Abstract

The invention relates to light sources and displays incorporating blue laser pumped light sources that provide green light. According to a first aspect of the invention, a green light source includes a semiconductor diode laser emitting light in an optical path having a dominant wavelength within the blue spectral region, a substrate positioned in the optical path of the semiconductor diode laser, and a material coupled to the substrate. The material is selected to absorb light emitted by the semiconductor diode laser and, in response, to emit light having a dominant wavelength within the green spectral region. According to a second aspect of the invention, an apparatus includes a lighting module for a display, the lighting module includes an array of red laser light sources, an array of blue laser light sources, and an array of green light sources according to the first aspect of the invention.
