A rotating display to present images includes a transmission/support mechanism installed on a column of a building, an annular display unit installed around the column, supported and driven by the transmission/support mechanism, a contact power supply unit installed on the column, a control unit provided inside the display unit, and an angle encoding unit between the column and the display unit. Using the foregoing elements, a rotating display can be formed on a column of a building. Image signals are transmitted wirelessly to the control unit to light up the light-emitting modules on the display unit. Due to the visual persistence in human vision, a 360-degree panoramic image can be produced, thus decorating the building column or playing commercials.
