One-bit memory circuit for amoled panel sub-pixels

A one-bit memory circuit for amoled panel sub-pixels, comprising a first MOS transistor, a second MOS transistor, a capacitor, a light emitting diode and an auxiliary latch circuit;

• wherein a gate and a first terminal except the gate of the second MOS transistor are connected to a scan line and a data line respectively, and a second terminal except the gate is connected to a gate of the first MOS transistor via a charge storage point;
• a first terminal and a second terminal except the gate of the first MOS transistor are connected to a first power terminal and a first terminal of the light emitting diode respectively;
• a second terminal of the light emitting diode is connected to a second power terminal;
• both terminals of the capacitor are connected to the charge storage point and the first power terminal respectively;
• and
• the auxiliary latch circuit receives a latch signal and is connected to the charge storage point, and forms a latch together with the first MOS transistor and the light emitting diode for latching the voltage on the capacitor.
