Three-dimensional display device and three-dimensional display method thereof

A three-dimensional (3D) display method, applicable to a 3D display device, which comprises:

• providing a first signal to the 3D display device sequentially for providing left-eye image and right-eye image sequentially;
• and
• providing a second signal at the time of switching the left-eye image and the right-eye image for inserting a black image
• wherein different 3D display quality being obtained through adjusting the insertion time of the black image.

A three-dimensional (3D) display device, which comprises:

• a display panel, for providing display image;
• a driver chip, for providing a first signal to the display panel sequentially for providing left-eye image and right-eye image sequentially, and providing a second signal at the time of switching the left-eye image and the right-eye image for inserting a black image:
• and
• a controller, for controlling the driver chip to adjust the insertion time of the black image to obtain different 3D display quality.
