Classification: CPC G | IPC G

Claim 0:
1. A micro light-emitting diode display device, comprising:
a display substrate comprising a plurality of pixels, each of the pixels comprising:
a first subpixel having a first subpixel circuit and a first light-emitting element electrically connected to the first subpixel circuit, and
a second subpixel having a second subpixel circuit and a second light-emitting element electrically connected to the second subpixel circuit, wherein the first subpixel circuit and the second subpixel circuit are configured independently with each other; and
a data driving circuit electrically connected to the first subpixel circuits and the second subpixel circuits via a plurality of data lines;
wherein, the data driving circuit transmits a first data signal to each of the first subpixel circuits to drive each of the first light-emitting elements, the data driving circuit transmits a second data signal to each of the second subpixel circuits to drive each of the second light-emitting elements, the first data signal is a pulse-width modulation (PWM) signal, and the second data signal is a pulse-amplitude modulation (PAM) signal;
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
wherein, in one frame time, the scan driving circuit transmits 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.
