Problems solved by technology

The existing viewing distance adjustment assembly can only adjust the viewing distance of the left lens barrel assembly and the right lens barrel assembly synchronously. The viewing distance will lead to different clarity of the image seen by the left eye and right eye when the user watches the image through the optical module, which will affect the visual experience

Abstract

The invention discloses an optical module group and a head-mounted display device. The optical module group comprises a module group housing and a left lens barrel assembly and a right lens barrel assembly arranged in the module group housing. A left display screen is arranged behind the left lens barrel assembly and a right display screen is arranged behind the right lens barrel assembly. The optical module group also comprises a left visibility range adjustment mechanism arranged on the left lens barrel assembly for adjusting the distance between the left display screen and the left lens barrel assembly and a right visibility range adjustment mechanism arranged on the right lens barrel assembly for adjusting the distance between the right display screen and the right lens barrel assembly. According to the optical module provided by the invention, the left lens barrel assembly and the right lens barrel assembly are respectively provided with the left display screen and the right display screen, and the left and right visibility range adjusting mechanisms respectively adjust the visibility ranges of the left lens barrel assembly and the right lens barrel assembly to allow a user to see a sharper image.

Description

technical field [0001] The invention relates to the field of display devices, in particular to an optical module and a head-mounted display device. Background technique [0002] With the development of technology and people's increasing demand for multimedia video, commonly used multimedia playback devices need to be used with an external LED or LCD display, because the pixels and size of the image displayed on the external display are limited by the size of the display and Visual effects cannot meet people's needs, and head-mounted displays have emerged as the times require. A head-mounted display (HMD for short) is an optical product for stereoscopic vision display. It is a signal with a three-dimensional effect of binocular parallax, which is sequentially transmitted through the display elements and optical lenses arranged in front of the eyes. It is sent to both eyes to produce a three-dimensional and large-size image. The head-mounted display device is usually applied...
