1. A display module, comprising a display panel and a display driver, wherein
the display panel comprises a first pixel scan circuit and a second pixel scan circuit, wherein the first pixel scan circuit is configured to drive pixels in a first area on the display panel to convert electrical signals into optical signals, and the second pixel scan circuit is configured to drive pixels in a second area on the display panel to convert electrical signals into optical signals; and
the display driver is configured to generate different display drive signals to the display panel to respectively control working time periods of the first pixel scan circuit and the second pixel scan circuit,
wherein the different display drive signals comprise a first display drive signal and a second display drive signal, wherein the first display drive signal controls the first pixel scan circuit to be in a working state in a first time period to drive the pixels in the first area, the second display drive signal controls the second pixel scan circuit to be in a working state in a second time period to drive the pixels in the second area, and the first time period and the second time period are periodically cyclic.
