A laser projector has a cursor control unit, a main control unit, a laser generator and a scanning lens. The cursor control unit is used to generate and transmit cursor signals; the main control unit is used to obtain and process video signals and the cursor signals, both of which are combined into cursor video signals and transmitted; the laser generator is coupled to the main control unit for generating and projecting laser beam according to the cursor video signals; and the scanning lens is coupled to the main control unit for receiving the laser beam and projecting it outward in a predetermined scanning manner. The laser projector of the present invention uses laser resource itself to project laser cursor generated by the cursor control unit onto a screen, so that it is unnecessary to additionally use a laser pointer, and the operation of the laser projector is relatively simple. |
