Laser display device employing blue laser diode

A laser display device comprising:

• a plurality of subunits, each of the plurality of subunits including a light source configured to emit at least one laser beam and a scanning unit configured to perform a scanning with the at least one laser beam;
• and
• an image forming unit including a plurality of regions corresponding to the plurality of subunits, each of the plurality of regions being configured to generate excitation light and scattering light by receiving the at least one laser beam from each of the plurality of subunits to form an image,
• wherein the image forming unit comprises a plurality of pixels including a phosphor for generating excitation light and a light scattering region for generating scattering light,
• wherein the light source is a blue laser diode,
• wherein the phosphor comprises a red phosphor, and a green phosphor and the phosphor does not comprise a blue phosphor,
• wherein the scanning unit includes a first scanner and a second scanner configured to perform a first and secondary scanning, respectively, and
• wherein each of the first scanner and the second scanner includes at least one two-dimensional scanner.
