As shown in Figure 1, in step S110, start.
In step S120, whether detecting system enters standby mode;When the system enters standby mode, entrance is next Step;Conversely, jumping to step S160.
In exemplary embodiment, the standby mode refers to that the power key of system is quickly pressed, and system is still run, and is only shielded Curtain knocks out, i.e. dormant state, and different from usually said shutdown, and shutdown is that whole system is closed.The wherein described standby splashette When referring to that system enters suspend mode, the scintillations such as white screen or flower screen occur for AMOLED screen, sometimes each time with flicker, Do not occur every time.
In the lower electric sequential of step S130, setting STE signals the STE signals are closed to the first level.
In exemplary embodiment, wherein first level is high level.
In exemplary embodiment, wherein first level is low level.Specific first level be high level still Low level is related with the triode-type, panel circuit structure, the control signal of external circuit that are used in the AMOLED screen, As long as it can realize that the purpose for closing the STE signals belongs within the protection domain of the disclosure.
Into standby mode, screen is closed, and associated voltage is disconnected.Level height in the disclosure is patrolled generally directed to number Circuit is collected, in logic circuits, low level indicates 0, and high level indicates 1.General provision low level is 0~0.25V, and high level is 3.5~5V.But also there are others possible, such as the voltage of battery can be reduced with the passage of usage time in a mobile device, such as If fruit provides the minimum 3.5V of high level, the usage time of possible equipment can substantially reduce, at this time defined high level voltage Can be lower, it is minimum to have 1.7V or so.
In step S140, the source output signal that driving chip is arranged is the first grayscale value during black picture.
In exemplary embodiment, wherein first grayscale value is V0.Usual screen intensity is divided into 256 grayscale, from 0- 255, because being voltage output, write V0 (V255 hereinafter is same reason).
For example, the V0 can be high level, and V255 can be low level;Or the V0 is low level, it is described V255 is high level.Similarly, three poles for being also and being used in the AMOLED screen are arranged in the low and high level of the V0 and V255 Tubing type, panel circuit structure, the control signal of external circuit are related, specifically can be according to actual circuit design value.
