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.

Projection device and display method thereof

An illumination system and a projection device are provided. The illumination system includes a light source device, a light homogenizing element, and a polarization element. The light source device is configured to provide first, second, third, and first compensation beams. The light homogenizing element is disposed on transmission paths of the first, second, and third beams and the first compensation beam and is configured to convert the first, second, and third beams and the first compensation beam into an illumination beam. The polarization element is disposed on the transmission paths of the first beam and the first compensation beam and located between the light source device and the light homogenizing element. The first beam and the first compensation beam pass through the polarization element to change polarization states of the first beam and the first compensation beam to be the same as polarization states of the second and third beams.

Illumination system and projection device

A light source module and a projection apparatus comprising the same are provided. The light source module comprises a light source unit, a light splitting element, and a condenser lens. The light source unit is configured to provide first color light beams including a first sub-light beam and a third sub-light beam, and second color light beams including a second sub-light beam and a fourth sub-light beam. The light source unit comprises a first light source unit to provide the first and second sub-light beams, and a second light source unit to provide the third and fourth sub-light beams. One of the first sub-light beam and the third sub-light beam is transmitted to the condenser lens after being reflected by the light splitting element, and the other of the first sub-light beam and the third sub-light beam is transmitted to the condenser lens after passing through the light splitting element.

Light source module and projection apparatus

A photoalignment equipment includes a light emitting device, a platform, a pipe assembly, and a blower. The light emitting device has an ultraviolet light source and an accommodating space. The ultraviolet light source is located in the accommodating space. When the ultraviolet light source emits an ultraviolet light, at least a portion of air in the accommodating space is transformed into a plurality of ozone molecules. The platform is under the light-emitting device. The pipe assembly has a first opening and at least one second opening. The first opening is communicated with the accommodating space, and the second opening faces the platform. The blower is communicated with the pipe assembly to draw the ozone molecules in the accommodating space by the first opening of the pipe assembly and exhausts the ozone molecules from the second opening of the pipe assembly.
