Abstract

The invention relates to the field of near-to-eye display technologies, in particular to a near-to-eye display device. The near-to-eye display device comprises a left-eye optical path system and a right-eye optical path system, wherein each of the left-eye optical path system and the right-eye optical path system comprises a first optical path and a second optical path, light emitted by the display device enters a left eye and a right eye via the first optical paths separately, and ambient light enters the left eye and the right eye via the second optical paths separately; the initiating end of each second optical path is provided with a first detachable baffle plate, and a second detachable baffle plate is arranged between the left-eye optical path system and the right-eye optical path system. By arranging the first detachable baffle plates at the entering ends of the ambient light, switching of VR display and AR display is realized; by arranging the second detachable baffle plate between the left-eye optical path system and the right-eye optical path system, conversion of 3D image display and 2D image display is realized; and the use performance of the near-to-eye display device is significantly improved, the user experience is enhanced, and the compatibility is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a near-eye display device. Background technique [0002] Near-eye display, also known as helmet display, is a way of using optical lenses to realize virtual display of large-screen images. The near-eye display system generally includes a micro-display device, a system optical path, and an eyepiece. Its working principle is that the light emitted by the micro-display device is processed by the system optical path and then passes through the eyepiece to form a virtual image. Near-eye display is divided into monocular display and binocular display. Monocular display has only one micro-display device for monocular viewing; binocular display has two micro-display devices for binocular viewing. The binocular near-eye display system consists of left and right eyes It consists of two optical paths, and each optical path has a light emitted by a micro-display device and enters the eye t...
