Abstract

The invention discloses a waveguide display device, which relates to the technical field of optics. The waveguide display device comprises an image source, a relay optical system, an input coupler, a waveguide and an output coupler, wherein the image source is used for displaying an image; the relay optical system is used for emitting the image displayed by the image source to the input coupler; the input coupler is used for coupling emergent light of the relay optical system to the waveguide; and the output coupler is used for coupling out light propagated in the waveguide. The optical device can use the small-sized image source, and the design difficulty and the complexity degree of the relay optical system can be reduced.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a waveguide display device. Background technique [0002] With the development of science and technology, augmented reality display devices are receiving more and more attention. In order to make the augmented reality display device adaptable to different users and ensure that there will be no image loss during strenuous exercise, the augmented reality display device needs to have a larger exit pupil diameter, and the display device is also required to be miniaturized and lightweight. [0003] However, in the prior art, the purpose of large exit pupil and large field of view of the augmented reality display is generally achieved by increasing the volume of the image source and the diameter of the relay optical system, etc., which greatly increases the volume and weight of the display device . In addition, in order to obtain a better display effect, the lenses of the relay syst...
