Abstract

The embodiment of the invention relates to the field of optical display, and discloses a naked eye 3D display optical device and a naked eye 3D display system. The naked-eye 3D display optical device comprises a diaphragm layer and at least one lens array layer, the diaphragm layer comprises a light-transmitting area and a shading area which are arranged at intervals, each lens array layer in the at least one lens array layer comprises a lens assembly, and the lens assembly comprises a plurality of lens areas which are arranged at intervals. Wherein the light-transmitting areas of the diaphragm layer are in one-to-one correspondence with the lens areas of any lens array layer, and the aperture of each light-transmitting area in the diaphragm layer is smaller than or equal to the aperture of the lens area corresponding to the light-transmitting area in the diaphragm layer when the central points are on the same straight line. According to the naked-eye 3D display system adopting the naked-eye 3D display optical device in the technical scheme, through filtering of the diaphragm layer, it can be ensured that light in 3D display is light with relatively small aberration, so that the influence of the aberration on a 3D display image can be reduced, and the definition of the naked-eye 3D display image is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of optical technologies, and in particular, to a naked-eye three-dimensional (3Dimension, 3D) display optical device. Background technique [0002] Glasses-free 3D display refers to a display technology in which a user can directly view an image with a 3D display effect at the display source without wearing any auxiliary equipment. The principle of naked-eye 3D display is that after the light of the display source is modulated by the optical device, the user's left eye and right eye can see two images with parallax, and the parallax image enables the user to see an image with a 3D display effect. [0003] Conventional 3D display devices obtain images with 3D display effects through lens array processing, such as figure 1 As shown, each lens in the lens array modulates the light incident from the display source to output the modulated light to the human eye, and the image formed by the modu...
