Claim 0:
1. A driving apparatus for a display panel, comprising:
a row scanning circuit configured to
output scanning signals to sub-pixels in the display panel for a plurality of times within one frame and
output the scanning signals to the sub-pixels in the display panel in a plurality of sub-frames each time of the plurality of times;
a data processor configured to
receive a display data stream comprising display data corresponding to the sub-pixels in the plurality of sub-frames,
split 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
output the split display data stream to a column scanning circuit; and
the column scanning circuit electrically connected to the data processor and configured to
generate, according to the analog-bit display data, corresponding data signals of bright-state analog data voltages, and,
transmit, according to the digital-bit display data, generated corresponding data signals of dark-state digital data voltages or the generated corresponding data signals of the bright-state analog data voltages to corresponding sub-pixels in the display panel;
wherein the data processor is configured to:
receive the display data stream comprising the display data corresponding to the sub-pixels in the plurality of sub-frames and split each piece of the display data in the display data stream into the analog-bit display data and the digital-bit display data; and
recombine the digital-bit display data in the plurality of sub-frames and corresponding to the sub-pixels, recombine 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 output the data recombined from the corresponding digital-bit display data to the column scanning circuit.
