Abstract

The invention discloses an AR optical display module and display equipment. An image to be displayed is segmented into M sub-images through an image segmentation unit, m sub-images are scanned and emitted at the same time through one or more scanning optical fibers of an optical fiber scanner in the optical fiber scanning module, a mixed light beam containing a to-be-displayed image is formed after collimation of the collimation optical system and coupled into the waveguide module, and each layer of coupling unit in the waveguide module is configured to be a light beam coupled into one sub-image; emergent images obtained after the to-be-displayed image mixed light beams are coupled out through the corresponding coupling-out units are spliced into a to-be-displayed image; focusing is carried out through a zoom unit on a light-emitting path of the waveguide module; Meanwhile, the light compensation unit arranged opposite to the variable-focus unit synchronously offsets the focal length of the variable-focus unit, so that external natural light beams entering the display module are prevented from being influenced by the variable-focus unit, and the effect of augmented reality displayis effectively improved. According to the invention, the problems of large view field, adjustable depth and miniaturization of the near-to-eye display module are solved by a brand-new thought.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an AR optical display module and a display device. Background technique [0002] With the development of society, augmented reality technology (English: Augmented Reality; abbreviation: AR) and virtual reality technology (English: Virtual Reality; abbreviation: VR) have been applied more and more. Augmented reality technology superimposes virtual information on the real world for users to watch, and virtual reality technology provides a complete virtual world for users to watch. Both are widely used in medicine, entertainment, education, industrial simulation and other fields. [0003] Such as figure 1 As shown, the existing near-eye display system applied in the AR field generally includes: an image source 1, an eyepiece system 2, an in-coupling grating 3, a waveguide 4, and an out-coupling grating 5; wherein, the light beam emitted by the image source 1 passes through...
