Abstract
A double-sided display device includes: a first display layer, configured to implement output of a display signal of a first side; and a second display layer, configured to implement output of a display signal of a second side; a conversion layer positioned between the first display layer and the second display layer, which switches between a light-transmitting state and an opaque light-shielding state. The conversion layer is in the light-shielding state during a display phase, and in the light-transmitting state during an interfering phase which follows the display phase. During the interfering phase, the first display layer is further configured to output a first interfering signal to interfere with the image displayed by the second side, and the second display layer is further configured to output a second interfering signal to interfere with the image displayed by the first side.
