  • Patent number: 8373818
    Abstract: A multiple primary color display device according to the present invention includes a pixel defined by a plurality of sub pixels. The plurality of sub pixels include a first sub pixel to display a first color having a first hue, a second sub pixel to display a second color having a second hue, a third sub pixel to display a third color having a third hue, and a fourth sub pixel to display a fourth color having a fourth hue. When a color represented by the input signal is changed from black to white via a color of a prescribed hue, luminance levels of the plurality of sub pixels are set such that the luminance level of each of the first sub pixel, the second sub pixel and the third sub pixel is started to be increased without increasing the luminance level of the fourth sub pixel and such that the luminance level of the third sub pixel is increased at a lower rate than that of the luminance level of each of the first sub pixel and the second sub pixel.

  • Publication number: 20100321356
    Abstract: A thin-film transistor (1) of the present invention which (i) is used in a path in which a current flows in a given single direction and (ii) has high-concentration impurity regions (3 and 4) which are provided on both sides of a channel region (5) has a low-concentration impurity region (6) which is provided to be sandwiched only between (i) one of the high-concentration impurity regions (3 and 4) into which carriers corresponding to a polarity of the high-concentration impurity regions (3 and 4) move in accordance with the given single direction and (ii) the channel region (5). This provides a thin-film transistor which is less affected by a display signal and carries out on/off control with respect to an output signal of a photodetector that is provided in a pixel which constitutes a display screen of a display device.
