In one embodiment of the present invention, a collaboration engine is configured to display shared digital assets consistently across displays. The collaboration engine receives container metadata generated based on a first location and first size of a digital asset within a first scaled workspace displayed on a first display. In response, the collaboration engine computes a second location and second size of the digital asset based on the container metadata and the size of a second scaled workspace. Finally, the collaboration engine configures the second device to display the digital asset within the second scaled workspace based on the second location and the second size. Notably, the container metadata correlates to the appearance of the digital asset on the first display, and the appearance of the digital asset on the second display correlates to the container metadata. Consequently, the appearance of the digital asset is consistent across the displays.

Various embodiments provide confidentiality-based file hosting by automatically directing assets in a shared workspace to appropriate storage locations. The storage location can be determined by comparing a security level that is associated with an asset to security levels of multiple possible storage locations. If a security level of the asset is changed in the shared workspace, the asset is automatically directed to an appropriate storage location based on the changed security level. This can include directing the asset to either a more secure or a less secure storage location.

In one embodiment, the modular display includes aggregates of individual panel tiles arranged between two large plastic sheets. The footprint of the large plastic sheet sandwich becomes the dimension of the display screen. The tilettes are phosphor emission panels with a full complement of emittable pixels. By separating the tilettes from the final full dimension sheet, the tilettes can be manufactured in transportable sizes and the outer full dimension sheets can be rolled for easy transport to the final install location.

Implementations described herein generally relate to scanning beam display systems and more specifically, to systems and methods for improved image alignment of such scanning beam display systems. The method comprises providing a display system comprising a display screen having a plurality of display screen region each with a corresponding light engine module having a servo laser beam and an excitation laser beam, scanning the servo laser beam of a light engine module in an outer scanning region outside of the light engine module's corresponding display screen region, detecting servo laser beam feedback light to measure an alignment error of the light engine module relative to the light engine module's corresponding display screen region, and adjusting alignment of the excitation laser beam based on the measured alignment error.

A scanning beam display system includes an optical module, an image control module, and a display screen on which optical beams are scanned. The optical module includes a vertical adjuster placed in the optical paths of the beams to control and adjust positions of the optical beams along a generally vertical direction on the display screen, and a control unit configured to receive control instructions for the vertical adjuster and to control the vertical adjuster to be at one of a predetermined number of orientations to place the scanning optical beams at a corresponding distinct position on the display screen. The control unit is further configured to apply an adjustment offset to each orientation of the vertical adjuster such that each immediately vertically adjacent pair of beam footprints projected on the display screen resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.

Techniques and optically excited light-emitting devices based on phosphors are provided to use phosphor materials which absorb excitation light to emit visible light and include a composite phosphor material including two or more different transition metal compounds that, under optical excitation of the excitation light, emit visible light at spectrally close but different spectral wavelengths or bands that spectrally overlap to produce a desired color.

A 2-D scanning system uses a fast-rotating raster-polygon as a single scanning component to produce straight scan lines over a 2-D image surface. An approach angle of incident light beams to the raster-polygon is selected to minimize pin-cushion distortion of scan lines introduced by polygon scanning on the image surface, and a tilt angle of the rotational axis of the raster-polygon is selected to position said polygon-scanning distortion symmetrically on the image surface. In addition, scan optics are configured to generate a predetermined amount of barrel distortion of scan lines on the image surface to compensate for pin-cushion distortion introduced by polygon scanning.

摘要:
The display of a portion of an image in successive rows of display tiles in a tiled display system are delayed, so that the top portion of a first display tile is illuminated immediately after the bottom portion of a second display tile is illuminated, where the second display tile is adjacent to and above the first display tile. This removes the appearance of a broken up image when the image moves across the display tiles in a direction somewhat parallel to the direction of raster scanning. In this way, a raster scanning tiled display system does not produce a stair-step effect even though the top and bottom portion of an image on a tile in the tiled display system is raster-scanned at different times.
摘要:
Systems and techniques for scanning-beam display are provided to use local dimming on the optical energy of at least one optical beam to minimize the non-uniform image brightness across the screen. This local dimming during the beam scanning can be achieved by adjusting optical energy of at least one optical beam during the scanning based on (1) the location of the scanning optical beam and (2) the predetermined distortion information at the location.
