Abstract: A near-eye display device is disclosed that includes a pixel display configured to display multiple groups of pixels, in each frame of image, that are output by scanning. The device includes multiple semi-reflectors, where each semi-reflector is in a one-to-one correspondence with each group of pixels displayed by the pixel display unit. Each semi-reflector includes multiple inner platings that are disposed at different reflection angles. Each of the inner platings is in a one-to-one correspondence with each pixel subunits that is in a group of pixels corresponding to a semi-reflector in which the inner plating is located. Each semi-reflector is configured to be activated when the group of pixels corresponding to the semi-reflector is reflected, and reflect each pixel subunit which is in a one-to-one correspondence with each of the inner platings to a direction of an eyeball center by using all the inner platings included in the semi-reflector.
