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.
