Display system and method

A display system, comprising:

• a light source device;
• an optical processing assembly;
• a reflection device;
• and
• a light modulator,
• wherein the light source device is configured to emit a plurality of light beams,
• the optical processing assembly is configured to perform a light path adjustment on each light beam of the plurality of light beams from the light source device in such a manner that the light beam irradiates on the reflection device at a preset light-cone angle,
• the reflection device is configured to reflect the plurality of light beams from the optical processing assembly to the light modulator, and
• the light modulator comprises a plurality of sets of controllable units, each light beam reflected by the reflection device corresponds to a respective set of the plurality of sets of controllable units, and the light modulator is configured to control one or more controllable units in the respective set of controllable units to modulate the light beam corresponding to the set of controllable units, so as to emit desired display light.
