Abstract

The present application discloses a display apparatus including an image display portion for displaying an image, the image display portion emitting display light along a light propagating direction; and a light modulator assembly having a first light modulator and a second light modulator arranged in series along the light propagating direction. The second light modulator has at least a reflective optical state. The first light modulator is switchable between the reflective optical state and a transmissive optical state and is on a side of the second light modulator proximal to the image display portion. A total number of light modulators including the second light modulator and any light modulator on a side of the second light modulator proximal to the image display portion is N, N is an integer≥2.
