Abstract: A rotating display apparatus is provided. The rotating display apparatus includes a pixel array and a control device. The pixel array is capable of rotating around a rotation axis in the pixel array, the pixel array includes a plurality of pixel units, and the plurality of pixel units are arranged in a plurality of pixel columns distributed in a direction perpendicular to the rotation axis. Pixel units in each pixel column are arranged in a direction parallel to the rotation axis and operate at a same refresh frequency. A refresh frequency of pixel units in a pixel column close to the rotation axis is less than a refresh frequency of pixel units in a pixel column far away from the rotation axis. The control device is configured to control the pixel units in each pixel column to operate at a refresh frequency corresponding to the pixel column.
