摘要： A front projection display device having a projection module and a docking station. The docking station has a base. Further, the docking station can include an extendable arm attached to the base. The projection module contains an optical engine. The optical engine includes an illumination system, an imaging system, and a wide-angle projection lens. The optical engine outputs an image at a half field angle of at least 45°. The projected image has substantially no distortion and requires substantially no keystone correction.

摘要： A front projection display device includes an optical engine including an illumination system, an imaging system, and projection optics. The projection optics include a first lens group of negative refractive power that has at least one aspheric surface. The projection optics output an image at a half field angle of at least 45°, where the image has substantially no distortion. For example, when the first lens group is placed at a distance of less than 1 meter from a viewing screen, the output image has a size of about 40 inches diagonal or greater, and requires substantially no keystone correction. In other aspects, the optical engine can be implemented in a wall-mounted projection system, a multimedia system, a compact integrated monitor system, and a portable projection unit.

摘要： A portable projection device comprises a housing, a handle, and an optical engine. The optical engine comprises an illumination source, an imaging system, and a wide angle projection lens that includes a first lens group of negative refractive power, the first lens group having at least one aspheric surface, a second lens group, and a third lens group of positive refractive power. For the wide angle projection lens, the following Conditions (1) to (4) are satisfied: |F1/F|≧4.5 (Condition (1)); 2.5≦|F2/F|≦6.0 (Condition (2)); 3.8≦|F3/F|≦5.0 (Condition (3)); and 0.8≦BFL/F≦1.4 (Condition (4)). The portable projection device can be implemented as a personal gaming system and can also be configured as a portable, fully integrated video gaming system that allows gamers to plug in and play at nearly any location, with only a wall or other viewing surface being used to view the projected image.

摘要： A front projection screen and associated system and method are disclosed that utilize a back structured layer and a front diffusing layer to provide improved viewable image quality. The structured layer is formed with a plurality of grooves and can operate to direct light into a defined audience view region. The diffusing layer is coupled to the structured layer and is formed from a matte polyester film to provide dry erase capability on a front surface of the diffusing layer. For example, the matte polyester film can be TEKRA Marnot XL matte Melinex polyester film. Further, the structured layer can be formed as an acrylate linear prismatic structure having a gloss white coating. The acrylate linear prismatic structure and the matte polyester film can be coupled, for example, by lamination or can be coupled by being extruded as a unitary construction.
