Abstract (en)
A precharge-circuit (300) charges the organic light emitting diode (OLED) (112) strictly to a positive voltage level, before closing the active switch (118) comprising the metal oxide semiconductor field effect transistor (MOSFET). Independent claims are also included for the following: (1) an arrangement of an OLED array; (2) a common anode, passive matrix organic light emitting diode display; and (3) method for pre-charging an OLED.
