<P>PROBLEM TO BE SOLVED: To prevent malfunction of a touch panel and erroneous operation by reducing the occurrence of coupling noise even in the case of a lighting/non-lighting pixel pattern being worst. <P>SOLUTION: With respect to a driving voltage waveform in a liquid crystal driving method relating to this embodiment shown in Figure 1, a prescribed voltage (±Voff) is applied as a driving voltage for non-lighting display pixels in odd columns (a column 1 in this case). Therefore, coupling noise due to a driving voltage for lighting display pixels in even columns (a column 2 in this case) can be reduced. That is, the prescribed voltage (±Voff) having a polarity opposite to that of the driving voltage for lighting pixels is added to a driving voltage waveform for non-lighting display pixels, so that the action which the driving voltage for lighting display pixels has and causes coupling noise is canceled in some degree by the driving voltage waveform for non-lighting display pixels to reduce the coupling noise. <P>COPYRIGHT: (C)2013,JPO&INPIT |
