An interactive propaganda display system based on an ARM processor

Abstract

The application discloses an interactive propaganda display system based on an ARM processor, which comprises a main display and a sub-display, an arc-shaped outer wall of the main display is provided with a surrounding groove, the sub-display is connected with the surrounding groove through a limiting mechanism, both sides of the main display are provided with supporting rods, both of the supporting rods are L-shaped, and the horizontal parts of both of the supporting rods are provided with openings. Through the arrangement of the main display, the sub-display, the limiting mechanism, the surrounding motor and the surrounding mechanism, the stable connection of the sub-display and the main display can be realized without separation by means of the connecting groove and the surrounding block, then the surrounding movement of the sub-display relative to the main display is realized by the cooperation of the surrounding motor driving the surrounding gear rotating rod and the cooperation of the fixed ring, the multi-angle text pattern rotating display effect can be realized, and after the sub-display is rotated and adjusted from the uppermost position to the lowermost position, the wiping and cleaning operation on the surface of the sub-display is facilitated.
