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.

Abstract: The present disclosure discloses an array substrate, a display panel and a display device. The array substrate includes gate regions, gate lines, data lines, pixel electrodes and common electrode lines. The common electrode lines and the gate lines have the same extension direction, the pixel electrodes are located in regions defined by adjacent gate lines and adjacent data lines, the gate lines traverse the gate regions in the extension direction that are located in the same row as the gate lines, and the pixel electrodes have a gap from the gate lines at ends thereof closer to the gate lines. As such, a portion of the gate region that extends to the pixel region has a reduced area and hence a reduced edge length. This way, during the cleaning of the active layer after formation, less active layer metal may remain at the edges of the gate region. Thereby, the array substrate fabrication process is improved, and a product yield rate of the array substrate is increased.
