Zusammenfassung:The present invention discloses a near-eye display based on a holographic waveguide, comprising: an optical waveguide and a group consisting of an array light source, an in-coupling optical element, a reflective spatial light modulator, and an out-coupling optical element which are disposed on both sides of the optical waveguide. The array light source and the in-coupling optical element are located on different sides of the optical waveguide. A human eye viewpoint position is located at the opposite side of the out-coupling optical element. The light emitted by the array light source is reflected by the in-coupling optical element, then irradiates the reflective spatial light modulator to be modulated by the reflective spatial light modulator, and then is reflected to the out-coupling optical element. The modulated light is output from the optical waveguide into human eyes by the out-coupling optical element. The reflective spatial light modulator and the array light source have synchronous driving signals.
