The invention relates to laser display system, especially laser TV, laser movie and larger screen laser display system indoor and outdoor. In the invention, laser is as light source, twin lamina of piezoelectric ceramic is as core part. Input video signal through separation circuit is separated into audio signal, tricolor signal, line scan signal and field scan signal. Modulated by accompanying sound circuit, audio signal drives speaker, generating sound. Passing through moderation circuit respectively, tricolor signals are transferred to three lasers to output tricolor lights. Separated line scan signal is projected to field scan device, and separated field scan signal through field scan signal modulation circuit and non-linear adjustment compensation circuit of field scan signal drives field scan device. Thus, straight line type signal laser on surface of the field scan device scan and projects light beam to screen so as to form a frame of laser video image.
