1. A display drive method based on frame data, comprising:
receiving to-be-displayed frame data, and calculating an Average Picture Level (APL) percentage of the frame data by using an analysis unit;
performing High Dynamic Range (HDR) processing on the frame data based on the APL percentage of the frame data, and transmitting the frame data obtained through HDR processing to a display driver circuit; and
driving, by the display driver circuit based on the APL percentage of the frame data, a display to display the frame data obtained through HDR processing,
wherein, after calculating an APL percentage of the frame data by using an analysis unit the method further comprises:
if the analysis unit is a processor or a digital signal processor, transmitting, to the display driver circuit by using the analysis unit, APL interval information in which the APL percentage of the frame data falls, and
wherein the transmitting, to the display driver circuit by using the analysis unit, APL interval information in which the APL percentage of the frame data falls comprises;
determining an APL interval in which the APL percentage of the frame data falls;
generating a corresponding status command based on APL interval information in which the APL percentage of the frame data falls, and
transmitting the status command to the display driver circuit.
