In comparison with the prior art, each driving stage of the driving module has less number of transistors. From the first to the seventh example, each driving stage is implemented by only four transistors. In the eighth example and the ninth example, each driving stage is implemented by only two transistors. In other words, the driving stage of the multiplex gate driving circuit has less number of transistors, thereby reducing the layout area of the invisible zone of the LCD panel. | 05-31-2012 |
