Three-dimensional display device and display method

A three-dimensional display device, comprising:

• an eye tracking device, configured to track a left eye position and a right eye position;
• a processor, coupled to the eye tracking device and configured to calculate a plurality of left eye viewpoints and a plurality of right eye viewpoints according to the left eye position and the right eye position and generate a plurality of views;
• and
• a display, coupled to the eye tracking device and the processor and comprising:
• a plurality of light emitting units, configured to emit a plurality of beams of light;
• and
• a plurality of light splitting units, configured to distribute a plurality of beams of light emitted by the plurality of light emitting units,
• wherein the processor calculates opening angles and light paths of the plurality of beams of light emitted by the plurality of light emitting units passing through the plurality of light splitting units to generate viewpoints through which the plurality of beams of light pass,
• wherein at least one beam of the plurality of beams of light passes through at least one of the plurality of left eye viewpoints and at least one of the plurality of right eye viewpoints simultaneously, and
• wherein the processor performs a light intensity comparison and post-processing on views corresponding to the at least one of the plurality of left eye viewpoints and the at least one of the plurality of right eye viewpoints.
