    Abstract: Provided is a near-eye display apparatus, comprising: a first display (11), used for displaying a first image, entering a beam splitter (30) by means of a first imaging lens (12); a second display (21), used for displaying a second image, entering the beam splitter (30) by means of a second imaging lens (22), the beam splitter (30) being used for transmitting the imaging light beam of the first imaging lens (12) and reflecting the imaging light beam of the second imaging lens (22); a waveguide plate (40), located on the light exit path of the beam splitter (30), and used for receiving outgoing light from the beam splitter (30) and transmitting same; the waveguide plate (40) is internally provided with a light-taking component (400), the light-taking component (400) being used for reflecting the imaging light beam transmitted in the waveguide plate (40) toward a position where a human eye is located. The image distances of the first imaging lens (12) and the second imaging lens (22) are different, thus it is possible to display the first image and the second image on two image planes, and, by means of adjusting the human eye, when observing an image of an image plane the image of the other image plane is blurry, which is consistent with a sensation of viewing an actual scene, thus eliminating vergence-accommodation conflict.

    Abstract: An optical displaying system, a controlling method thereof, and a displaying device, which relates to the technical field of displaying. The optical displaying system includes a display screen (1); a first light splitting unit (2), wherein after a light ray emitted by the display screen (1) passes through the first light splitting unit (2), the light ray is converted into a first-type polarized light or a second-type polarized light; an imaging unit (3), wherein after a light ray exiting from the first light splitting unit (2) passes through the imaging unit (3), the light ray forms an enlarged image corresponding to a first focal length; a second light splitting unit (4); a first optical-path unit (5), wherein after the first-type polarized light transmitted out of the second light splitting unit (4) passes through the first optical-path unit (5), the first-type polarized light forms an enlarged image corresponding to a second focal length, is converted into the second-type polarized light; and a second optical-path unit (6), wherein after the second-type polarized light reflected out of the second light splitting unit (4) passes through the second optical-path unit (6), the second-type polarized light is converted into the first-type polarized light.

    Abstract: This disclosure relates to a light modulation panel and a display device. The light modulation panel comprises: a color separation grating plate having a plurality of light-transmissive microstructures; a reception substrate located on a light exit side of the color separation grating plate and spaced away from the color separation grating plate; and an optical waveguide layer located on a light exit side of the reception substrate. According to technical solutions of this disclosure, the optical waveguide layer can modulate the exit light into collimated light. As a result, cross-color phenomenons of the display device can be effectively improved, and thereby the display quality is enhanced. In addition, by adjusting a structure of the optical waveguide layer, the exit light can also be emitted out at a preset angle such that the display device can be applied in occasions such as 2D display, 3D display or privacy protection.
