  • Patent number: 11049450
    Abstract: A pixel circuit and a pixel circuit driving method. The pixel circuit includes four transistors, two scan signal lines, a data signal line, a control signal line, a capacitor, and a LED. The first transistor has a source electrode connected to a first plate of the capacitor, and a drain electrode connected to a source electrode of the second transistor. A second plate of the capacitor is connected to a drain electrode of the third transistor. The second transistor has a drain electrode connected to a gate electrode of the fourth transistor, and the source electrode connected to the data signal line. The third transistor has a source electrode connected to the power source, and the drain electrode connected to a source electrode of the fourth transistor. A drain electrode of the fourth transistor is connected to the LED. A cathode of the LED is connected to ground.
