Lens for head-mounted display device and head-mounted display device

Abstract

The invention discloses a lens for a head-mounted display device and the head-mounted display device. The lens for the head-mounted display device comprises a human eye side convex lens and a far human eye side convex lens, wherein the human eye side convex lens and the far human eye side convex lens are arranged abreast. A first aspheric surface protruding outwards is arranged on one surface of the human eye side convex lens, and a second aspheric surface concaved inwards is arranged on the other surface of the human eye side convex lens. A third aspheric surface protruding outwards is arranged on one surface of the far human eye side convex lens, and a fourth aspheric surface concaved inwards is arranged on the other surface of the far human eye side concave les. The second aspheric surface is opposite to the third aspheric surface. Light rays emitted by a displayer in the head-mounted display device pass through the far human eye side convex lens and the human eye side convex lens in sequence and enter human eyes to form an image, the intersection points of reverse extension lines of the light rays entering the human eyes form the image seen by the human eyes, the anti-shaking performance and the field range are improved effectively, and the field angle is made to reach 90 degrees. Meanwhile, due to the fact that the lens for the head mounted display device is formed by assembling two aspheric surface convex lenses, the overall structure is simple, and the processing difficulty of the convex lenses is small.

Description

technical field [0001] The present invention relates to a visual device, in particular to a lens for a head-mounted display device and the head-mounted display device. Background technique [0002] With the advancement of the technology industry, 3D display technology can simulate real scenes. As an emerging technology, the head-mounted display device has a good development prospect in the entertainment field. The head-mounted display device uses 3D display technology to bring the two-dimensional plane picture to the player in a more three-dimensional image, creating an immersive experience. sense of reality. The lens in the head-mounted display device is one of the important components. The lens mainly realizes the display of 3D images. The existing lens usually adopts the lens form of 3D movie mode. Its complex structure is difficult to process, and the field of view is small. Shake performance is poor. Contents of the invention [0003] The technical problem to be s...
