Abstract
Embodiments of apparatuses, methods and systems for deployable projection screens are generally described herein. Other embodiments may be described and claimed.
Claims15
A projection screen comprising:
- screen material having a perimeter and optical attributes suitable to facilitate viewing of images projected thereon;
- and
- a flexible frame having an axis dividing the flexible flame into a first and second portion, the flexible frame attached to the screen material substantially at said perimeter to support the screen material when the projection screen is in an expanded projection state, and the flexible frame being further sufficiently flexible to allow the projection screen to be twisted into a contracted storage state when transition forces are applied at a plurality of perimeter points, the projection screen in the contracted storage state occupying a surface area no more than 50% of a surface area occupied by the projection screen in the expanded projection state, the transition forces including two rotational forces applied to the first portion, the two rotational forces being applied in opposite directions about the axis.
A system comprising:
- a projection screen including
- screen material having a perimeter and optical attributes suitable to facilitate viewing of images projected thereon;
- and
- a flexible frame having an axis dividing the flexible flame into a first and second portion, the flexible frame attached to the screen material substantially at said perimeter to support the screen material when the projection screen is in an expanded projection state, and the flexible frame being further sufficiently flexible to allow the projection screen to be twisted into a contracted storage state when transition forces are applied at a plurality of perimeter points, the transition forces including two rotational forces applied to the first portion, the two rotational forces being applied in opposite directions about the axis;
- and
- a housing configured to house a projection device, to store the projection screen when in the contracted storage state, and to display the projection screen when in the expanded projection state in a manner to facilitate viewing of an image projected by the projection device.

A method comprising:
- untwisting a projection screen from a contracted storage state to an expanded projection state by applying transition forces to a plurality of perimeter points of a flexible frame of the projection screen, the flexible frame having an axis dividing the flexible flame into a first and second portion, screen material, having optical attributes suitable to facilitate viewing of images projected thereon, attached to the flexible frame substantially at a perimeter of the screen material;
- applying transition forces including applying two rotational forces to the first portion, the two rotational forces being applied to opposite directions about the axis;
- and
- projecting, with a projecting device, an image onto the projection screen while the projection screen is in the expanded projection state.
