Patent ID: 8223177

Claim:
A system for driving a pixel circuit in an active matrix display, comprising: a pair of switching transistors for connecting a pixel circuit to a data line and a feedback line during a programming cycle; a driver for driving the data line during the programming cycle, a select line connected to the gates of said switching transistors for turning on said switching transistors during said programming cycle and turning off said switching transistors at the end of said programming cycle, said driver including: a feedback mechanism for producing a data signal on the data line based on a difference between a feedback signal on the feedback line from the pixel circuit and a programming signal on a programming signal line, and a controller for enhancing the programming speed of the pixel circuit, the controller providing the programming signal on the programming signal line, the programming signal comprising: a primary pulse for boosting the charging of a capacitance of the feedback line and a subsequent pulse with programming data to drive the data line based on the data signal during a single programming cycle.
