Claim 13:
14. A driving method of a micro light-emitting diode display device, wherein the display device comprises a display substrate and a data driving circuit, the display substrate comprises a plurality of pixels, each of the pixels comprises a first subpixel and a second subpixel, the first subpixel has a first subpixel circuit and a first light-emitting element electrically connected to the first subpixel circuit, the second subpixel has a second subpixel circuit and a second light-emitting element electrically connected to the second subpixel circuit, the first subpixel circuit and the second subpixel circuit are configured independently with each other, and the data driving circuit is electrically connected to the first subpixel circuits and the second subpixel circuits via a plurality of data lines, the driving method comprising steps of:
the data driving circuit transmitting a first data signal to each of the first subpixel circuits to drive each of the first light-emitting elements; and
the data driving circuit transmitting a second data signal to each of the second subpixel circuits to drive each of the second light-emitting elements;
wherein, the first data signal is a pulse-width modulation (PWM) signal, and the second data signal is a pulse-amplitude modulation (PAM) signal; and
wherein, the display device further comprises a scan driving circuit electrically connected to the first subpixel circuits and the second subpixel circuits via a plurality of scan lines, and the driving method further comprises a step of:
in one frame time, the scan driving circuit transmitting at least two times of scan signals to drive the first subpixel circuits, so that the data driving circuit provides the corresponding first data signals to the first subpixel circuits so as to control the first light-emitting elements to emit light.
