Disclosed herein are a pixel circuit and driving method for active matrix
Organic Light-emitting Diodes (OLEDs), and a display using the same. The
pixel circuit includes a Voltage Control Current Source (VCCS), a high
gain amplifier, a storage capacitor, and first and second switches. The
VCCS is configured to drive OLEDs. The high gain amplifier is configured
such that the control input signal of the VCCS causes the VCCS to be
placed in an ON or OFF state. The storage capacitor is located between
the input terminal of the high gain amplifier and a data line so as to
assign the ON-time of the VCCS. The first and second switches are
configured to be controlled through a scan line so as to store voltage in
the storage capacitor and control the light-emitting time of the OLEDs,
and are formed the input terminal of the high gain amplifier and the
input terminal of the VCCS, respectively.
