Driving apparatus and driving method for display panel, and display apparatus

A display apparatus, comprising a driving apparatus for a display panel and a display panel connected to the driving apparatus for a display panel, wherein the driving apparatus for a display panel comprises:

• 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.
