FIELD: engineering and manufacturing of rotary displays, in particular, large light diode type rotary displays for group use for visual indication.
SUBSTANCE: display contains control block, transfer/support mechanism, power supply, cylindrical video screen, consisting of light diode modules, each one of which represents vertically oriented hollow parallelepiped, inside of which the light diode matrix, controller and power supply for light diode matrix are installed.
EFFECT: improved quality of reproduced image, due to balancing of brightness of light diodes and stabilization of system of rotation of structure without increase in speed of rotation of display and number of used light diodes.
