Abstract
A drive circuit is provided for an OLED pixel display. The drive circuit is adapted for use with a reference voltage source. It includes a first transistor and an OLED. The output circuit of the first transistor is operably connected between the reference voltage source and the OLED. Transmission gate means responsive to a control signal are provided to transmit a data signal to the first transistor. Means are provided for controlling the first transistor in accordance with a time domain modulation signal to provide an average current to the OLED which is a function of the data signal.
