1. A display device, the device comprising:
a display surface;
a monochromatic image generator configured to generate monochromatic visual information for display at the display surface, wherein the monochromatic image generator reflects light from a primary light source using a transflective spatial light modulator;
a spatially addressable backlight generator configured to backlight the transflective spatial light modulator, wherein the spatially addressable backlight generator includes an array of colored light sources that are driven to selectively emit light toward a non-reflective side of the transflective spatial light modulator to infuse colored light into the monochromatic visual information generated by monochromatic image generator, thereby resulting in infused color information being presented at the display surface with the monochromatic visual information; and
one or more processors configured to:
determine the infused color information to present on the display surface, and
control the colored light sources in the spatially addressable backlight generator to emit light toward the non-reflective side of the transflective spatial light modulator to effectuate the presentation of the infused color information.
