Patent ID: 8427590

Claim:
A projection apparatus comprising: a housing having an aperture; an input interface for receiving one or more frames of images; a video processing module; a laser source, the laser source including an edge emitting blue laser diode, an edge emitting green laser diode, and an edge emitting red laser diode, the blue laser diode and the green laser diode sharing a first mounting surface, the green laser diode having a wavelength of about 490 nm to 540 nm, the laser source being configured to produce a laser beam by combining outputs from the blue, green, and red laser diodes, wherein the blue laser diode and the green laser diode are fabricated using a gallium and nitrogen containing material; a laser driver module coupled to the laser source, the laser driver module being configured to generate three drive currents based on a pixel from the one or more frames of images, each of the three drive currents being adapted to drive a laser diode; a MEMS scanning module configured to project the laser beam to a specific location through the aperture; an optical member provided within proximity of the laser source, the optical member being adapted to direct the laser beam to the MEMS scanning module; and a power source electrically coupled to the laser source.
