Embodiment 1

[0038] Such as figure 1 As shown, the transmittance of the present embodiment is adjustable, the virtual reality imaging module 103 is a nearing display lens, which can be a prism reflection similar to Google Glass, or a waveguide similar to HOLOLENS. Or the use of the free surface mirror used in other products, its function is to projep the digital image to a few meters before the optical imaging, so that the human eye can be more comfortable. Prior to the virtual reality imaging module 103, there is a protective lens 102 for protecting the reflective lens, prior to the protective lens 102, with the light intensity damper 101, the light intensity transmittance of the light intensity damper 101 is T, wherein 0 <t <1, a natural light for different intensities can be superimposed on the protective lens 102 by selecting the light intensity damper 101 of different transmittance T. Optics from the natural scene from the human eye, it is necessary to pass the light power failure 101 and...

Embodiment 2

[0042] Such as figure 2As shown, the difference from the first example is that the transmittance of natural light is achieved by the superposition effect of the first optical polarizing plate 104 and the second optical polarizing plate 105. In the present embodiment, the first optical polarizing plate 104 has a first polarization direction, and the second optical polarizing plate 105 has a second polarization direction, wherein there is an angle A, 0 ° ≤a in the first polarization direction and the second polarization direction. ≤90 °, when A = 0 °, the superimposed transmittance T is highest, theoretically, the upper level can reach the level close to 1; when A = 90 °, the superimposed transmittance T is the lowest, theoretical It can achieve a level close to 0. Thus, by changing the angle A in the polarization direction of the first optical polarizing plate 104 and the second optical polarizing plate 105, the effect of adjusting the brightness of the natural light can be achieve...

Embodiment 3

[0046] Such as image 3 As shown, it is different from the second embodiment in that the second optical polarizing plate in Example 2 is split into two circular polarizing plates, that is, left eye optic polarizing plate 106 and right eye optic polarizing plate. 107. By rotating the left eye optic polarizing plate 106 and the right eye optic polarizing plate 107, the polarization direction thereof is enamed in the polarization direction of the first optical polarizing plate 104, thereby achieving the adjustment of the transmittance T. Since the rotation of the left eye optic polarizing plate 106 and the right eye optic polarizing plate 107 can be continuous, the adjustment of the transmittance T is continuous, and therefore, compared to the second example, whether in the adjustment effect, simpleness and cost This embodiment has a significant advantage. When most of the brightness of most of the use scenarios, left eye and right eye is consistent, the comfort of the human eye is op...

Abstract

The invention provides a transmittance-adjustable augmented reality display structure and a head-mounted display device, and the structure comprises: a virtual reality imaging module which is used for displaying a virtual image; a light transmittance adjusting module which is located in front of the virtual reality imaging module; and a light transmittance adjusting module is used for adjusting the brightness of natural light rays which penetrate through the light transmittance adjusting module. According to the augmented reality display structure with the adjustable transmittance, a user can adjust the transmittance of natural light entering human eyes in scenes with different light brightness, the brightness ratio of the natural light to a digital image is adjusted, and the augmented reality display effect is improved.

Description

Technical field [0001] The present invention relates to the field of virtual reality devices, and more particularly to an enhanced realistic display structure (including the enhanced real display structure), which includes a headset display device including the enhanced real display structure. Background technique [0002] Currently, existing enhanced realistic displays generally use free surface mirrors or waveguide lenses, project digital images to a few meters from the front of the person, and view it for people. The free surface mirror or waveguide lens is transparent, and the human eye can see both projected digital images, and can also see the realistic scenes in front, resulting in enhanced reality. The comparative representative product is Google Glass and Microsoft's Hololens. These two products are at mostly a lens that protects the protected lens, but does not do any attenuation for natural light. In the outdoor use, since the brightness of natural light is much higher...
