  • Patent number: 11480789
    Abstract: A direct-retina holographic projection system includes first and second spatial light modulators (SLMs) and a control module. The first SLM receives a beam of light and dithers the beam of light at a predetermined frequency to provide multiple instances of the beam of light. The second SLM receives the instances of the beam of light, displays an encoded phase hologram of a graphic image to be projected, and diffracts the instances of the beam of light to provide instances of the encoded phase hologram with the same graphic image but multiplied with dithered wavefronts. The control module: iteratively adjusts a parameter of the first SLM to generate the instances of the beam of light; and controls operation of the second SLM to, based on the instances of the beam of light, display multiple instances of the graphic image on a retina of an eye of a viewer.

  • Patent number: 11475848
    Abstract: A display apparatus includes a first compensator, a second compensator and a display panel including pixels. The first compensator generates a first compensation coefficient based on sensing data of a pixel of the pixels for a first grayscale value, generates a second compensation coefficient based on camera imaging data for a second grayscale value greater than the first grayscale value and compensates image data based on the first compensation coefficient and the second compensation coefficient. The second compensator compensates the image data by modeling sensing data of entire grayscale range based on sensing data of the pixel for a third grayscale value and a fourth grayscale value. The display panel displays an image based on the image data compensated by the first compensator and the second compensator.
