Yuki NAMEKATA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10261236
    Abstract: An area light source apparatus includes a first light source and a second light source. Each of the first light source and the second light source is a three-wavelength light-emitting diode. The first light source includes first spectral characteristics including a first peak value at a blue peak wavelength, a second peak value at a green peak wavelength, and a third peak value at a red peak wavelength. The second light source includes second spectral characteristics including a fourth peak value at a blue peak wavelength, a fifth peak value at a green peak wavelength, and a sixth peak value at a red peak wavelength. The second peak value is substantially equal to the fifth peak value, and the third peak value is substantially equal to the sixth peak value.

  • Publication number: 20150160401
    Abstract: A backlight includes: a light guide plate on which blue light from the blue LED falls; a quantum dot enhancement film laminated on the light guide plate and configured to convert blue light passing therethrough into light having peak characteristic for green and red; a frame configured to house the light guide plate and the quantum dot enhancement film, and an inner peripheral surface of the frame has a reflectivity not higher than 50% with respect to the blue light from the blue LED.
