1. A mixed reality display system, comprising:
a transparent display, through which users on both sides see each other;
a plural pairs of shutter glasses worn by the users, each pair of shutter glasses being composed of a left glass and a right glass; and
a controller that synchronizes the transparent display and the shutter glasses;
wherein the transparent display displays content on its own;
wherein first-side shutter glasses worn by first-side users and second-side shutter glasses worn by second-side users are turned on in turns;
wherein the shutter glasses are controlled to turn on or off by pulse-width modulation (PWM) signals respectively, and a duty cycle of a PWM signal for first-side shutter glasses is different from a duty cycle of the PWM signal for second-side shutter glasses to compensate different luminances on different sides of the transparent display.
