The eDP data input interface 112 of the driving apparatus 100 receives the time-sequential color sub-frame image in the order of R sub-frame, G sub-frame, and B sub-frame; the eDP logic analysis module 122 analyzes the time-series color subframe image to obtain analyzed subframe data in a 1-bit single-bit pixel data format; the optical parameter correction module 130 corrects the analyzed sub-frame data by brightness, contrast, gamma curve and the like to obtain corrected sub-frame data; the data restructuring output module 140 restructures the data structure of the corrected sub-frame data according to the display data requirement of the display device 200 to obtain restructured sub-frame data, and sends the restructured sub-frame data to the display device 200, and generates lighting data for driving lighting of the light-emitting material. The display device 200 receives the recombined sub-frame data in the 1-bit single-bit pixel data format, and the data input processing module 210 processes the recombined sub-frame data to obtain sub-frame data to be displayed, and then stores the sub-frame data in the pixel structure of the pixel array module 220 to be displayed at the display time of the next sub-frame.
