Problems solved by technology

If the optical systems of the left eye and the right eye are inconsistent, it will cause differences in the imaging effects of the left eye and the right eye. The focusing power and direction of the left and right eyeballs are inconsistent, which will cause visual fatigue and even affect vision. The system uses two Microdisplay device, high cost

Embodiment 1

[0027] Such as figure 1 As shown, the binocular near-eye display system in this example includes a microdisplay device 1 , a reflector 2 , a reflector 3 , an X-shaped polarization beam splitting reflective plane mirror 4 , a left-eye eyepiece 5 and a right-eye eyepiece 6 . Reflector 3 and left-eye eyepiece 5 constitute a left-eye eyepiece system, and reflector 2 and right-eye eyepiece 6 constitute a right-eye eyepiece system.

[0028] Its working principle is: the light emitted by the micro-display device 1 is split by the X-shaped polarized spectroscopic reflective plane mirror 4, and then reflected by the mirror 2 and the mirror 3 to the left eyepiece 5 and the right eyepiece 6, and then enters the left eye respectively. and right eye.

[0029] The microdisplay device in this example adopts a non-polarized light microdisplay device, and the light emitted is natural light. The light splitting system adopts an X-shaped polarized beam splitting reflector, and what the reflecto...

Embodiment 2

[0031] Such as figure 2 As shown, the binocular near-eye display system in this example includes a microdisplay device 1 , a polarization splitting reflective prism 2 , a polarization splitting reflective prism 3 , a left-eye eyepiece 5 and a right-eye eyepiece 6 . Here, the polarization beam-splitting reflective prism 2 and the polarization beam-splitting reflector 3 are combined into an X-shaped polarization beam-splitting reflector 4 to form a beam-splitting system. 2 and the right-eye eyepiece 6 constitute the right-eye eyepiece system.

[0032] Its working principle is: the light emitted by the micro-display device 1 passes through the polarization beam-splitting reflective prisms 2 and 3, and then reflects to the left-eye eyepiece 5 and right-eye eyepiece 6, and then enters the left eye and the right eye respectively.

[0033] The micro-display device in this example uses a non-polarized light micro-display device, the light emitted is natural light, and the light-spli...

Embodiment 3

[0035] Such as image 3 As shown, the binocular near-eye display system in this example includes a microdisplay device 1 , a curved reflector 2 , a curved reflector 3 , and an X-shaped polarization beam splitting reflective plane mirror 4 .

[0036] Its working principle is: the light emitted by the micro-display device 1 is split by the X-shaped polarized beam-splitting mirror 4, then reflected by the curved mirror 2 and the curved mirror 3, and then enters the entrance pupils of the left eye and the right eye. Here the curved mirrors 2 and 3 function as eyepieces, forming a left-eye eyepiece system and a right-eye eyepiece system.

[0037] The microdisplay device in this example adopts a non-polarized light microdisplay device, the light emitted is natural light, and the light splitting system adopts an X-shaped polarized light splitting reflective plane mirror.

Abstract

The invention relates to an optical display, in particular to a binocular NTE display system. The invention discloses a binocular NTE display system which can realize binocular watching by only one microdisplay. The invention adopts the technical proposal that: the binocular NTE display system comprises the microdisplay, an optical splitting system, a left eye ocular system and a right eye ocular system; and the optical splitting system splits the light emitted by the microdisplay into two paths to respectively enter in the left eye ocular system and the right eye ocular system. The binocular NTE display system has a simple structure, reduces the cost, solves the problem that the left eye and the right eye of the binocular NTE display system in the prior art are not easy to align for imaging, and is suitable for various NTE display.

Description

technical field [0001] The invention relates to an optical display, in particular to a binocular near-eye display system. Background technique [0002] Near-eye display, also known as helmet display, is a way of using optical lenses to realize virtual display of large-screen images. A near-eye display system generally includes a microdisplay device, a system optical path, and an eyepiece. Its working principle is: after the light emitted by the micro-display device is processed by the optical path of the system, it forms a virtual image through the eyepiece. Near-eye display is divided into monocular display and binocular display. Monocular display has only one micro-display device for single-eye viewing; binocular display has two micro-display devices for binocular viewing. The binocular near-eye display system in the prior art is composed of two optical paths of the left eye and the right eye, and each optical path has a light emitted by a micro-display device entering t...
