Abstract: The present invention provides a near-eye display device, which is disposed in front of the eyes of a user and comprises: a single perspective image-overlapping component; two amplifying optics module that are a first amplifying optics module and a second amplifying optics module, an angle is between each of the first amplifying optics module and the second amplifying optics module and each of the eyes of the user, the two eyes includes a first eye and a second eye; two micro display devices that are a first micro display device and a second micro display device, an angle is between each of the first micro display device and the second micro display device and each of the first eye and the second eye, the first amplifying optics module is between the first micro display device and the perspective image-overlapping component, the second amplifying optics module is between the second micro display device and the perspective image-overlapping component; two switchable polarization films that are a first switchable polarization film and a second switchable polarization film, an angle is between each of the first switchable polarization film and the second switchable polarization film and each of the first eye and the second eye, the first switchable polarization film is between the first micro display device and the first eye, the second switchable polarization film is between the second micro display device and the second eye, a first imagined connecting line of the first amplifying optics module and the first micro display device connects with a second imagined connecting line of the first switchable polarization film and the first micro display device at the first micro display device, and a first angle is between the first imagined connecting line and the second imagined connecting line, a third imagined connecting line of the second amplifying optics module and the second micro display device connects with a fourth imagined connecting line of the second switchable polarization film and the second micro display device at the second micro display device, and a second angle is between the third imagined connecting line and the fourth imagined connecting line; wherein the first micro display device and the second micro display device emit a first polarization image line and a second polarization image line respectively, the first polarization image line has a first polarity, the second polarization image line has a second polarity, or the direction of the round first polarization image line is opposite to the direction of the round second polarization image line, the first polarization image line and the second polarization image line thus go through the first amplifying optics module and the second amplifying optics module and to the perspective image-overlapping component, the perspective image-overlapping component may reflects part of the first polarization image line and the second polarization image line to the first switchable polarization film and the second switchable polarization film respectively, the first switchable polarization film may let the first polarity be through, and the second switchable polarization film may let the second polarity be through, hence the first polarization image line and the second polarization image line reach the first eye and the second eye respectively.
