Benefits of technology

This patented design allows for better control over how much space on an eyewear screen can be displayed by providing smaller lenses with greater refractive power near their center compared to other parts around them. By doing this, we aim to make our eyesight look smoother even if they're worn constantly or moving about too quickly during use.

Problems solved by technology

This patented problem addressed by this patents relates to improving on conventional designs for achieving larger angles at both ends (the eyes) while also reducing their sizes or weights without compromising image clarity.

example 2

[0095] Based on the content of the above-mentioned embodiments, the second example of the head-mounted display device provided by the embodiment of the present invention is as follows: Figure 5As shown, any off-axis optical system included in the head-mounted display device includes a free-form surface lens S4, a lens group and an image display 1, and the internal space of the head-mounted display device also includes people who form an optical path with the off-axis optical system. Eye position, the position of the human eye is represented by the exit pupil diameter 2. Wherein, the lens group includes 4 aspheric lenses, and the 4 aspheric lenses are positive lens S5, convex lens S1, cemented lens S2 and convex lens S3 in sequence along the direction toward the free-form surface lens S4.

[0096] In this lens group, there is a convex lens at the front and back of the cemented lens S2, and the combination of the convex lens, the concave lens, and the convex lens can effectivel...

Abstract

The invention discloses a head-mounted display device, comprising: a casing, an off-axis optical system arranged in the casing, the off-axis optical system includes a free-form surface lens, a lens group, and an image display; the image light emitted by the image display is sequentially After being refracted by the lens group and reflected by the free-form surface lens, it enters the eyes of the wearer of the head-mounted display device, so that the wearer can watch the image; the lens group includes N aspheric lenses, and any adjacent two Aspheric lenses are set off-axis, where N is a positive integer greater than 2 and less than 6, and N aspheric lenses also meet at least one of the following conditions: the off-axis angle of any two adjacent aspheric lenses is not greater than 30° °; The deviation distance between any two adjacent aspheric lenses is not greater than 30mm. The overall design of the above-mentioned off-axis optical system is beneficial for the head-mounted display device to have the advantages of light weight, small volume and large viewing angle.
