  • Publication number: 20150177530
    Abstract: Generally, near seamless electronics displays may be employed in cinema and exhibition applications. Laser scanned displays may be enabled such that the display may display three dimensional (ā€œ3Dā€) content. A first method to enable a laser scanned display for 3D content may employ polarization, with or without polarization conversion and another method may employ multiple colors. Additionally, the envelope function that may be employed across the display may be achieved by changing laser power as a beam is scanned on the screen or by changing the dwell time of the laser beam on the pixels. One method of minimizing the effects of seams in the screen may be to reduce the screen resolution near the seams by screen design and/or laser beam dwell time or illumination energy.

  • Publication number: 20150153995
    Abstract: Disclosed is a method and apparatus for substantially eliminating the appearance of seams between tiled panels of a display. Non-imaging magnification may be used to substantially eliminate the appearance of seams. Additionally, the appearance of seams between the tiled panels of a display may be substantially eliminated by employing propagation based elimination. The methods disclosed can be used to generate substantially seamless 2D and 3D displays. Additionally, a method and apparatus for achieving substantially uniform panel brightness and color correction may be addressed. The substantially seamless tiled displays may employ specific data formats for use in displaying images on the individual displays which may be tiled together to form a larger, substantially seamless tiled display and may employ other techniques not utilized in known video wall applications.

  • Patent number: 8995061
    Abstract: Disclosed herein are techniques for the reduction speckle of a projection display system using novel lenslet integrators and related methods. In one embodiment, a lenslet integrator system for reducing speckle on a display screen may comprise a first lenslet array configured to receive incoming light for use in displaying an image on a display screen. Specifically, the first lenslet array has motion sufficient to reduce speckle by averaging multiple speckle patterns across its array. Such an exemplary system may also include a second lenslet array configured to receive light that is roughly focused from the moving first lenslet array, due to the motion of the first array. In addition, such systems may also include an output lens configured to receive light focused from the second lenslet array for output from the system for illumination of the display screen.

  • Publication number: 20140362437
    Abstract: The present disclosure includes systems and methods for solving speckle problems by exciting the screen with a more complex vibration spectrum. A range of frequencies provides, in effect, a collection of overlapping patterns of high and low displacement, so that all regions of the screen have enough motion to reduce visible speckle. As previously discussed acceptable speckle may be approximately 15% contrast or less, preferably approximately 5% contrast or less at approximately 15 feet from the screen.

  • Publication number: 20140247484
    Abstract: Disclosed herein are systems and related methods for reducing speckle on display screen. More specifically, screen vibration is used to reduce speckle, and in accordance with the disclosed principles, the vibration may be achieved by using wave-based actuation (e.g., acoustic or electromagnetic waves) to vibrate the screen. In an exemplary embodiment, a speckle reducing system may comprise at least one actuating element located proximate to, but not in physical contact with, a display screen. In addition, the at least one actuating element may be configured to generate waves directed towards the display screen. When the waves impact the display screen, the waves impart vibration to the display screen.

  • Patent number: 8495073
    Abstract: Systems and methods for processing content packages such as human-readable documents identify and analyze content type. Structural and logical evaluation of a Content package is performed, followed by analysis and indexing of concepts within the package. Analysis and identification of concepts and sub-concepts may be an iterative process. Concepts are indexed in accordance with different rule sets representing Different consumer needs and perspectives. Customers can then use the indices to navigate large groups of content packages based on the concepts contained within those packages and also on keywords associated with concepts.

  • Publication number: 20130010265
    Abstract: Illuminating coherent or partially coherent light may be directed over an optical fiber and may be despeckled by vibrating the optical fiber or by increasing the number of modes and modal dispersion. An exemplary embodiment is directed to an optical fiber attached to a vibrating device operable to vibrate the optical fiber above a threshold frequency. Another exemplary embodiment is directed to an optical fiber configured to have a refractive index profile operable to increase the number of modes and modal dispersion.

  • Patent number: 7710845
    Abstract: The light energy necessary for the precure process is held by the RFID at the holographic memory. The controller acquires the light energy corresponding to the temperature of the recording position detected by the temperature sensor out of the precure information acquired by the RFID reader. The exposure time (light emitting time of LED) Te in the precure process is calculated based on the calculating equation Te (sec)=En (joule)/Pd (watt) from the energy En and the intensity Pd of light irradiated onto the recording position detected by the light detector.

  • Patent number: 7679060
    Abstract: An improved nanophosphor scintillator liquid comprises nanophosphor particles in a liquid matrix. The nanophosphor particles are optionally surface modified with an organic ligand. The surface modified nanophosphor particle is essentially surface charge neutral, thereby preventing agglomeration of the nanophosphor particles during dispersion in a liquid scintillator matrix. The improved nanophosphor scintillator liquid may be used in any conventional liquid scintillator application, including in a radiation detector.

  • Patent number: 7551538
    Abstract: To provide an optical recording apparatus capable of effectively suppressing useless fixation to an information-unrecorded area during a fixing process with a simple structure, and an optical head. Upon recording information, a movable lens of an expander lens 104 is positioned in an information recording position. In an information fixing process, the movable lens of the expander lens 104 is positioned in a fixing-process position. In this case, a range of irradiation to the recording medium with the data light becomes somewhat wider than that in the information recording process. Accordingly, it is possible to fix the information to an area irradiated with the data light in the information recording process without fail. In addition, the irradiation range is only somewhat wider than that in the information fixing process, making it possible to minimize the region uselessly subjected to the fixing process.
