Abstract:
A pixel circuit includes a circuit element connected to a gate of a first transistor and ground, which receives a select input. A data line is coupled to a first source/drain of the first transistor, and a second source/drain of the first transistor is coupled to a gate of a second transistor. The second transistor has a drain connected to a supply voltage and a source connected to a resistive element. The resistive element connects to an organic light emitting diode (OLED), which connects to the ground.
