Laser based display method and system

摘要

The present invention is directed to display technologies. More specifically, various embodiments of the present invention provide projection display systems where one or more laser diodes are used as a light source for illustrating images. In one set of embodiments, the present invention provides projector systems that utilize blue and/or green laser fabricated using gallium nitride containing material. In another set of embodiments, the present invention provides projection systems having digital lighting processing engines illuminated by blue and/or green laser devices. In one embodiment, the present invention provides a 3D display system. There are other embodiments as well.

1. A method for operating a projection apparatus comprising:
providing the projection apparatus comprising:
a housing having an aperture;an input interface for receiving one or more frames of images;a laser source including an edge emitting blue laser diode and a wavelength modifying module, the blue laser diode comprising a gallium and nitrogen containing material, the wavelength modifying module comprising phosphor material, the laser exciting the phosphor material to form a colored emission source;a digital light processing chip comprising a digital mirror device, the digital mirror device including a plurality of mirrors, each of the mirrors corresponding to one or more pixels of the one or more frames of images;means for directing light from the blue laser diode and the colored emission sources to the digital mirror device; anda power source electrically coupled to the laser source and the digital light processing chip; and projecting an image using the projection apparatus.
