ABSTRACT:
The present invention provides a display apparatus, comprising: a light source; at least one spatial light modulator for modulating a luminous flux emitted from the light source; and controller for processing video image information, which is input, and controlling the light source and the spatial light modulator, wherein the controller controls the light source and the spatial light modulator so as to perform pulse emission of the light source during a period shorter than a period in which the spatial light modulator is controlled under a modulation state and also controls the light source so as to modulate the pulse emission during a period shorter than a period in which the spatial light modulator is controlled under a modulation state.
