Abstract
Disclosed are a near-eye display device and a near-eye display system. The excitation light source structure provides excitation light to the first waveguide structure, and the outgoing coupling grating structure corresponding to the first waveguide structure receiving the excitation light may be further irradiated by the excitation light, and be excited and output the light with a pixel color corresponding to the first waveguide structure. That is, the outgoing coupling grating structure corresponding to the first waveguide structure receiving the excitation light can derive the light with the corresponding pixel color emitted by the projection-based display, and be excited by the excitation light emitted by the excitation light source structure to output light with a pixel color corresponding to the first waveguide structure.
