Abstract: A display apparatus comprises of at least two stationary rotating units, which are parallel and spaced apart from each other and housed in a rigid frame with at least one opening formed as a viewing window. A flexible web is wrapped around these two rotating units, forming at least one moving viewing plane in the opening of the rigid housing. There are at least one line of light emitting elements arranged parallel to the rotating units and travels constantly through the display opening. A control unit inside the housing provides power, display data and control signal to the light emitting elements on the moving web; A communication unit provides the necessary link between the control unit and the moving web so that power, display data and control signal can be passed on to the light emitting elements causing them to display either text, or video image on the moving web, which can be viewed through the opening of the housing, thus creates a single-face display apparatus.

Abstract: A monochromic, multi-color and full-color cold cathode fluorescent display (CFD), comprises of: some shaped white or multi-color or red, green, blue three primary color cold cathode fluorescent lamps (CCFL), reflector, base plate, temperature control means, luminance and contrast enhancement face plate, shades and its driving electronics. CFD is a large screen display device which has high luminance, high efficiency, long lifetime, high contrast and excellent color. CFD can be used for applications both of outdoor and indoor even at direct sunlight, to display character, graphic and video image.
