Embodiment 1
[0058] Figure 3a , Figure 4a and Figure 5a The timing corresponding to the pixel circuit shown is as follows Figure 6a When shown, it includes three stages t1, t2 and t3.
[0059] In the t1 stage, S1=0, S2=0, Emit=1.
[0060] The first transistor T1 , the fourth transistor T4 , the fifth transistor T5 , the sixth transistor T6 and the driving transistor T0 are turned on, and the second transistor T2 and the third transistor T3 are turned off. The potential of the first node N1 is the potential Vdata on the data line data, the second node N2=Vint, the third node N3=Vint, the fourth node N4=Vint, and the light emitting diode oled does not emit light. That is, the functions of node initialization and anode reset of the light-emitting diode oled are realized in the t1 stage.
[0061] In the t2 stage, S1=1, S2=0, Emit=1.
[0062] The first transistor T1, the fourth transistor T4 and the driving transistor T0 are turned on, and the second transistor T2, the third transisto...
Embodiment 2
[0066] Figure 3a , Figure 4a and Figure 5a The timing corresponding to the pixel circuit shown is as follows Figure 6b When shown, four stages including t0, t1, t2 and t3 are included.
[0067] At stage t0, S1=0, S2=1, Emit=1.
[0068] The fifth transistor T5 and the sixth transistor T6 are turned on, and the driving transistor T0 , the first transistor T1 , the second transistor T2 , the third transistor T3 and the fourth transistor T4 are turned off. The fourth node N4=Vint, the potential of the node connected to the second pole of the sixth transistor T6 is Vint, and the light emitting diode oled does not emit light. That is, the functions of node initialization and anode reset of the light-emitting diode oled are realized in the t0 stage.
[0069] In the t1 stage, S1=0, S2=0, Emit=1.
[0070]The first transistor T1 , the fourth transistor T4 , the fifth transistor T5 , the sixth transistor T6 and the driving transistor T0 are turned on, and the second transistor ...
