Abstract
A pixel circuit for active matrix OLED and driving method is proposed in this invention, which includes five transistors and one capacitance, it's mainly use a first-transistor connected to a control line to let a second transistor connected to the former scan line off when writing a low voltage in, so to avoid large current generation and IR-drop, finally the illumination will be more uniform than prior art.
