Abstract: A color display device determines a relationship between RGB components of an input color image signal in terms of their gradation levels, and carries out a different calculation for each input color image signal depending on which of six patterns of the relationship that the input color image signal belongs to. Further, the color display device carries out the calculation for each of the RGB components excluding a component with a smallest gradation level, using variables that vary depending on the respective gradation levels of the RGB components.

Abstract: A device is provided for setting a voltage applied to each of data signal lines so as to correct a voltage, applied to the pixel, which corresponds to a gradation data signal in each of sub-frames of a single frame. As such, voltage drop, caused by a combination of voltages of the gradation data signal in each of the sub-frames, may be partially or even fully compensated. On this account, it is possible to provide a liquid crystal display device which can lessen or even avoid an influence of the voltage drop caused by, for example, gate-drain capacitance of the thin film transistor in case of adopting time-division driving, and/or a method for driving the liquid crystal display device.
