    Abstract: A light source color separation device and a display device are provided. The light source color separation device includes a plurality of sawtooth units and a light-emitting unit. The plurality of sawtooth units is arranged in an array. Each of the plurality of sawtooth units includes a plurality of sawteeth, and angles between working planes and bottom planes of the sawteeth in every two adjacent sawtooth units are different. The light-emitting unit is configured to irradiate the working planes of the plurality of sawteeth with parallel light at a certain incident angle, to make the light irradiated onto and then reflected by the working planes of the sawteeth in every two adjacent sawtooth units diffracted to have different colors.

    Abstract: Provided is a method for processing three-dimensional image data, applicable to providing three-dimensional image data to a three-dimensional display terminal, wherein the three-dimensional display terminal is provided with a plurality of viewpoints successively arranged, and a viewing region of the three-dimensional display terminal includes a plurality of sub-regions. The method includes: receiving indication information, wherein the indication information is indicative of a number of target sub-regions, the target sub-region being a sub-region, where a viewer is present, in the viewing region; determining a target view based on the indication information, wherein a number of the target views determined in a case that the number of the target sub-regions is 1 is less than the number of the target views determined in a case that the number of the target sub-regions is greater than 1; and transmitting image data of the target view to the three-dimensional display terminal.

    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.
