Abstract

A projection device and its display method are provided. The projection device includes a light source module, a control device, a light valve module, and a lens module. The light source module provides an illumination beam and includes first and second light sources respectively emitting first and second sub-color beams and a driving circuit driving the first and second light sources. The illumination beam includes the first and second sub-color beams. The light valve module converts the illumination beam to an image beam. The lens module projects the image beam. The projection device is configured to have multiple color gamut modes. In at least partial time of a first time slot, the control device controls the driving circuit to simultaneously drive the first and second light sources.
