<P>PROBLEM TO BE SOLVED: To provide a driving device of a display panel that performs polarity inversion of gradation voltage without deteriorating display quality. <P>SOLUTION: In generating a positive polarity gradation voltage and a negative polarity gradation voltage to be applied to a data line of a display panel based on the amplified gradation voltage obtained by alternately applying a positive polarity gradation reference voltage and a negative polarity gradation reference voltage into an input line of a single amplifier, a gradation voltage with the same polarity as the gradation reference voltage to be applied to the input line after the switching of the gradation reference voltage is applied to the input line immediately before the switching. <P>COPYRIGHT: (C)2012,JPO&INPIT |
