  • Patent number: 11956994
    Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.
