Patent ID: 7956825

Claim:
A circuit for use in a display, the circuit comprising: a first transistor having a first controllable conduction path and a first control electrode configured to control the first controllable conduction path, wherein the first control electrode is further configured to receive a select signal from a select line; a second transistor having a second controllable conduction path and a second control electrode configured to control the second controllable conduction path, wherein the second control electrode is further configured to receive the select signal from the select line; a third transistor having a third controllable conduction path and a third control electrode configured to control the third controllable conduction path, wherein a first end of the first controllable conduction path is connected to the third control electrode, and wherein a second end of the first controllable conduction path is connected to a data line configured to receive a data signal current; and a fourth transistor having a fourth controllable conduction path and a fourth control electrode configured to control the fourth controllable conduction path, wherein a first end of the third controllable conduction path is connected to a first end of the fourth controllable conduction path, wherein the fourth control electrode is connected to the select line, and wherein a second end of the fourth controllable conduction path is configured to provide a current to an organic light-emitting diode (OLED) element.
