTICAL RADIATION - A camera including an imaging system having a first depth of field for one or more first frequencies of optical radiation and a second depth of field, smaller than the first depth of field, for one or more second frequencies of optical radiation. The imaging system includes an iris having a first aperture for the first frequency(ies) of optical radiation and a second aperture, larger than the first aperture, for the second frequency(ies) of optical radiation. The first aperture is defined by an outer opaque ring and the second aperture is defined by an inner chromatic ring. The inner chromatic ring blocks the first frequency(ies) and passes the second frequency(ies) such that the image formed by the first frequency(ies) is sharper than the image formed by the second frequency(ies), and that sharpness may be transposed to other images by known image processing techniques. | 09-27-2012 |
