Problems solved by technology

When the viewer moves back and forth, the viewing angle changes, and even when the viewer moves to a distance within 800mm, the normal 3D display will not be seen
[0005] To sum up, with the prior art polarized 3D display technology, viewers can only see better display effects within a specific viewing distance and range.

Abstract

The embodiment of the invention provides a 3D display device and display method and a 3D display system. The 3D display device and display method and 3D display system achieve the situation that a viewer can always achieve an optimal viewing effect when moves back and forth in a large range. The 3D display device comprises a display panel, a phase delay unit, a sensing unit and an adjustment unit.The phase delay unit is located on a display side of the display panel and comprises a plurality of light polarization units, and the polarization direction of light emitted by every adjacent two light polarization units is perpendicular. The sensing unit is used for acquiring the viewing distance when the viewer views in real time. The adjustment unit is electrically connected with the sensing unit and the phase delay unit and is used for determining the width of the light polarization units corresponding to the viewing distance fed back in real time according to the viewing distance fed back by the sensing unit in real time and adjusting the width of the light polarization units to the determined width corresponding to the viewing distance fed back in real time.

Description

technical field [0001] The present invention relates to the technical field of 3D display, in particular to a 3D display device, a display method, and a 3D display system. Background technique [0002] Polarized 3D display technology, as a mature 3D technology, still has special applications in some places and fields, especially the current medical 3D display industry. [0003] For the conventional design of polarized 3D display technology in the prior art, the viewer can only obtain a better display effect at an optimal viewing distance. When the viewer moves back and forth, the crosstalk increases, the viewing angle becomes smaller, and the viewing effect will be reduced. [0004] The optical path diagram of the viewing area of ​​the prior art polarized 3D display technology changing with the viewing distance is as follows figure 1 shown, from figure 1 As can be seen in the figure, the best viewing distance for the viewer is 1200 millimeters (mm), and the minimum viewing...
