Sequential light field display
A sequential light field display is a type of light field display that uses a light source array.
It does not display a full light field all at once. Instead, it displays parts of it in rapid succession.
It typically reflects light off of a high speed binary display, such as a DMD.[1]
They exploit persistence of vision in the human visual system to allow for a much lower bandwidth requirement. They dither color and depth information.
Sequential light field displays use novel techniques.
Andrew Maimone developed this.[1]
The light source is directional. So one LED lights up in the backlight array, which sends light through a pinhole onto the DMD, but it is not centered on the DMD. The DMD must change where it is displaying an image's focal segment in the XY plane of the display according to which backlight LED is lit. For example, a leftmost LED would mean the DMD should have a pattern more on the right side of the DMD.
