1. A display device, comprising:
a plurality of scan lines;
a plurality of data lines; and
a plurality of pixel modules, each of the pixel modules comprising:
a switching circuit electrically connected to one of the scan lines, and receiving a scanning signal of the scan lines in one stage via the one of the scan lines; and
a plurality of pixel circuits electrically connected to the switching circuit, and receiving the scanning signal, wherein each of the pixel circuits comprises a light emitting element;
wherein one of the pixel circuits and the switching circuit is electrically connected to one of the data lines, and receives a data signal via the one of the data lines, the switching circuit is controlled by the scanning signal to turn on the pixel circuits, and writes the data signal into each of the pixel circuits in sequence when the pixel circuits are turned on;
wherein each of the pixel modules further comprises:
a compensating circuit directly connected to the switching circuit and the pixel circuits, and comprises:
a first transistor directly connected to the switching circuit, and receiving a light emitting controlling signal;
a second transistor directly connected to the first transistor, and receiving the scanning signal; and
a third transistor directly connected to the first transistor and the second transistor, and receiving another scanning signal of the scan in a previous stage;
wherein each of the pixel circuits comprises:
a capacitor electrically directly connected to the first transistor;
a forth transistor directly connected to the capacitor and the switch circuit;
a fifth transistor directly connected to the capacitor and the forth transistor, and receiving a clock signal;
a six transistor directly connected to the capacitor and the fifth transistor, and receiving the another scanning signal; and
a seventh transistor directly connected to the fourth transistor, the fifth transistor and the light emitting element, and receiving the light emitting controlling signal.
