OLED DISPLAY PANEL WITH THRESHOLD VOLTAGE COMPENSATION AND DRIVING METHOD THEREOF

摘要

In an OLED display panel with threshold voltage compensation, a data programming transistor has a first control end for receiving a first control signal, a first end connected to a data line, and a second end. A driving transistor has a second control end, a third end, and a fourth end. A storage capacitor is connected to the second end and the second control end. A compensating transistor has a third control end for receiving a second control signal, a fifth end connected to the storage capacitor, and a sixth end connected to the fourth end. A compensating capacitor is connected to the third end, the fifth end, and the second control end. A turn-on transistor has a fourth control end for receiving a third control signal, a seventh end connected to the fourth end, and an eighth end connected to an OLED device.
