Abstract: A virtual curved surface display panel and a display device are provided. By using the light splitting principle of the grating structure, the imaging heights of the grating structures are designed to be symmetrically distributed with respect to a vertical symmetry axis of a display surface of the flat display panel. In the grating structures on the same side of the symmetry axis, the imaging heights of the respective grating structures having the same distance from the vertical symmetry axis are the same, and the imaging heights of the respective grating structures having different distances from the vertical symmetry axis are different from each other. By setting the imaging heights of the grating structures, the image distances of the pixels in the flat display panel are different so that the images of the plurality of pixels constitute a curved surface.

Abstract: A virtual curved surface display panel, a method of manufacturing the same, and a display device are provided. A set of vertical lenticular lens and horizontal lenticular lens fitted tightly and orthogonally is arranged on a light exit surface of a pixel in the flat display panel, which forms an equivalent spherical lens. The focal lengths of the equivalent spherical lenses are symmetrically distributed with a central pixel as a symmetry axis, and focal lengths of the equivalent spherical lenses in the columns located on the same side of the symmetry axis are not equal to each other. Therefore, the equivalent spherical lenses enable the images of the pixels to form a curved surface, thereby realizing virtual curved surface display.
