Classification: CPC G | IPC G

Claim 13:
14. A display device comprising:
a first current mirror circuit configured to generate a light-emitting diode (LED) current corresponding to a data current;
a compensation current generation circuit configured to supply a compensation current to the first current mirror circuit; and
a data processing circuit for controlling the LED current transmitted to an LED of the display device, wherein
the data processing circuit is configured to control the LED current by transmitting a current control signal to change the data current or the compensation current, and
the compensation current generation circuit includes a first current source comprising a transistor configured to output a base current defined by a data voltage, and a second current source configured to form a common node by being electrically connected to one terminal of the first current source and to output a direct current.
