Abstract

The present disclosure relates to a display device and a display method thereof. The display device includes: a plurality of sub-pixels each including a light emitting element and a liquid crystal spatial light modulator, wherein the liquid crystal spatial light modulator is located on a light emission side of the light emitting element, and a phase of light emitted by the light emitting element is modulatable after passing through the liquid crystal spatial light modulator; a first control circuit configured to control a light emission intensity and chromaticity of the light emitting element; and a second control circuit configured to control deflection of liquid crystal in the liquid crystal spatial light modulator so as to modulate the phase.
