Abstract: A driving method of a display panel is provided, including setting the first red, first green, first blue, second red, second green, and second blue multiplexed signals. In the 2i−1th multiplexing period, the charging time of the sub-pixels corresponding to the switching units controlled by the first red, the first green, and the first blue multiplexed signals is earlier than that controlled by the second red, the second green, and the second blue multiplexed signals. While In the 2ith multiplexing period, the charging time of the sub-pixels corresponding to the switching units controlled by the first red, the first green, and the first blue multiplexed signals is later than that controlled by the second red, the second green, and the second blue multiplexed signals. The method will eliminate the stripe feeling of the scream picture displayed on the display panel and so improve the display quality.

Abstract: A multiplexing circuit is provided. The multiplexing circuit includes a first multiplexing unit. The first multiplexing unit is configured to receive a signal at a first output end of a source driving circuit of a display and configured to transmit the signal to a pixel of the display. The first multiplexing unit includes a first switching unit configured to control transmitting of the signal to a first sub-pixel of a first pixel of the display. The first switching unit includes a first switch and a second switch. Both the first switch and the second switch are electrically connected between the first output end and the first sub-pixel of the first pixel. The first switch and the second switch are configured to simultaneously turn on or turn on only one to transmit the signal to the first sub-pixel of the first pixel.

Abstract: According to a drive method for the display panel, m multiplex signals sequentially generate the high level pulse at the beginning of the (2i−1)th row period in a predetermined order. The high level pulse of the multiplex signal that is the last one to generate the high level pulse in the (2i−1)th row period continues until the end of the (2i−1)th row period. The m multiplex signals sequentially generate the high level pulse at the beginning of the (2i)th row period in a reverse order to the predetermined order. The high level pulse of the multiplex signal that is the last one to generate the high level pulse in the (2i)th row period continues until the end of the 2i row period. As a result, the number of times that the levels of the multiplex signals are changed in a frame period can be decreased to reduce the power consumption.

Abstract: A drive method for a display panel is provided. A first multiplex signal, a second multiplex signal, a third multiplex signal, a fourth multiplex signal, a fifth multiplex signal, and a sixth multiplex signal sequentially generate the high level pulse in the predetermined order in each of the first row periods of the (2i−1)th multiplex period. In addition, the first multiplex signal, the second multiplex signal, the third multiplex signal, the fourth multiplex signal, the fifth multiplex signal, and the sixth multiplex signal sequentially generate the high level pulse in a reverse order to the predetermined order in each of the second row periods of the (2i)th multiplex period. As a result, mura within the display picture of the display panel is eliminated to improve the display quality.
