A novel 3-TFT AMOLED pixel driver for threshold voltage shift compensation

A new voltage-programmed pixel using amorphous silicon (a-Si) thin film transistors (TFTs) for active matrix organic light-emitting diodes (AMOLEDs) and its external driver is presented. The proposed pixel circuit is a 3- TFT structure with only 2 controlling signals. This pixel structure along with...

Description
Summary:A new voltage-programmed pixel using amorphous silicon (a-Si) thin film transistors (TFTs) for active matrix organic light-emitting diodes (AMOLEDs) and its external driver is presented. The proposed pixel circuit is a 3- TFT structure with only 2 controlling signals. This pixel structure along with its driver compensates for the shift in TFTs threshold voltage and reduces current sensitivity of OLED to W/L of TFTs.
