Abstract:
1. A driving device for a display panel in which a pixel composed of sub-pixels of red (R), green (G), blue (B), and at least one other color has a plurality of sub-pixels at least in a vertical scanning direction, and color filters are provided corresponding to the respective sub-pixels, the driving device comprising: an incoming signal interpolating section arranged to interpolate each of the sub-pixels based on incoming color signal components of red (R), green (G), and blue (B) at least in a vertical scanning direction to generate interpolated RGB signals; a luminance signal converting section arranged to convert color signals of interpolated sub-pixels, which are obtained from the incoming signal interpolating section, into luminance signals; a color luminance component adding section arranged to add a luminance signal component of at least one other color on a basis of luminance signal components of colors of red (R), green (G), and blue (B), which components are outputted from the luminance signal converting section; and a luminance reallocating section which reallocates luminance signals of peripheral interpolated sub-pixels, for a color of each of the color filters corresponding to the sub-pixels, in accordance with output from the color luminance component adding section.
