Abstract: Techniques for optimizing light output profiles in display systems are described. A light output profile is defined in relation to a plurality of sample locations on an illuminated surface. Point spread functions that satisfy illumination performance values specified in the light output profile in aggregate are computed or derived. A design process that adds or removes optical components to a display light assembly derives an optimal design of a light illumination layer for display systems. Relationships and parameter values determined in the design process may be configured into display systems along with the optical components for the purpose of generating optimized light output profiles in the display systems.

Abstract: Methods and apparatus are provided for backlighting a dual modulation display device. Each type of light source comprises a multi-primary light source having two or more primary color light emitters having different primary color characteristics from corresponding primary color emitters of other types of light source. Methods may comprise receiving illumination target values for a plurality of locations on the front modulator corresponding to the plurality of light sources, each of the locations on the front modulator configured to be illuminated by two or more of the plurality of light sources, determining primary color drive values source based on the primary color characteristics for that primary color and the illumination target value for the location corresponding to that light source, and driving the primary color light emitters or each type of light source based on the primary color drive values.
