Abstract
The light source device of the projection display apparatus according to the present disclosure includes: solid-state light sources that individually emit blue light, green light, and red light; a plurality of dichroic mirrors that combine the blue light, the green light, and the red light having exited from the solid-state light sources; a first diffusion plate on which the combined light having been combined by the plurality of dichroic mirrors is incident; a dynamic diffusion plate that is disposed at a position at which the combined light having exited from the first diffusion plate converges and starts to diverge.
Claims13
A light source device, comprising:
- solid-state light sources that individually emit blue light, green light, and red light;
- a plurality of dichroic mirrors that combine, into combined light, the blue light, the green light, and the red light having exited from the solid-state light sources;
- a first diffusion plate on which the combined light having been combined by the plurality of dichroic mirrors is incident;
- a dynamic diffusion plate that is disposed at a position at which the combined light having exited from the first diffusion plate converges and starts to diverge;
- and
- a second diffusion plate on which the combined light having exited from the dynamic diffusion plate is incident, the combined light being divergent light.
Dependencies are inferred from the claim text.
