Abstract
A rotary display device includes a display module, a rotating shaft, a transmission apparatus, an acquisition apparatus and a control apparatus. The transmission apparatus is configured to drive the display module to rotate with the rotating shaft. The control apparatus is configured to: receive information of picture(s), acquired by the acquisition apparatus, of an outside of the display module and determine whether a picture includes face figure(s); if no face figure is included in the picture, control the display module to display images in a first condition; if the face figure(s) are included in the picture, control the display module to display images in a second condition. A second refresh rate in the second condition is greater than a first refresh rate in the first condition, and a second color depth in the second condition is greater than a first color depth in the first condition.
