Abstract:
1. A source driver circuit for use in a display panel, the source driver circuit comprising: a plurality of digital-to-analog converting units; and a plurality of sampling-transmitting units, each of the sampling-transmitting units comprising: in the second period, the first and second output enable signals are sequentially enabled, and the first and second input enable signals are disabled so that the first sub-latch unit and the second sub-latch unit sequentially output the first pixel data and the second pixel data to the corresponding digital-to-analog converting unit via the transmission channel set; and in a third period, the third and fourth output enable signals are sequentially enabled and the third and fourth input enable signals are disabled so that the third sub-latch unit and the fourth sub-latch unit sequentially output the third pixel data and the fourth pixel data to the corresponding digital-to-analog converting unit via the transmission channel set.
