Embodiment

[0065] The optical structure of projection unit 10 is as figure 1 As shown, it includes a display unit 11 , a converging device 12 , and a deflection aperture 13 . figure 1 The middle display unit 11 is an example of a self-luminous display device, the converging device 12 is an example of a lens, and the deflection aperture 13 is an example of a reflective surface. The components of the same projection unit 10 correspond to each other. Wherein, the display unit 11 is composed of pixel arrangement, as shown in the figure p i1 ,p i2 ,p i3 ,p i4 ,...p iM Each pixel includes sub-pixels for loading light information; the converging device 12 converges the light projected by the display unit 11, so that the light distribution after converging covers the deflection aperture 13; the deflection aperture 13 deflects the transmission path of the incident light through the converging device 12. The components of the same projection unit 10 correspond to each other. A plurality of ...

Abstract

The invention discloses a near-to-eye display module for relieving constraint of a fixed focusing surface. The near-to-eye display module comprises at least one projection module formed by combining a plurality of projection units, a supporting piece for supporting the projection units, and a control device. Wherein each projection unit comprises a display unit, a convergence device for converging the projection light of the display unit, and a deflection aperture for deflecting the transmission direction of the incident light through the convergence device. An observer wears the near-to-eye display modules in the two eyes respectively, in the near-to-eye display modules corresponding to all the eyes, all the projection units of the same projection module jointly project at least one complete image to the eyes, and three-dimensional display overcoming focusing-convergence conflicts is achieved based on a Maxwellian view or / and a monocular multi-view technical path. According to the near-to-eye display module, a small-size deflection aperture is adopted, divergence angles of light beams entering pupils of an observer are restrained, and the problem that a view field is limited by the size of the deflection aperture is solved through spatial splicing of projection information of a plurality of projection units.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional image display, and more specifically, relates to a near-eye display module that removes the constraint of a fixed focal plane. Background technique [0002] As a potential new-generation mobile terminal platform, VR / AR has extremely broad application prospects in all aspects. However, most of the existing VR / AR systems are based on traditional stereoscopic technology for the presentation of three-dimensional scenes. Through the corresponding eyepieces of the observer's binoculars, a corresponding two-dimensional image is projected to the observer's binoculars, and the binoculars are used to look at the corresponding The spatial intersection of depth triggers the observer's depth perception. During this process, each eye of the observer needs to focus on the corresponding display surface in order to clearly see the corresponding two-dimensional images, which leads to the inconsis...
