  • Patent number: 9823484
    Abstract: The disclosure relates to a 3D display device. The 3D display device includes a display panel and an electrochromic grating that is located on a light output side of the display panel; wherein the electrochromic grating comprises: a first transparent electrode layer, an electrochromic layer, a solid electrolyte layer and a second transparent electrode layer that are overlapped on a substrate of the display panel in sequence. As the solid electrolyte layer is used replacing the process in prior art that an upper and lower glasses substrates are used to package the electrochromic grating and thus avoiding complex packaging process, the 3D display device can be thinned. Further, as the electrochromic grating is directly formed on the substrate of the display panel, alignment between the electrochromic grating and the sub-pixels in the display panel can be more simple and accurate.

  • Patent number: 9615068
    Abstract: A method for generating three dimensional (3D) displays. The method includes displaying a hologram that combines three (or more) images encoded into three (or more) different OAM channels, and the method also includes reflecting light from the displayed hologram to create a multichannel light beam. Then, the method involves decoding the multichannel light beam to decode and display the three encoded images. The decoding step includes displaying the three encoded images in decoded form in three view zones, three focal planes, or on three spaced-apart planes. The decoding is performed by a single decoding screen using holograms used for generating the three encoded images or is performed by three decoding screens configured based on a differing one of the holograms used for generating the three encoded images. The displaying of the hologram step includes operating a spatial light modulator (SLM) to display the hologram on a screen of the SLM.
