    Abstract: A liquid crystal cell, a method of driving a liquid crystal cell, and a liquid-crystal-based spectacle lens are provided. The liquid crystal cell includes: a ring-like electrode layer, a liquid crystal layer, and an opposite electrode layer. The second ring-like electrode region is concentric with the first ring-like electrode region and surrounds the first ring-like electrode region; the first ring-like electrode region is configured to drive corresponding liquid crystal molecules in the liquid crystal layer, so as to form a first Fresnel zone plate region in the liquid crystal cell; the second ring-like electrode region is configured to drive corresponding liquid crystal molecules in the liquid crystal layer, so as to form a second Fresnel zone plate region of the liquid crystal cell; an order of the second Fresnel zone plate region is smaller than an order of the first Fresnel zone plate region.

    Abstract: The present disclosure provides a panel with a virtual curved display surface and a display device. The virtual curved display panel includes a display panel and a grating. The grating is disposed at a light-exiting side of the display panel, and includes a plurality of light-transmitting regions and a plurality of light-shielding regions spaced apart from each other. Respective widths of the plurality of light-shielding regions of the grating are gradually decreased as respective distances from the plurality of light-shielding regions to a symmetry axis of the display panel are increased, and respective widths of the plurality of light-transmitting regions are gradually increased as respective distances from the plurality of light-transmitting regions to the symmetry axis of the display panel are increased.
