P-32: A New Driving Pixel Circuit to Alleviate AMOLED Degradation

This study proposes a new driving pixel circuit in an active matrix organic light‐emitting diode (AMOLED). It is designed to decrease current density and supply the operation of negative bias stress for alleviating OLED degradation, while is capable of improving threshold voltage (Vth) shift of thin...

Description
Summary:This study proposes a new driving pixel circuit in an active matrix organic light‐emitting diode (AMOLED). It is designed to decrease current density and supply the operation of negative bias stress for alleviating OLED degradation, while is capable of improving threshold voltage (Vth) shift of thin film transistors (TFTs) by current‐mode compensation circuit.
