Abstract: Display spectacles and a driving method thereof are disclosed. The display spectacles include a spectacle frame and two display devices provided on the spectacle frame as spectacle lenses. Each of the display devices includes a backlight, a lower substrate on a light exit side of the backlight, an upper substrate arranged opposite to the lower substrate, a liquid crystal layer located between the upper substrate and the lower substrate, a plurality of electrode structures located between the upper substrate and the lower substrate, and a control unit. During displaying, the electrode structure deflects liquid crystal molecules in the liquid crystal layer corresponding to the electrode structure to form a microprism structure. The control unit adjusts a voltage on the electrode structure, thereby controlling total internal reflection or refraction of the microprism structure for light emitted from the backlight, and the adjustment for display gray scale can thus be realized.
