1. An air ionization display device, comprising:
a pulse-light-source module configured to generate a plurality of synchronous pulse light beams; and
a light field control module, the plurality of pulse light beams being projected to the light field control module and the light field control module being configured to adjust and converge the plurality of pulse light beams and ionize air in a display area to form a holographic real image,
wherein the pulse-light-source module comprises:
a plurality of pulse light sources configured to generate the plurality of pulse light beams, respectively; and
a first beam combiner, the plurality of pulse light beams generated by the plurality of pulse light sources being projected on the first beam combiner to combined into one light beam and the combined light beam being projected to the light field control module,
wherein the air ionization display device further comprises:
a first pulse-repetition-frequency adjustment component, arranged between the plurality of pulse light sources and the first beam combiner and configured to adjust pulse repetition frequencies of the plurality of pulse light sources.
