Abstract

The invention provides an image display method, near-to-eye display equipment and device, and relates to the technical field of optics. The image display method comprises the steps that a first FOV corresponding to each optical waveguide lens in multiple optical waveguide lenses of the near-to-eye display equipment is determined, and a second FOV of the near-to-eye display equipment is composed of first FOVs of the multiple optical waveguide lenses; for each optical waveguide lens, a grating parameter of a grating assembly of the optical waveguide lens is determined according to the first FOV; when an image source is displayed, incident light corresponding to the image source is diffracted according to the grating parameters, a plurality of first images are obtained, and the field angle of the image source is a second FOV; and the plurality of first images are spliced to obtain the second image corresponding to the image source, so that the plurality of first FOVs have no overlapped part by optimizing the grating parameters, the second image is ensured to have no ghosting, the uniformity of the second image is improved, and the eye movement range of the near-eye display equipment is expanded.

Description

technical field [0001] The present disclosure relates to the field of optical technology, and in particular to an image display method, near-eye display device and device. Background technique [0002] With the development of optical technology, projection display technology is becoming more and more mature, which promotes the emergence of near-eye display devices. A near-eye display device can present a virtual image within the viewing range of the user. The near-eye display device mainly includes an image source and a display module, wherein the image source is used to project the image source onto the display module. The display module is used to display the image corresponding to the image source projected by the image source. [0003] In order for the user to observe a larger range of the image source, it is necessary to ensure that the FOV (Field of view, field of view) of the near-eye display device is large enough. In order to meet the FOV requirements of near-eye...
