  • Publication number: 20190037185
    Abstract: A light projection system for generating an image with three primary colors, each primary color being respectively defined by a first, second and third wavebands. The system includes a first blue laser source emitting a first beam in a fourth waveband, the first blue laser source having a first laser driver, a second blue laser source emitting a second beam having a central wavelength and a fifth waveband, the second blue laser source having a second laser driver, a substrate having a wavelength conversion element for emitting light at a plurality of wavelengths after absorption of a light beam at an excitation wavelength within a fifth waveband of the second blue laser source and a beam combiner for combining the combined first beam and the converted beam, which combination results in a white beam. Dichroic losses can be reduced by using a green phosphor together with red laser assistance.

  • Patent number: 9986214
    Abstract: An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light for controlled periods of time. Adjacent screens can be configured to selectively reflect light during different periods of time. The projector systems can be configured to project video onto their respective screens while the associated screen is configured to selectively reflect light rather than absorb light.

  • Patent number: 8665518
    Abstract: A display method and system are described for displaying a stereo image comprising a first image and a second image. A light valve array comprising an array of light valve elements is driven according to an image and a light source is provided for generating a shaped light beam which can illuminate a portion of the light valve array. A scanning device is provided which is arranged to scan the shaped light beam across the light valve array. Light valve elements of the same light valve array are caused to sequentially adopt a state representative of the first image of the stereoscopic image and a state representative of the second image, and to cause the light valve elements to adopt a new state representative of one of the first and second images in advance of the scanning by the shaped light beam and to change to a new state representative of the other of the first and second images during a period between successive scans of the shaped light beam.

  • Patent number: 7832869
    Abstract: In one aspect, the present invention relates to a stereoscopic projection system including a projection device with at least one filter which filters a parameter of the light in a color selective manner. The at least one filter which filters a parameter of the light in a color selective manner has a spectral characteristic for transmitting light in a first wavelength band or set of wavelength bands and for reflecting light in a second wavelength band or set of wavelength bands. The projection device includes a device, such as e.g. a rotating wheel or a sliding filter, for fast synchronized switching between light in different wavelength bands or sets of wavelength bands.

  • Patent number: 7692866
    Abstract: A color display (100, 200) for displaying an image is described wherein the color display (100, 200) is adapted for displaying a number of basic color light channels (102a, 102b, 102c). The color display (100, 200) comprises a basic color combiner (112, 212) for combining the basic colors and at least one basic color light channel (102a, 102b, 102c) comprising at least two light sources (104) having different spectral characteristics. The color display (100, 200) furthermore comprises an adjuster (106, 206) for adjusting a basic color by adjusting a relative proportion of a luminous output from the at least two light sources (104) in the basic color light channel (102a, 102b, 102c). A corresponding adjuster/controller, a multi-display system and a corresponding method for setting and/or adjusting a display system also is described.

  • Publication number: 20100007592
    Abstract: The invention relates to controlling the brightness control signal for a pixel of a liquid crystal display. According to the invention, a method of controlling the brightness control signal for a first pixel of a liquid crystal display for displaying a predetermined image is provided, comprising the following steps: determining the intended brightness of the first pixel according to the predetermined image, determining the brightness of a second pixel, and calculating the brightness control signal for the first pixel on the basis of a function of the intended brightness of the first pixel and the brightness of the second pixel, wherein the function is a predetermined correction function according to which the influence of the brightness of the second pixel on the brightness of the first pixel due to fringe field effects between the first pixel and the second pixel is corrected. This method provides for the advantage that a more realistic image can be displayed.

  • Patent number: 7618147
    Abstract: A display system (100, 200, 300, 350, 400, 450) for displaying an image is described. The display system (100, 200, 300, 350, 400, 450) typically comprises one or a plurality of individual light sources (102) and a light collecting stage (110, 210, 310, 410) which comprises a separate light collecting sub-system associated with each light source (102), or group of light sources (102). The display system (100, 200, 300, 350, 400, 450) typically comprises at least one light modulator (120) which is operable to modulate light received from the light collecting stage (110, 210, 310, 410) according to an image which is to be displayed. Finally a projection stage (130) is provided for projecting the image, typically on a projection screen. The present invention also relates to a corresponding method. The present invention is especially useful with light sources having a packaging around the light emitting surface such that the light sources cannot be physically placed adjacent to each other.

  • Patent number: 7495830
    Abstract: A polariser or a system for lighting using such a polariser in a polarisation recuperation system. The polariser comprises first and second polarising beam splitters (212a, 212b) for splitting first and second unpolarised beams each into at least first and second polarised beams of different polarisation states. The first and second polarised beams are guided to first and second light paths respectively. On these light paths controllable polarisation conversion elements (218a, 218b) are arranged such that the second polarised beam from the first unpolarised beam time-shares a same path through the polarisation conversion element (218a, 218b) as the first polarised beam from the second unpolarised beam. The controllable polarisation conversion elements are switchable to alternately convert and not convert the polarisation state, depending on which beam is switched to pass through the polarisation conversion elements (218a, 218b), corresponding with which of the first or second unpolarised beams are present.
