Embodiment Construction

[0040] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention and are not intended to limit the protection scope of the present invention.

[0041] Such as figure 1 As shown, the human eye 1 is approximately spherical, and the tissues with optical imaging functions are the cornea 102 and the lens 103 . The retina 104, located at the back of the eye, is the first stop for the transmission of neural information that forms vision. The cone cells on the retina are the main photoreceptor neurons and are directly opposite the end point of the visual axis. Such as figure 2 As shown, the distribution of cone cells is extremely uneven, the most dense in the fovea 105, and a small amount of distribution in other parts of the retina. Therefore, the central fovea is the area with the sharpest vision, and its diameter is about 1 to 3 mm. The fie...

Abstract

The present invention provides a head-mounted display device comprising a display screen which is a monochromatic or multichromatic organic light-emitting display screen having good light transmittance and through which a real scene can be seen in a non-lit or lit state, and an image conversion optical device that is used for converting an image generated by the display screen to the human eye visible distance and comprises one or more layers of microlens arrays; and one microlens of each microlens array corresponds to one or more pixels in the display screen. The image production system is avirtual-real fusion device, and the light weight of a head-mounted display scheme can be realized; in the 3D display scheme of the device, the nanostructures of the left and right light field lenses are symmetrical in a distributed manner, and a virtual scene generated between the left and right light field lenses has parallax, so that a binocular parallax effect is formed, and the observation habit of human eyes is met; the device has the advantages of few device units, simple structure and low manufacturing cost.

Description

technical field [0001] The invention belongs to the field of virtual display and enhanced display, and more specifically relates to a helmet-mounted 3D display device integrating image generation and visible lenses. Background technique [0002] Augmented reality (AR) technology is a new technology that "seamlessly" integrates real world information and virtual world information. Sound, taste, touch, etc.), through computer and other science and technology, simulate and then superimpose, apply virtual information to the real world, and be perceived by human senses, so as to achieve a sensory experience beyond reality. The real environment and virtual objects are superimposed on the same screen or space in real time. One of the characteristics of the AR system: adding and positioning virtual objects in a three-dimensional scale space is a difficult point in display technology. [0003] Most of the existing display methods use the combination of image generation system and v...
