Method of driving data lines, and display device and liquid crystal display device using method

摘要

A method of driving source lines is arranged as follows: One output signal line S61 of a source driver is connected to a plurality of lines corresponding to respective source lines SR7 through SB12, and these source lines from SR7 (starting data line) to SB12 (terminating data line) are grouped as one block (group). In each block, a signal voltage of a divided output is supplied to the source lines during a first horizontal period T, while a signal voltage whose polarity is opposite to that of the aforesaid output is supplied to the source lines in a second horizontal period that is after the first horizontal period. In each of the horizontal periods, the source lines SR7 through SB12 are subjected to sequential selection. In addition to this, the source line SB12 is selected before turning the source line SR7 off. With this, a method of driving source lines, which can restrain (eliminate) the voltage variation on each source line and pixel electrode on account parasitic capacities between source lines, can be realized.
