Virtual curved surface display panel and display device
A virtual curved surface display panel and a display device are provided. By using the imaging principle of the concave lens, the concave lens array is provided on the display surface of the flat display panel, and the focal lengths of the concave lenses are designed to be symmetrically distributed with respect to a vertical symmetry axis of the display surface. In the concave lenses on the same side of the symmetry axis, the focal lengths of the respective concave lenses having the same distance from the vertical symmetry axis are the same, and the focal lengths of the respective concave lenses having different distances from the vertical symmetry axis are different from each other. By setting the focal lengths of the concave lenses, 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.
