1. A display device, comprising:
a light source system, configured to emit a plurality of primary color light;
a light splitting element, configured to split at least one of the plurality of the primary color light into first light and second light, wherein a ratio of luminous flux of the first light to the at least one of the plurality of primary color light is defined as a first light output ratio, and a ratio of luminous flux of the second light to the at least one of the plurality of primary color light is defined as a second light output ratio;
a first light modulator, located in a light path of the first light to modulate the first light and output a first luminous flux unit based on the first light and a minimum modulation duration of the first light modulator; and
a second light modulator, located in a light path of the second light to modulate the second light to output the second light along a same light path as the first light after being modulated, and output a second luminous flux unit based on the second light and a minimum modulation duration of the second light modulator;
wherein a second luminous flux set is obtained by performing a preset processing on a first luminous flux set composed of luminous fluxes output by a combination path in which light output by the first light modulator and light output by the second light modulator are combined; and
the second luminous flux set corresponds to a luminous flux set at a high display bit depth of the display device.
