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.

Abstract: The present disclosure provides discussion of screen vibration to reduce speckle in display applications and/or projection screens. Electrical transducers or reactors may be used with a screen to reduce or remove speckle in projection screens and/or display applications. Electrical transducers may not be directly mounted to a screen, thus eliminating many mechanical failure modes associated with a vibrating transducer as well as resulting in a much quieter operation. By design, the reactors or transducers may actually contact the screen, and can take up less than one square inch of screen surface each, than previous designs, which may be outside of the active viewing area and within 12 inches of the screen border, preferably less than approximately 1 inch from screen edge. The reactors are magnets, though any ferrous material can be made to work with certain operating conditions.

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. These functions may include an intensity envelope in addition to substantially complying with the Digital Cinema Initiative (“DCI”) security concerns.

Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

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.

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.
