An enhanced-contrast projection screen and method of controlling such screens are disclosed. An embodiment of a dynamic projection screen includes a passive layer and at least one active layer. The active layer is superimposed on at least a portion of the passive layer and is adapted to selectively toggle between being transparent and being opaque. A method of controlling such a screen includes determining desired dimensions of a reflective region, and activating at least a portion of an active layer superimposed on at least a portion of a passive layer. The active layer is adapted to selectively toggle between being transparent and opaque.
