NEAR-EYE DISPLAY DEVICE AND NEAR-EYE DISPLAY SYSTEM

摘要

A near-eye display device (1) and a near-eye display system. An excited light source structure (04) provides an excited light to a first waveguide structure (01). A light-emission coupling grating structure (03) corresponding to the first waveguide structure (01) receiving the excited light can also be illuminated by the excited light received by the first waveguide structure (01) to be excited to output a light of a pixel color corresponding to the first waveguide structure (01), that is, the light-emission coupling grating structure (03) corresponding to the first waveguide structure (01) receiving the excited light can not only export a light of a corresponding pixel color emitted by a projection display, but can also be excited by the excited light emitted by the excited light source structure (04) and to output the light of the pixel color corresponding to the first waveguide structure (01), thus increasing the brightness of a light emitted by the near-eye display device (1).
