Abstract:
1. A driving circuit of an OLED including a scan line driving circuit configured to apply sequentially a selecting signal or an unselecting signal to a plurality of scan lines; a data line driving circuit configured to apply a voltage corresponding to image information to a plurality of data lines; and a pixel circuit arranged in each point where the scan lines and the data lines are intersected, wherein the pixel circuit comprises: a first transistor of which a gate terminal is connected to a [N−1] a second transistor of which a drain terminal is connected to the source terminal of the first transistor, and a gate terminal is connected to a N a third transistor of which a drain terminal is connected to the source terminal of the second transistor, and a gate terminal is connected to the source terminal of the first transistor and the drain terminal of the second transistor, a fourth transistor of which a gate terminal is connected to a N a fifth transistor of which a drain terminal is directly connected without any intervening terminals to the source terminals of the third and fourth transistor, and a gate terminal is directly connected without any intervening terminals to a [N−1] a sixth transistor of which a drain terminal is directly connected without any intervening terminals to the power supply voltage V a capacitor of which one terminal is connected to the drain terminal of the sixth transistor and the power supply voltage V an OLED of which an anode terminal is connected to the sources of the fifth and sixth transistor.
