Abstract: A tiled interactive screen comprises a mounting surface and tiles mounted on the mounting surface. Each tile comprises a tile substrate with photoluminescent marks disposed in a pattern on or in the tile substrate. Each photoluminescent mark is unique with respect to every other photoluminescent mark on any of the tiles, each photoluminescent mark comprises a pattern encoding information specifying the location of the photoluminescent mark on the tile, and each tile substrate is at least partially transparent to light absorbed by the photoluminescent marks and is at least partially transparent to light emitted by the photoluminescent marks. The photoluminescent marks respond to stimulating electromagnetic radiation by emitting electromagnetic radiation.

Abstract: An artificial window is provided. In one example, the artificial window includes a transparent light emitting diode (LED) display panel, and a directional backlight module located at a back side of the transparent LED display panel. The transparent LED display panel includes multiple first LEDs to display at least one image frame, and the directional backlight module includes multiple second LEDs forming a directional LED array to generate a collimated directional light toward the transparent LED display. In another example, the artificial window includes a display panel to display at least one image frame; and a backlight module located at a back side of the display panel. The backlight module includes a first light source providing backlight for the display panel, and a second light source to generate a collimated directional light.

Abstract: A display device for displaying images in a rear projection display device is provided. The display device may include, amongst other structure, a screen including a lens portion and a frame portion. A tensioner may be operatively associated with the screen and may be adapted to adjust the frame portion to maintain a predetermined tautness in the lens portion.

Abstract: A display screen is provided. The display screen may be configured to receive an image from a display device, and includes a first surface with a topography configured to transmit light from the image, and a second surface configured with light reflecting portions and light absorbing portions. The light reflecting portions may be configured to substantially reflect light transmitted from the first surface, and the light absorbing portions may be configured to substantially absorb environmental light.

Abstract: A method and apparatus is provided in which a digital image is transmitted to a presentation projector resource over a wireless transmission medium using a reduced amount of transmission bandwidth by transmitting a subset of the digital image data. The subset image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. The subset image data may also be a scalable vector graphics representation of the subset of the digital image. Header data is provided to further describe the subset image data. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received.
