Abstract:
An arrayed waveguide, a display device, and a spectacles device are disclosed. The arrayed waveguide includes a first waveguide layer and a second waveguide layer stacked. The first waveguide layer includes a first main expanding portion having a plurality of first optical medium layers configured to expand, in the first direction, the first light beam incident into the first main expanding portion and reflect it towards the second waveguide layer. The second waveguide layer includes a second main expanding portion having a plurality of second optical medium layers configured to expand, in the second direction, the second light beam incident into the second main expanding portion and reflect it to exit from a side of the second waveguide layer away from the first waveguide layer. The second main expanding portion is further configured to transmit the expanded first light beam therethrough.
Abstract:
The present disclosure discloses a hologram recording device and a hologram recording method. The hologram recording device comprises an object imaging unit comprising a cavity for accommodating an object whose interior wall is a reflective surface, and a light modulating unit configured to produce incident light and reference light interfering with the incident light and to direct the incident light to the object imaging unit. The cavity is provided with an imaging aperture for imaging of the object and at least one light incidence aperture for allowing the incident light to enter the cavity and irradiate on the object, such that an image of the object is formed at a location corresponding to the imaging aperture outside the cavity, and image light produced upon the imaging of the object interferes with the reference light at the location for recording of an image surface hologram.
Abstract:
The present application discloses a display apparatus. The display apparatus includes a display panel and an optical main body. The display apparatus has a first eyepiece side for viewing image on a first objective side of the display apparatus, and a second eyepiece side for viewing image on a second objective side of the display apparatus. The optical main body includes a first lens on a light emitting side of the display panel, and a transflective mirror between the first eyepiece side and the first objective side of the display apparatus and between the second eyepiece side and the second objective side of the display apparatus.
Abstract:
Embodiments of the present disclosure disclose a display device, a display method and a head-mounted virtual display helmet. The display device includes: a display panel; and a first lens having a first focal length, a spatial filtering component configured for filtering and a second lens having a second focal length which are arranged in order at a light exit side of the display panel, wherein the second focal length is different from the first focal length.
Abstract:
Embodiments of the present invention provide an array substrate, an optical grating, a display panel and a display device, so as to enable displaying different images in different directions in accordance with the arrangement of subpixels on the array substrate. Moreover, since in one direction only an image corresponding to said direction can be viewed, it would not be influenced by images displayed in other directions. The array substrate comprises a plurality of pixel groups, each pixel group comprises a first category of subpixel group for displaying a preset gray scale and a second category of subpixel group for displaying images of multiple viewpoints; wherein the second category of subpixel group may comprise a first subpixel group, a second subpixel group, a third subpixel group and a fourth subpixel group for displaying a first viewpoint image, a second viewpoint image, a third viewpoint image, and a fourth viewpoint image, respectively; the first subpixel group and the third subpixel group are adjacent to the first category of subpixel group in the vertical direction; the second subpixel group and the fourth subpixel group are adjacent to the first category of subpixel group in the horizontal direction.
Abstract:
The present disclosure provides a processing apparatus of device status change, including processor configured to: in response to detecting one or more status changes of at least one device, judging whether each status change would cause an update conflict of status information corresponding to the each status change, in a management user interface of the at least one device; store a management user interface update task corresponding to a status change that would not cause the update conflict into a current execution queue, and store a management user interface update task corresponding to a status change that would cause the update conflict into a delayed execution queue; and in the case where the update conflict corresponding to the management user interface update task in the delayed execution queue has ended, execute the management user interface update task corresponding to the update conflict in the delayed execution queue.
Abstract:
Image processing method and device for a spliced panel and a spliced panel are provided. The image processing method includes calculating a horizontal stretch coefficient of the spliced panel according to a resolution of the plurality of display units, a sum of horizontal spliced-gap widths of the spliced panel and a horizontal pixel pitch of the plurality of display units; calculating a vertical stretch coefficient of the spliced panel according to the resolution of the plurality of display units, a sum of vertical spliced-gap widths of the spliced panel and a vertical pixel pitch of the plurality of display units; stretching an original image to be displayed by the spliced panel according to the horizontal stretch coefficient and the vertical stretch coefficient to acquire a target image; and controlling display of the plurality of display units of the spliced panel according to the target image.
