Patent ID: 11948487
Assignee: LX SEMICON CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A current supply circuit comprising:
a first transistor configured to be supplied with a data driving current through a data line;
a second transistor configured to supply a pixel current to a light emitting diode in response to the data driving current of the first transistor; and
a current compensation circuit connected to the first transistor and the second transistor and configured to adjust a current transferred to the second transistor, wherein
the current compensation circuit is configured to adjust a current flowing between the first transistor and the second transistor through at least one switch transistor,
the current compensation circuit comprises:
a third transistor disposed between the first transistor and the second transistor and connected to a gate terminal of the second transistor, and
a fourth transistor disposed between the first transistor and the third transistor, and

the third and fourth transistors are configured to be turned on and/or off at the same timing.
