A timing control method for an amoled timing control circuit

Abstract

The invention relates to the technical field of display, and discloses a sequential control method of an AMOLED sequential control circuit, which comprises an initialization stage: a power supply voltage is in a low potential state, a data signal line is in an off state or a low potential state to enable no current to pass through an organic light-emitting diode, and the organic light-emitting diode does not emit light; in the adjusting stage, the second thin film transistor is opened; in the data writing stage, the second node writes voltage provided by the data signal line, and the second thin film transistor is closed; in the maintaining stage, the second node maintains the voltage provided by the data signal line written in in the data writing stage; in the driving stage, the second thin film transistor, the fourth thin film transistor and the fifth thin film transistor are opened, and the organic light-emitting diode emits light. In the time sequence control method, the brightnessof the organic light emitting diode is controlled by adjusting the high and low levels of the power supply voltage, and due to the control of the high and low levels of the power supply voltage, thedelay time is reduced, and the adjusting effect of the organic light emitting diode is improved.

Problems solved by technology

[0003] In the above-mentioned AMOLED timing control circuit, the adjustment of the brightness of the organic light-emitting diode is realized by controlling the power supply voltage on and off, but due to the delay time in the process of power supply voltage on and off, the adjustment effect on the organic light-emitting diode is poor
