A method comprising: receiving image data for image frames; controlling, based on the image data, a light source to emit a first light to irradiate a light conversion material configured to illuminate an image rendering surface; emitting, with the light conversion material, a second light to render at least a portion of the image frames on the image rendering surface; wherein the second light is excited by the first light, the light conversion material includes quantum dots, the second light is non-coherent light, characterized in that the received image frames are stereoscopic image frames; and in that the quantum dots are disposed in a two dimensional array to form a plurality of pixels, each pixel in the plurality of pixels comprises a first and a second type of quantum dots, wherein the first type and second type quantum dots are each configured to impart one of two or more different red colors with non-overlapping wavelengths, the two or more different red colors respectively being associated with either a left image block or a right image block of the stereoscopic image frame; wherein the first light comprises two or more mutually non-overlapping wavelength ranges, wherein each of the mutually non-overlapping wavelength ranges corresponds to one of two or more different colors, and wherein the first light in a first mutually non-overlapping wavelength range, in the mutually non-overlapping wavelength ranges, irradiates the first type of quantum dots at a same time as the first light in a second different mutually non-overlapping wavelength range, in the mutually non-overlapping wavelength ranges, irradiates the second different type of quantum dots. receiving image data for image frames; controlling, based on the image data, a light source to emit a first light to irradiate a light conversion material configured to illuminate an image rendering surface; emitting, with the light conversion material, a second light to render at least a portion of the image frames on the image rendering surface; wherein the second light is excited by the first light, the light conversion material includes quantum dots, the second light is non-coherent light, characterized in that the received image frames are stereoscopic image frames; and in that the quantum dots are disposed in a two dimensional array to form a plurality of pixels, each pixel in the plurality of pixels comprises a first and a second type of quantum dots, wherein the first type and second type quantum dots are each configured to impart one of two or more different red colors with non-overlapping wavelengths, the two or more different red colors respectively being associated with either a left image block or a right image block of the stereoscopic image frame; wherein the first light comprises two or more mutually non-overlapping wavelength ranges, wherein each of the mutually non-overlapping wavelength ranges corresponds to one of two or more different colors, and wherein the first light in a first mutually non-overlapping wavelength range, in the mutually non-overlapping wavelength ranges, irradiates the first type of quantum dots at a same time as the first light in a second different mutually non-overlapping wavelength range, in the mutually non-overlapping wavelength ranges, irradiates the second different type of quantum dots.
