Abstract

A one-bit memory circuit for amoled panel sub-pixels is provided with an auxiliary latch circuit and a control switch on the basis of an existing one-bit memory circuit. The control switch is configured for controlling the activation of the auxiliary latch circuit. When the control switch is turned on, the auxiliary latch circuit, together with a voltage-controlled current MOS transistor and a light emitting diode in the existing one-bit memory, forms a latch for latching the voltage on a capacitor in the existing memory circuit. The one-bit memory circuit of the present invention reasonably utilizes components in the existing circuit and cuts down additional components required for achieving the latch function.
