A high-speed driver for current-programmed active-matrix OLED displays
This paper proposes a new driving technique for improving settling time in current-programmed active-matrix organic light-emitting diode (AMOLED) pixel circuits. Here, a current feedback along with a second generation current conveyer is employed as the driver to cancel the effect of parasitic line capacitances. Circuit-level simulation using a high-voltage CMOS process for external driver and a VerligA model for amorphous silicon thin film transistors shows more than 8 times reduction in programming time of a typical current programmed pixel circuit for programming current of 100nA.
