Latest Patents

Haraguchi holds a patent for a projection device and projection method. This device comprises a light source and a color wheel that is inserted into the optical path of the light source. The color wheel features a plurality of color segments arranged along its peripheral direction. These segments are designed to transmit various wavelength band components of white light in a time division manner during the rotation of the color wheel. Additionally, a light source driving unit alternates the current to discharge the light source at a period shorter than the rotation period of the color wheel, while reversing the polarity at a timing that switches the segment of the color wheel in the optical path. This innovative approach enhances the quality and efficiency of projection devices.
