Abstract:
1. A data processing device for correcting an image signal, composed of plural pieces of pixel data, which is inputted from an outside source into an active matrix type liquid crystal panel including a plurality of scanning signal lines extending along one direction, a plurality of data signal lines extending along another direction, and a plurality of pixels provided to correspond to points of intersection between the scanning signal lines and the data signal lines, the data processing device comprising: a correction process section for obtaining pixel data to be inputted to a second pixel in which a blue component or a red component is displayed, the second pixel being driven by a data signal line adjacent to a first pixel in which a green component is displayed, and for, if the pixel data to be inputted to the second pixel represents a tone value falls within a range of 0 to a predetermined first value, correcting the tone value to be the first value so as to generate corrected pixel data to be inputted to the second pixel, the correction process section not correcting an input tone value indicated by pixel data which has been inputted to the correction process section and which is to be inputted to the first pixel, and generating pixel data which has an output tone value equal to the input tone value and which is to be inputted to the first pixel, and the correction process section outputting data signals to a data signal driving section for applying the data signals to data signal lines for the first and second pixels so that a reversal of polarities occurs every predetermined number of horizontal periods within a single frame period, the data signals including (i) the pixel data which has the output tone value and which is to be inputted to the first pixel and (ii) the corrected pixel data which has the corrected tone value and which is to be inputted to the second pixel.
