  • Patent number: 9659032
    Abstract: Systems and methods are described to generate a color palette with color combinations based on human color preferences. One or more input colors can be used to determine affiliated colors based on the presence of colors in color palettes that have been voted on and/or ranked by a community of users. Each affiliated color can be weighted, normalized, and ordered based at least in part on the level of preference for the color palette to which it belongs and the relative popularity of the input colors. A color from the ordered affiliated colors can be selected and added to the custom palette of colors. With the addition of a color, the ordered affiliated colors can be updated to further present colors for inclusion in the custom color palette.

  • Patent number: 9632527
    Abstract: A shift register is configured by connecting unit circuits 1 in multiple stages. An output transistor Tr1 switches between whether or not to output a clock signal CKA in accordance with a gate potential. A drain terminal of an initialization transistor Tra is connected to a gate terminal of the Tr1, and a source terminal thereof is connected to an output terminal OUT or a clock terminal CKA. The source terminal of the Tra is connected to a node which has a low-level potential at the time of initialization and has a potential at the same level as the clock signal when the clock signal having a high-level potential is outputted. Thus, at the time of outputting the clock signal having the high-level potential, application of a high voltage between the source and the drain of the Tra is prevented, and degradation and breakdown of the initialization transistor are prevented.
