Patent ID: 8052280

Claim:
A laser display device comprising: a laser light source for emitting a laser light; a modulator for modulating the laser light emitted from the laser light source and emitting a modulated light; a branching unit for branching the modulated light emitted from the modulator into at least two branched lights, such that the at least two branched lights are emitted from the branching unit; and an optical path setting unit for setting optical paths of the at least two branched lights emitted from the branching unit, such that the emitted at least two branched lights propagate toward a screen, wherein the optical path setting unit causes the emitted at least two branched lights to reach same positions on the screen at substantially same timings by way of different optical paths set by the optical path setting unit, and wherein the optical path setting unit scans the emitted at least two branched lights on the screen to reach one of the same positions at substantially a same time and then to reach another of the same positions at substantially another same time.
