Abstract: A virtual curved surface display panel and a display device are provided. The virtual curved surface display panel includes a flat display panel having a plurality of pixels arranged in a matrix, and an array of convex lenses arranged on a light exit surface of the flat display panel. The array of convex lenses makes a track of image distances of the pixels form a curved surface. By adjusting the focal lengths of the lenses, the image distances of the pixels in the flat display panel can be various. The images of the pixels are then distributed on a curved surface. A visual effect of a virtual curved surface can be achieved with a flat display panel, improving the effect of visual impact.

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.
