20160109624 | Radial Lenticular Blending Effect - A method of integrating a radial zoom effect with a complementary radial image transition effect includes integrating the effects such that the two blended radial effects share a common center, and thereby share common displacement paths during the perceived transition. In addition to the visual appeal of the effect, the invention also resolves operational incompatibilities between the practice of commercial photography and the practice of lenticular printing. A lenticular product is formed in accordance with this method. | 2016-04-21 |

20160109626 | COLOR FILTER AND LIQUID CRYSTAL DISPLAY DEVICE - A color filter includes at least one blue color resist including a blue pigment and a violet dye, in which the ratio of the blue pigment to the blue color resist is in a range from 84.2% to 88.8% by weight, the ratio of the violet dye to the blue color resist is in a range from 11.2% to 15.8% by weight, so that a blue light with a y coordinate in a range from 0.045 to 0.051 in the CIE chromaticity diagram is generated when light passes through the blue color resist. Furthermore, a liquid crystal display device employing the color filter is also disclosed herein. | 2016-04-21 |
20160109627 | PROJECTION APPARATUS - A projection apparatus of the present disclosure includes a light-emitting element for emitting excitation light, a wavelength converter for receiving the excitation light, converting the excitation light into light of a different wavelength, and emitting the converted light as radiation light, and an optical filter for receiving the radiation light. The optical filter reflects long-wavelength light of wavelengths longer than wavelengths of the radiation light. With this configuration, the optical filter reflects long-wavelength light of wavelengths longer than wavelengths of the radiation light, thus being able to prevent the wavelength converter from being irradiated with long-wavelength light, and being able to prevent deterioration of the wavelength converter. | 2016-04-21 |
