Abstract:
1. A rolling light emitting diode screen device comprising one or more equilong rigid supporting stripes, one or more pixel units which are disposed with a equal interval in a straight line on the rigid supporting stripes, electric signal lines and power lines connected to respective pixel units, and a control device, a flexible frame with a rigid supporting stripe, and said rigid supporting stripes are aligned at both ends, and are disposed parallel with an equal interval on the flexible frame, so that a pixel matrix plane is formed on the rigid supporting stripes, the flexible frame engages the rigid supporting stripes and pixel units thereon to roll around an axis parallel to the axis of the rigid supporting stripes to form a reel, and tracks on a rigid fixing frame, with the ends of the rigid supporting stripes being disposed on the rolling screen and can move vertically along the tracks.
