Paper Abstract

Wavefront-modulating (holographic) displays have the potential to become the ultimate 3D display, producing most of the visual cues necessary to experience depth. One of the main constraints in producing such displays is the high density of pixels that is required. Using gradient-index pixels (GrIPs), we show how the number of pixels, and hence the complexity of the display, may be reduced by orders of magnitude. With current liquid crystal display technology it is feasible to build such displays. The concept of the GrIPs may be applied to 2D displays, in which the amplitude rather than the phase is graded across each pixel. We show that these pixels have the potential to improve the image quality or reduce the pixel count in 2D displays.
