Latest Patents

One of Otani's latest patents is a projection display device. This device includes a light source unit that emits white light along a first optical axis. It features a lighting unit that splits the white light into predetermined color lights and uniformizes their illuminance distribution. Additionally, it incorporates an image generator with a display element that modulates the color lights, along with a projection lens that projects the modulated image light. The device also includes an optical path switching unit that selectively switches between reflection and transmission of the white light, a light diffuser that spreads the white light to a desired illumination area, and a controller that manages the switching between image light and illumination light.

Another notable patent is a light source device and projection display apparatus. This device consists of first and second light source units, a polarization beam splitter, and a polarization conversion element. The first light source unit emits first linear polarization light in one direction, while the second unit emits it in the opposite direction. The polarization beam splitter reflects the emitted light in a perpendicular direction, enhancing the overall performance of the projection system.
