Embodiment 1

[0025] A near-eye display device such as figure 1 and figure 2 As shown, it includes: a set of image display screen unit 8 for displaying image 9, a set of optical lens set 6 for correcting various optical image points of optical imaging, a set of optical length extension and optical path A set of optical prism group devices 5 for turning, a set of prism beam splitting surface devices 4 for image light splitting and light path turning, and a set of optical reflection devices 3 for image optical reflection and light field compression.

[0026] Further, the image display screen unit 8 may be a common display screen in the market, which is used to display the image to be displayed, which belongs to the prior art and will not be repeated here.

[0027] Further, the optical lens group device 6 is located below the image display screen unit 8, and the optical lens group device 6 is composed of one or more optical elements. The optical elements can be lenses, and the lenses can be ...

Embodiment 2

[0032] An imaging method of a near-eye display device, comprising the following steps:

[0033] Step 1, the image display screen unit 8 displays the required image 9, and the image light enters the optical lens group device 6 to correct the optical image point of the optical imaging to form a corrected image light 10;

[0034] Step 2: After the corrected image light 10 enters the optical prism assembly device 5, the optical path is increased to form the extended image light 11;

[0035] Step 3: After the extended-range image light 11 is internally or externally reflected by the optical reflection device 3, it becomes a parallel light of an image point suitable for human eyes to observe, and the parallel light enters the optical prism group again. device 5;

[0036] Step 4. When the range-extended image light 11 reaches the prism beam splitter device 4, a part of the light rays are reflected by the prism beam splitter device 4 and then pass through the optical prism group devi...

specific Embodiment

[0039] The following is a specific embodiment of the present invention. In this embodiment, the imaging method of the near-eye display device includes the following steps:

[0040] Step 1. Display the image 9 to be displayed on the image display screen unit 8, an optical lens group device 6 is arranged below the image display screen unit 8, and the image light 7 is emitted from the image display screen unit 8, and passes through one or more into the optical lens group device 6 composed of one or more optical elements and then enter the optical prism group device 5 composed of one or more optical elements;

[0041]In step 2, a prism beam splitter device 4 composed of one or more optical elements is arranged inside the optical prism group device 5 , an optical reflection device 3 is arranged below the optical prism group device 5 , and the image light 7 is inside the optical reflection device 3 . Under the action of reflection or external reflection, it becomes light that can be...
