Abstract: The present invention provides a patterned wavelength converting structure comprising a frame, a light source, a substrate, a film, a wavelength converting layer and a pattern disposed on the film. The pattern and the wavelength converting layer can be one piece. The configuration, for example, the distribution of diffusion particles, the location, the shape or the thickness, of the pattern is configured to reduce the mura or affect the desired uniformity of a lighting area.

Abstract: The present invention relates to a lighting module and manufacturing Method for the Same, and more particularly, to a lighting module with a flat wavelength converting structure for reducing mura. The lighting module provided by the present invention includes a frame, one or more light sources disposed on the frame, and a flat wavelength converting structure shared by the light sources for emitting light with aimed wavelength; the present invention provides a lighting module emitting light with mura that insensible to eye or with lower mura at elevated diffusion angle compared to that provided by the traditional one; therefore, the present invention also provides a lighting module occupying smaller volume; or a lighting module with fewer light sources and sharing the similar thickness of the traditional one, which emits light with similar or lower mura compared to the traditional one.

Abstract: A light source package module with a wavelength converting structure is provided. The light source package module comprises a frame having a substrate and sidewalls formed on the substrate. A plurality of LED dice is disposed on the substrate, and there is a space between each of the LED dice. A wavelength converting structure is disposed on above the plurality of LED dice and the sidewalls. The light source package can provide a flat light source with a large emitting area can be made in simply as well. Additionally, the present invention further relates to the application of a backlight module.

Abstract: The disclosed invention relates to black multi-layer coatings for metallic substrates (1) or substrates having a metallic coating (2) and to articles covered, or partially covered with such coatings. The black coating consists of a black first layer (3) substantially comprised of nickel and a second polymeric silicate inorganic layer (4). The present invention may additionally have a third layer comprised substantially of organic constituents (5). This invention offers properties currently unavailable or insufficient in existing technologies. The present invention provides enhanced corrosion resistant, adherent black coatings which are thin enough to allow application to fasteners while providing a uniform black color, the combination of which have only been available previously with the use of hexavalent or trivalent chromium conversion coatings.

Abstract: The present invention discloses a method of forming internal scattering pattern in the diffusion plate and light guide plate used in backlight module by laser engraving. In the present invention, the distribution and density of the engraved dots can be controlled and modulated depending on the position of the light source and the distribution of luminance to obtain higher luminance and better luminance uniformity.
