Ultra-D uses a stack of layers of refractive and diffractive optical elements bonded to an display panel. The viewing areas are repeated horizontally with smooth transitions between them. The optical system creates an almost continuous light field in front of the screen.
I recall that I have read that the higher the resolution, the better/smooth is the light field that is generated by this layer.
Ultra-D combines a 2D image and a depth map, using the pixels on the screen for one or the other. For example, a 4K/UHD screen has 8 million pixels, half of which are used for the 2D image while the other half are used for the depth map.
At CES 2018, there was a 65″ custom-built flat panel with 16 million pixels in a 4K x 4K array. The 2D image was generated by 8 million pixels, and the depth map used the other 8 million pixels.
For a 8K panel the ratio it will probably be 8 million (4K/UHD) for the 2D image and 24 million for the depth map.
Yes, the early FHD/2K versions of the system were unimpressive, but starting with the 4K panels things got better.
Maybe 8K is what is needed for this tech to become more widespread...
