Abstract

The invention discloses an augmented reality display device, which is characterized in that a waveguide comprises a coupling-out area and at least two coupling-in areas, the coupling-in areas are used for enabling light rays emitted by ray machines corresponding to the coupling-in areas to enter the waveguide, and the coupling-out areas are used for enabling at least part of the light rays from the coupling-in areas to be coupled out of the waveguide; wherein the field angle of the emergent light of each light machine can be combined into a preset field angle, so that the field angle of the light coupled out of the waveguide by the coupling-out area reaches the preset field angle, and therefore, the field angle of each light machine can be reduced, and the reduction of the image brightness can be avoided. According to the augmented reality display device, the field angle of the output image light can meet the requirement, and the image brightness can be prevented from being reduced.

Description

technical field [0001] The invention relates to the technical field of virtual reality display, in particular to an augmented reality display device. Background technique [0002] Currently, the development trend of augmented reality display devices includes full-coverage field of view, high brightness, and full-color display. The full-coverage field of view of an augmented reality display device means that the light projected by the display device can cover the visual field of view of the human eye. The visual field of view of the human eye is about 40°*80°, that is, the vertical field of view The range is ±20°, and the horizontal field of view range is ±40°. [0003] In the prior art, in order to realize that the augmented reality display device can cover such a large field of view range, it is necessary to set the optical machine used by the display device to have a larger field of view angle, but this will lead to a decrease in image brightness, which cannot meet the ap...
