    Abstract: An optical system has an optical axis, and includes a positive focal power lens, a negative focal power lens and a display. The positive focal power lens includes a first convex surface away from the display and a second convex surface proximate to the display. The negative focal power lens includes a third convex surface away from the display and a fourth concave surface proximate to the display. For a refractive index of the positive focal power lens and a refractive index of the negative focal power lens, one is greater than another, and a greater refractive index is a first refractive index, a smaller refractive index is a second refractive index, the first refractive index is greater than 1.7, the second refractive index is greater than 1.5, and a ratio of the first refractive index to the second refractive index is less than or equal to 2.

    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 system, a display apparatus, and smart glasses are provided. The optical system includes a transflective element, a reflective element and a plurality of microstructures. The transflective element is configured to reflect collimated incident light to the reflective element. The reflective element is configured to reflect the collimated incident light back to a light incident surface of the transflective element, so as to adjust an angle at which the collimated incident light exits. The transflective element is further configured to transmit the reflected-back collimated incident light to a target region. The plurality of microstructures are configured to adjust angles at which ambient stray light incident on surfaces thereof exits, and to scatter the ambient stray light out of the target region.

    Abstract: A head-up display system and a display apparatus are provided in this disclosure, which relates to a technical field of displaying. The head-up display system includes a display unit; a light splitting unit provided on a light emitting side of the display unit and configured to transmit a first linearly polarized light and block a second linearly polarized light, light emitted by the display unit being converted into the first linearly polarized light after passing through the light splitting unit; a light-transmitting substrate; a first imaging unit provided on an optical path from the light splitting unit to the light-transmitting substrate and configured to be able to transmit and reflect the first linearly polarized light; and a second imaging unit provided on a side of the light-transmitting substrate away from the first imaging unit, and configured to reflect the first linearly polarized light transmitted through the light-transmitting substrate.
