Problems solved by technology
[0004] Currently used VR / AR display devices, the focal length of the display screen is fixed. When the human eye observes the display screen, it focuses on the same image plane for a long time, which conflicts with the adjustment of the brain to the optic nerve. When the human eye continues to watch such a display screen for too long , there will be fatigue and dizziness, resulting in convergence conflicts

The invention provides a near-to-eye display device. The device comprises: a first display which is used for displaying a first image and enables the first image to enter a spectroscope through a first imaging lens; a second display used for displaying a second image and entering the spectroscope through the second imaging lens; a spectroscope used for transmitting the imaging light of the first imaging lens and reflecting the imaging light of the second imaging lens; a waveguide sheet positioned on a light emitting path of the spectroscope and used for receiving and conducting the emergent light of the spectroscope; and a light taking part arranged in the waveguide sheet and used for reflecting the imaging light conducted in the waveguide sheet to the position where the human eyes are located. Due to the fact that the image distances of the first imaging lens and the second imaging lens are different, the first image and the second image can display images on two image planes, when the image of one image plane is observed through adjustment of human eyes, the image of the other image plane is blurred and consistent with the feeling of watching actual scenery, and therefore convergence conflicts are eliminated.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular to a near-eye display device. Background technique [0002] Near-eye display is a current research hotspot, such as virtual reality display in the form of a helmet and augmented reality display in the form of smart glasses. Near-eye display can provide people with an unprecedented sense of interaction, and has important application value in many fields such as telemedicine, industrial design, education, military virtual training, and entertainment. [0003] Virtual reality (Virtual Reality, referred to as VR) technology presents a fully enclosed virtual environment, and augmented reality (Augmented Reality, referred to as AR) technology is an enhanced projection method that superimposes virtual scenes on the real environment. The display method has entered the public's field of vision and has begun to be widely used. [0004] Currently used VR / AR display devices, the foc...
