The output data from each multiplexing unit is output to the data output module 73.

During the implementation, the data transmission module may include 12 groups of multiplexing units, and each group of multiplexing units may include 12 multiplexing units, i.e., 144 display data may be provided by the data transmission module simultaneously.

Optionally, the driving module includes F serial-parallel conversion circuits and F data providing circuits; where F is an integer greater than 1, and f is a positive integer less than or equal to F; at least one of the F serial-parallel conversion circuits is configured to provide address data to the address processing circuit; at least one of the F serial-parallel conversion circuits is configured to provide a common electrode voltage corresponding to a current display mode; an f-th serial-parallel conversion circuit is electrically connected to an f-th data providing circuit, and is configured to output the input display data carried by the parallel output signal generated by the f-th serial-parallel conversion circuit to the f-th data providing circuit; and the f-th data providing circuit is configured to convert the input display data carried by the parallel output signal generated by the f-th serial-parallel conversion circuit to obtain f-th output display data and transmit the f-th output display data to a corresponding data line.

During the implementation, it is assumed that a system clock period is 500 ns and the resolution of the display panel is 200×200. It means that in a color display mode, 6+10+600 data are transmitted on each row, i.e., the time for refreshing the pixel circuits arranged in each row in the display panel is 308 us. It means that the higher the lateral resolution is, the larger the amount of data per row is, and the longer it takes to refresh the pixel circuits arranged in each row in the display panel.

When the lateral resolution is increased, the amount of display data corresponding to the pixel circuits arranged in each row is increased, it is able to shorten the row refreshing time through increasing the number of the serial-parallel conversion circuits and the number of the data providing circuits. Taking a display product with Extended Graphics Array (XGA) resolution as an example, the driving module includes 16 serial-parallel conversion circuits and 16 data providing circuits, and the serial input signal is also split into 16. For a high-resolution display product, the display data may be split to shorten the row refreshing time, i.e., the display data may be split into 16 groups, and each group of data includes 144 data. When the 16 groups of data are refreshed synchronously, the row refreshing time is 80 us, and the row refreshing time is greatly shortened. During the implementation, the number of the serial-parallel conversion circuits and the number of the data providing circuits may be increased in accordance with the requirement of the lateral resolution, so as to shorten the refreshing time of a single row.
