Abstract: By adding multiplexing units to selectively transmit signals associated with a functional circuitry of an IC die to test pads, a probe card with less pin counts than the pad number of the IC die can be utilized for testing the functional circuitry. Therefore, the pad number/pad pitch of the IC die is not limited by the pitch of the conventional probe card. A high pin count IC die design is thereby available.

Abstract: A pixel circuit has a light emitting diode, a first driving transistor, a second driving transistor, a capacitor, and a switch unit. When a scan signal is asserted, the switch unit couples sources/drains of the second driving transistor respectively to a first and a second source/drain of the first driving transistor, and couples a gate and second source/drain of the first driving transistor together. When the scan signal is de-asserted, the switch unit decouples one of the sources/drains of the second driving transistor from the first/second source/drain of the first driving transistor, and decouples the gate from the second source/drain of the first driving transistor.
