Claim:
1. A display, comprising: a modulating device; a plurality of light emitters arranged to illuminate modulating elements of the modulating device with a spatially modulated light according to image data, wherein, for each modulating element, there is a subset of the plurality of light emitters that illuminate the each modulating element; a controller configured to determine a set of intermediate samples comprising more samples than light emitters wherein each sample comprises a calculation based on the subset of the plurality of the light emitters and based on a point spread function of the subset of the light emitters, and wherein the controller determines a control signal for each modulating element of the modulating device based on a division of a portion of the image data and at least one sample corresponding to the portion of the image data, such that the division comprises a non-linear inversion of luminance values wherein the luminance values are tested prior to inversion whether the luminance values are above a desired threshold and, if not, the luminance values are clamped to the desired threshold; and said controller connected to the modulating device in a manner that energizes the modulating device according to the control signal such that the spatially modulated light from the plurality light emitters spreading together as determined in the set of intermediate samples is further modulated.
