ある。DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, a plurality of laser beam projectors each having a different emission color are arranged, and the rays are condensed in synchronism with a projection screen or the like. This is a color display device that can obtain colors. Also, the present invention moves the focal point arbitrarily,
By scanning the screen, a two-dimensional image can be projected.

Bright spots and images can also be projected on floating surfaces such as building walls and smoke. Referring to the drawings, a video signal 1 input to the device is processed by a main controller 2 and separated as luminance information of each color, and a laser light emitting device controller 3 operates a laser light emitting device 4 of each color,
The screen 1 emits a laser beam 8 according to the input information.
Project to 0. When scanning the bright spot of a laser beam,
By operating the polygon mirror 5 attached to each color laser light emitting device 4 using the polygon mirror driving device 8, the bright spot 9 of the laser beam 8 can be freely moved. In addition, since the polygon mirror driving device 7 is synchronized with the laser driving device 4 of each color by the main controller via the polygon mirror driving device controller 6, after scanning at high speed, the afterimage of the eyeball of the person who sees the bright spot. By utilizing the phenomenon, it can be recognized as a two-dimensional image such as a photograph.
