Abstract

The invention provides a near-to-eye display device which comprises a shell, a main support, a first lens, a second lens, a first support, a second support, a focal length adjusting mechanism, an interpupillary distance adjusting mechanism and a view field adjusting mechanism. The first support and the second support are movably installed in the main support, the first lens and the second lens are electrically connected with the display screen, the first lens is connected to the first support, the second lens is connected to the second support, and the focal length adjusting mechanism is used for adjusting the focal lengths of the first lens and the second lens. The interpupillary distance adjusting mechanism is used for adjusting the distance between the first lens and the second lens, and the field-of-view adjusting mechanism is used for adjusting the opening and closing angles of the first lens and the second lens. According to the invention, aiming at different observation targets, the pupil distance, the focal length and the overlapping view field are adjustable, and the dizziness of the equipment in the use process is eliminated as much as possible.

Description

technical field [0001] The present application belongs to the field of near-eye display equipment, and more particularly, to a near-eye display device. Background technique [0002] At present, the near-eye display system usually consists of a micro-projection and a waveguide display, and the projected image light is transmitted to the human eye through the display to realize near-eye display. For different users, the product structure is designed with a manual interpupillary distance adjustment mechanism. When in use, the interpupillary distance can be adjusted according to the actual observation needs of each person, thereby improving the image effect seen by the human eye. [0003] In the prior art, when observing different personnel wearing equipment, the distance between the eyepieces is manually adjusted to meet the best matching observation effect of the human eye, and the discomfort of the human eye to the image can be alleviated as much as possible, but the two came...
