Claim 12:
13. A driving method for a display panel, comprising:
outputting, by a row scanning circuit, scanning signals to sub-pixels in a display panel for a plurality of times within one frame and outputting, by the row scanning circuit, the scanning signals to the sub-pixels in the display panel in a plurality of sub-frames each time of the plurality of times;
receiving, by a data processor, a display data stream comprising display data corresponding to the sub-pixels in the plurality of sub-frames,
splitting, the display data stream according to analog-bit display data comprised in the display data and digital-bit display data comprised in the display data, and outputting, the split display data stream to a column scanning circuit; and
generating, by the column scanning circuit, according to the analog-bit display data, corresponding data signals of bright-state analog data voltages, and,
transmitting, according to the digital-bit display data, corresponding data signals of dark-state digital data voltages or the corresponding data signals of the bright-state analog data voltages to corresponding sub-pixels in the display panel;
wherein receiving, by the data processor, the display data stream comprising the display data corresponding to the sub-pixels in the plurality of sub-frames, splitting the display data stream according to the analog-bit display data comprised in the display data and the digital-bit display data comprised in the display data, and outputting the split display data stream to the column scanning circuit comprise:
receiving, by the data processor, the display data stream comprising the display data corresponding to the sub-pixels in the plurality of sub-frames and splitting each piece of the display data in the display data stream into the analog-bit display data and the digital-bit display data; and
recombining, by the data processor, the digital-bit display data in the plurality of sub-frames and corresponding to the sub-pixels, recombining digital-bit display data having same digital bits in digital-bit display data corresponding to sub-pixels in a same row into one piece of data, and outputting the data recombined from the corresponding digital-bit display data to the column scanning circuit.
