Classification: CPC G | IPC G

Claim 0:
1. A current mirror circuit comprising:
a first transistor configured to be supplied with a data current from a data driving circuit;
a second transistor configured to drive a light emitting diode by mirroring the data current transferred to the first transistor;
a capacitor disposed between the first transistor and the second transistor and configured to store a voltage of a gate terminal of the second transistor; and
a first switch disposed between the first transistor and the second transistor and configured to adjust an input current of the gate terminal of the second transistor, wherein
the first switch comprises:
a third transistor disposed between the first transistor and the second transistor, and
a fourth transistor connected to a common node, to which a terminal of the first transistor and an output node of a second switch are connected, and an input node of the third transistor, and

the third transistor and the fourth transistor are configured to operate at the same timing.
