Abstract:
1. An organic light emitting diode (OLED) display device, comprising: a first transistor directly connected to a data line and a first node, configured to transfer a data voltage from the data line to the first node; a second transistor directly connected to the first node and a second node, wherein the first node is directly connected to the first transistor; a third transistor directly connected to a reference voltage terminal and a third node, configured to transfer a reference voltage from the reference voltage terminal to the third node, wherein the third node is directly connected to a gate of a driving transistor; a fourth transistor directly connected to an initialization voltage terminal and the second node, configured to transfer an initialization voltage from the initialization voltage terminal to the second node; a fifth transistor directly connected to the reference voltage terminal and the second node; the driving transistor having a source connected to the second node, the gate connected to the third node, and a drain connected to a high-level power supply voltage terminal; and an OLED connected to a low-level power supply voltage terminal and the second node.
