Abstract:
1. A display, comprising: an array of light sources comprising a plurality of sets of the light sources; a zonal controller configured to energize at least one of the sets of light sources; and a modulating panel; wherein: each set of light sources are configured to produce a zonal illumination on the modulating panel and the modulating panel is configured to further modulate the zonal illuminations in a manner to produce a desired image; the zonal illuminations are based on image data and the further modulation of the zonal illuminations are based on a light field simulation of the zonal illuminations and the image data; the light field simulation comprises a summation of individual zonal illuminations' effect on pixels of the modulating panel; and the light field simulation comprises an output tristimulus value for each pixel vector r, comprising: where: X(r), Y(r), and Z(r) comprise tri-stimulus values target outputs in front of the display at a particular pixel position vector r; PSF(r−r x [P] [X Y Z] P wherein the linear LCD drive values comprise:
