Three-dimensional display device and operation method thereof

A three-dimensional display device, comprising:

• an eye tracking device for providing left eye image data and right eye image data;
• a first processing unit coupled to the eye tracking device and calculating coordinates of a left viewpoint and coordinates of a right viewpoint based on the left eye image data and the right eye image data;
• a display for displaying an image and comprising:
• a plurality of light-emitting units for emitting a plurality of light beams;
• and
• a plurality of light-splitting units for distributing the plurality of light beams to the left viewpoint and the right viewpoint;
• and
• a second processing unit coupled to the first processing unit and the display,
• wherein the second processing unit defines a crosstalk region based on an opening angle and optical paths of the plurality of light beams passing through the plurality of light-splitting units, the crosstalk region is simultaneously struck by a first light beam among the plurality of light beams assigned to the left viewpoint and a second light beam among the plurality of light beams assigned to the right viewpoint, and the second processing unit compares a first preset gray level corresponding to the first light beam and a second preset gray level corresponding to the second light beam to determine a first corrected gray level corresponding to the first light beam and a second corrected gray level corresponding to the second light beam,
• wherein the first preset gray level is L, the second preset gray level is R, the first corrected gray level is L′, the second corrected gray level is R′, a correction parameter is α, and the three-dimensional display device satisfies:
• L′=L−|(L−R)|*(1−α), and
• R′=R−|(L−R)|*(1−α), wherein 0≤α≤1.
