The invention discloses a single-image source binocular near-to-eye display device, which comprises a lens assembly, a first semi-transmitting and semi-reflecting plane mirror, a first plane mirror, a second plane mirror, a second semi-transmitting and semi-reflecting plane mirror, a first concave mirror and a first shutter; after passing through the lens assembly, a light ray is reflected to the first plane mirror through the first semi-transmitting and semi-reflecting plane mirror, reflected to the second plane mirror through the first plane mirror, and reflected to the second semi-transmitting and semi-reflecting plane mirror through the second plane mirror; after passing through the second semi-transmitting and semi-reflecting plane mirror, the light ray arrives the first concave mirror, is reflected to the second semi-transmitting and semi-reflecting plane mirror through the first concave mirror, and then, is reflected to the first shutter through the second semi-transmitting and semi-reflecting plane mirror; the single-image source binocular near-to-eye display device also comprises a third plane mirror, a third semi-transmitting and semi-reflecting plane mirror, a second concave mirror and a second shutter.
Description
technical field [0001] The invention relates to the technical field of image display, in particular to a single image source binocular near-eye display device. Background technique [0002] Near-eye display devices are also called head-mounted displays, and are used in military, scientific research, education, training, commercial exhibitions, medical treatment, entertainment and other fields. With the rapid development of virtual reality technology and augmented virtual reality technology, the demand for near-eye display devices is getting higher and higher. The near-eye display device should be worn on the head for a long time, and should be easy to wear and carry. Therefore, the requirements for miniaturization, portability and high performance of display devices are becoming more and more prominent. The shutter-type binocular near-eye display device based on timing, its display screen displays the left and right images in time-sharing, and controls the liquid crystal s...
