Abstract: A laser projection system including a projection screen and a laser projector is revealed. The projection screen includes at least one light emitting layer having at least one luminescent material that is excited by excitation light with a specific wavelength range to generate excited light with another wavelength range. The laser projector consists of a laser light source module, a laser signal modulation module, a rotation plane mirror module, a rotation plane mirror control module, and a signal conversion module. The laser projector produces excitation laser according to an image signal of a static image or dynamic image and projects the laser to the projection screen correspondingly for an image displayed. Thus a projected image with high recognition is displayed on the projection screen in a transparent manner in natural sunlight. Therefore efficiency and application of the laser projection are improved.
