    摘要: An AR optical system includes a depth-of-field separation structure corresponding to an image source, configured to convert light rays emitted from the image source into a plurality of light beams with different depths of field; a convergent lens located on an emergent light path of the depth-of-field separation structure, and configured to receive and shape the plurality of light beams with different depths of field; a first semi-transmitting semi-reflecting mirror located on a side, away from the depth-of-field separation structure, of the convergent lens, and configured to reflect the plurality of shaped light beams with different depths of field towards a set direction; a concave mirror having a preset transmission-reflection ratio configured to reflect and converge the plurality of light beams with different depths of field and then make the light beam incident to a set observation position after passing through the first semi-transmitting semi-reflecting mirror.

    摘要: A display device includes a base substrate, a display panel, and a moveable structure located between the base substrate and the display panel, fixedly connected to the display panel and slidably connected to the base substrate; the display panel includes pixel areas and non-pixel areas between the pixel areas; in displaying phase, the moveable structure is configured to control the display panel to perform reciprocating motion with a preset cycle, the distance that the display panel moves in a single direction in the preset cycle is smaller than or equal to the width of a non-pixel area in the single direction, the preset cycle is the time required for the display panel to perform reciprocating motion once, and the time that the display panel moves in the single direction in the preset cycle is equal to the time that an image of the display panel is refreshed once.

    摘要: The present disclosure provides an optical lens, glasses and a display device. The optical lens includes: a first surface, a second surface, a first lens portion and a second lens portion. The optical lens is a convex lens. The first surface and the second surface are at two side surfaces of the optical lens. The first surface is a convex aspheric surface, and the second surface is a Fresnel surface with a recessed curved base. The first lens portion and the second lens portion are adjacent each other and connected in a direction perpendicular to a main optical axis of the optical lens. A first focal point of the first lens portion and a second focal point of the second lens portion are on the main optical axis, and a focal length of the second lens portion is greater than a focal length of the first lens portion.
