However, most 3D stereoscopic display devices currently use a single image source, and the display image is in left and right format, so that the image lateral resolution of the monocular field of view is reduced by half, even though the limitation of the aperture stop of the conventional display system on the field angle is overcome, the binocular single-screen system increases the field of view through the amplification of the optical amplification system, and the image resolution is still reduced because the single-screen image source needs to process the video format to adapt to both eyes during the application process. Meanwhile, the visual magnification of the optical system is limited by the limit resolution of human eyes. In addition, two micro display devices are used as image sources of left and right eyes in a binocular 3D stereoscopic display device, and the resolution of the micro display devices cannot be greatly improved due to the limitation of the prior art. For 3D stereoscopic display equipment with light weight and small volume, due to the fact that the optical structure is simple, the number of optical elements is small, the diameter and the thickness of a magnifier system limit the view field, and the 3D stereoscopic image display effect and the immersion feeling of a user are greatly influenced. Therefore, under the condition of not changing the resolution of an image source, how to effectively increase the field of view and reduce aberration becomes an important technical problem to be solved urgently.
