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

Abstract

The invention provides a three-dimensional display device and system and a three-dimensional display method and belongs to the technical field of display. The three-dimensional display device comprises a first display source, a first optical element, a second display source and a second optical element, wherein the first display source is used for providing a first eye picture; the first optical element is located on a light path of an emergent ray of the first display source and is capable of reflecting the emergent ray of the first display source to make the reflected ray reach a preset position point; the second display source is used for providing a second eye picture; and the second optical element is located on a light of an emergent ray of the second display source and is capable of reflecting the emergent ray of the second display source to make the reflected ray reach the preset position point, wherein a virtual image of the first eye picture seen at the preset position point overlaps with the virtual image of the second eye picture seen at the preset position point, the first eye picture is one of a left eye picture and a right eye picture and the second eye picture is the other one of the left eye picture and the right eye picture. According to the three-dimensional display device and system and the three-dimensional display method, the three-dimensional display effect can be better.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a stereoscopic display device, system and stereoscopic display method. Background technique [0002] The prior art proposes a stereoscopic display device capable of realizing stereoscopic display of information, such as figure 1 As shown, the existing stereoscopic display device includes a first combiner 20, a second combiner 420, and a light projector 30, wherein the light projector 30 includes: a first light projector 31, which generates the display light reaching the first combiner 20 part, and the second light projecting part 32, which generates a part of the display light reaching the second combiner 420, and the first combiner 40 and the second combiner 420 are configured so that their respective virtual images C1 and C2 overlap to generate a three-dimensional Show C. but if figure 1 As shown, the two images C1 and C2 share the same light projector 30, resulting...

Problems solved by technology

but if figure 1 As shown, the two images of C1 and C2 share a light projector 30, resulting in a small stereoscopic effect of the displayed image, and before C1 enters the human eye, it needs to pass through the second combiner 420, and the brightness is greatly attenuated, resulting in poor stereoscopic image quality
