Abstract

The present invention provides 3D glasses and a 3D display system. The 3D glasses includes: a first glass, a second glass, a control device, a power supply unit, and an adjusting device. The first glass is utilized for receiving left eye image. The second glass is utilized for receiving right eye image. The control device includes: a duty cycle unit and a control unit. The duty cycle unit is utilized for providing a duty cycle, and the control unit is utilized for controlling the first glass and the second glass whether to be pervious to light or not. The power supply unit is coupled to the control device, and utilized for providing power. The adjusting device is coupled to the control device, and utilized for adjusting the duty cycle provided by the duty cycle unit according to a user input.
