In this work, a 5T2C current-biased voltage-programmed (CBVP) pixel circuit is put forth as the backplane technology for AMOLED displays. The designed pixel circuit uses a very low input bias current (\mathrm{I}_{\text{BIAS}}) of 0.1 \mu \mathrm{A} compared to existing designs. It also compensates for the OLED current (IOLED) error for a maximum 1.35 V threshold voltage shift. The maximum emis...Show More
This work presents a 5T −2C pixel circuit based on amorphous indium gallium zinc oxide (a-IGZO) thin film transistors (TFTs) for flexible displays utilizing improved stacked voltage-programmed pixel circuit topology. Due to a low operating voltage of 5 V and reduced programming time of 8 $\mu\mathrm{s}$, the proposed circuit finds its application in large screen HD displays as it can provide a ver...Show More
