  • Patent number: 8124315
    Abstract: An optical recording medium contains a recording layer being composed of a phase-change recording material where at least four elements, Ga, Sb, Sn and Ge are contained and the transfer linear velocity is 20 m/s to 30 m/s, and when the wavelength of a recording/reproducing light is within the range of 650 nm to 665 nm and the recording linear velocity is 20 m/s to 28 m/s, the refractive index Nc and the extinction coefficient Kc in a crystalline state and the refractive index Na and the extinction coefficient Ka in an amorphous state in the recording layer respectively satisfy the following numerical expressions: 2.0?Nc?3.0, 4.0?Kc?5.0, 4.0?Na?5.0, and 2.5?Ka?3.1, and information is recordable at the range of 20 m/s to 28 m/s of recording linear velocity.

  • Patent number: 8034517
    Abstract: A manufacturing method of a color filter comprising the following steps is provided. At first, a transparent substrate is provided. Next, a black matrix is formed on the transparent substrate to define a plurality of pixel areas on the transparent substrate. Then, an isolation layer is formed and patterned on the black matrix and then Red/Green/Blue color filter inks are filled into each of the pixel areas separately by inkjet printing. After that, the color filter inks are dried to form color filter units and optionally the isolation layer can further be patterned to form plenty of photo spacers on the black matrix. The isolation layers prevented the color filter inks from spilling out of the pixel areas and color mixing problems during color filter inkjet fabrication. Besides, it is characterized that the color filter units can be formed with even thickness.
