Abstract: A visual display screen apparatus including a support member and a visual display screen for collapsible displays such as flexible projection screen systems and light-emissive screens screen systems in combination with the elongated support member. The elongated support member includes or consists of a strip of material having an arcuate cross-sectional shape and exhibiting sufficient rigidity to act as a support for the visual display screen. Within a region of the strip of material where it transitions from having an arcuate cross-sectional shape to a flat cross-sectional shape, the strip of material exhibits a significant reduction in its rigidity and can be readily bent for enabling rolling and/or folding of the elongated support member for enabling the visual display screen to be rolled, folded and/or collapsed for storage and transport.
