Abstract: A display device is disclosed. The display device includes a display panel, and a grating layer arranged inside or outside of the display panel. Along a direction pointing from a center of a sight concentration area of the display device to a non-sight concentration area of the display device, a grating period of the grating layer decreases gradually. When incident light incident on the grating layer is diffracted at an area of the grating layer corresponding to the non-sight concentration area of the display device, the obtained light of non-zero order diffraction falls into a sight of a viewer.

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.
