Title: Rolling light emitting diode screen device

Abstract: A rolling light emitting diode screen device includes a plurality of equilong rigid supporting stripes, a plurality of 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. It is characterized that it further includes a flexible frame, and the plurality of 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 strips and the pixel units thereon to roll around an axis parallel to the axis of the rigid supporting stripes to form a reel. The rolling LED screen device of the invention is easy to be stored, transported and mounted, wirings thereof are easy to be disposed, not easy to be damaged, and easy to repair.
