Abstract

The invention discloses a VR optical display module and display equipment. An image to be displayed is segmented into M sub-images through an image segmentation unit, the M sub-images are modulated and emitted at the same time through one or more image generation sub-units included in the image generation unit; wherein a mixed light beam containing a to-be-displayed image is formed after collimation of the collimation optical system, the mixed light beam is coupled into the waveguide module, the waveguide module is provided with multiple layers of coupling-in units and coupling-out units, andeach layer of coupling-in unit is configured to be coupled into a light beam of a sub-image; emergent images obtained after the to-be-displayed image mixed light beams are coupled out through the coupling-out units of the corresponding waveguide modules are spliced into a to-be-displayed image. Therefore, an image with depth can be presented through focusing of the zoom unit on the light-emittingpath of the waveguide module, Meanwhile, the shading unit shields other light rays except the mixed light beam of the image to be displayed from being emitted into the waveguide module. 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 invention relates to the field of display technology, in particular to a VR 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] At present, common near-eye display systems used in the VR field such as figure 1 As shown, it includes: a display screen 1, an optical magnification system 2 (lens group). Wherein, the image beam emitted by the display screen 1 enters the human eye through the optical amplification system 2, and...
