1. A display system, comprising: a plurality of light source components that are configured to emit a first light; and a light converter configured to be illuminated by the first light to convert the first light into second light, the second light comprising a mixture of two or more primary color components, and to illuminate pixels in one or more light modulation layers with the mixture of two or more primary color components; wherein the mixture of two or more primary color components comprises light of a first primary color and light of one or more second primary colors; wherein the light of the first primary color in the second light is generated by a first type of light conversion materials in the light converter that convert a first portion of the first light emitted by a first set of light source components in the plurality of light source components; wherein the light of the one or more second primary colors in the second light is generated by one or more second types of light conversion materials in the light converter that convert one or more second portions of the first light emitted by a second set of light source components in the plurality of light source components; wherein the first type of light conversion materials in the light converter is separate in space from the one or more second types of light conversion materials in the light converter; wherein an intensity of the first portion of the first light emitted by the first set of light source components in the plurality of light source components to illuminate the first type of light conversion materials is controlled separately from intensities of the one or more second portions of the first light emitted by the second set of light source components in the plurality of light source components to illuminate the one or more second types of light conversion materials; wherein the light converter represents a layer separate from the one or more light modulation layers.
