All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment provides an augmented reality display device, which includes a waveguide and at least two optical machines, where the waveguide includes an out-coupling area and at least two in-coupling areas, where the in-coupling area is configured to enable light emitted by the optical machines corresponding to the out-coupling area to enter the waveguide, the out-coupling area is configured to enable light from the in-coupling area to be at least partially coupled outside the waveguide, and a field angle of the light emitted by each optical machine may be combined into a preset field angle, so that the field angle of the light coupled outside the waveguide by the out-coupling area reaches the preset field angle.
The waveguide is a waveguide structure capable of guiding light to propagate. The optical machine corresponds to the coupling-in area of the waveguide, and the coupling-in area enables light emitted by the optical machine corresponding to the coupling-in area to enter the waveguide. When the light propagating along the waveguide reaches the outcoupling region, at least a part of the light is emitted out of the waveguide through the outcoupling region. The light enters human eyes, so that the human eyes can see the image.
Emergent light rays of the optical machines enter the waveguide and are coupled out of the waveguide through the coupling-out area, and the light rays correspondingly coupled out of the optical machines are converged to form light rays output by the augmented reality display device. The field angles of the emergent rays of the ray machines can be combined into a preset field angle, so that the field angle of the rays coupled out of the waveguide by the coupling-out region can reach the preset field angle. Therefore, the field angle can be reduced for each optical machine, and the image brightness can be prevented from being reduced. Therefore, the augmented reality display device of the embodiment can meet the requirement of the angle of view of the light rays of the output image, and can avoid the reduction of the image brightness.

Preferably, the incident angle of the outgoing light of each optical machine incident on the coupling-in region corresponding to the optical machine is the same, so that the light corresponding to each optical machine enters the waveguide and propagates in the same manner in the waveguide, for example, the angle at which the light corresponding to each optical machine couples into the waveguide is the same, and the angle at which total reflection propagation is performed in the waveguide is the same. Accordingly, the angle of view of the light coupled out of the waveguide by the coupling-out region can be brought to the predetermined angle of view.
In this embodiment, the number of the coupling-in regions and the number of the optical machines included in the waveguide are not limited, and in practical application, the number of the coupling-in regions and the number of the optical machines may be set according to requirements for an output image of the display device, such as a field angle and brightness of the output image, power consumption of the device, and a system structure. In this embodiment, the size of the angle of view of the emergent light of each optical machine is not limited as long as the angle of view of the emergent light of each optical machine can be combined into a preset angle of view.
Optionally, as an embodiment, the at least two optical machines may include a first optical machine and a second optical machine, where a horizontal/vertical field angle of light emitted from the first optical machine is- α 1 degree to 0 degree, and a horizontal/vertical field angle of light emitted from the second optical machine is 0 degree to α 2 degree. Then, the first ray machine emergent ray and the second ray machine emergent ray can be combined to form a horizontal/vertical field angle of-alpha 1-alpha 2 degrees. Wherein α 1 and α 2 are positive numbers, respectively. Defining the deviation of the emergent ray of the optical machine to the left side of the optical axis of the optical machine, wherein the angle of the emergent ray is negative; the emergent ray of the optical machine is deviated to the right side of the optical axis of the optical machine, and the angle of the emergent ray is positive.
