Element.
Below in conjunction with Fig. 2 and Fig. 3 work to the image element circuit that the preferred embodiment of the invention provides
Being described in detail as principle, the image element circuit that being illustrated in figure 2 the present invention provides is defeated when working
The sequential chart of the scanning signal entered in each scan signal line, can be divided into five stages, at figure
Reset phase W1, the first discharge regime W2, the second discharge regime W3 it is expressed as in 2,
Compensation saltus step stage W4, glow phase W5, in each stage, the current direction of image element circuit
With magnitude of voltage respectively as shown in Fig. 3 a, Fig. 3 b, Fig. 3 c, Fig. 3 d, Fig. 3 e.For convenience of explanation,
It is further elaborated with each switch element and driver element for N-channel type TFT.
At reset phase W1, as in figure 2 it is shown, in scan signal line, Scan [1], Scan [2],
Scan [3] and EM2 is high level, and Em1 is low level, and data voltage Vdata=V1, V1For
Voltage corresponding to Organic Light Emitting Diode L, now, except T2 and T2 ' disconnects, rest switch
Being both turned on, current direction is as shown in the La in Fig. 3 a, and now Vdd divides the a1 end charging to C,
The voltage potential of a1 end is set to Vdd, and charge to the a2 end of C ', the voltage of a end is set to Vdd,
Simultaneously because T4 and T4 ' conducting, the voltage of b1 point and the voltage of b2 point are all set to V1.
At the first discharge regime W2, as in figure 2 it is shown, in scan signal line, Scan [1], Scan [2],
Scan [3] is high level, EM2 and Em1 is low level, data voltage VdataIt is maintained V1, this
Time T1, T2, T1 ', T2 ', DT, DT ' be both turned on, other TFT turn off, current direction
As shown in Lb1 and Lb2 in Fig. 3 b, now two energy-storage units C and C ' are respectively along Lb1 and Lb2
Electric discharge, owing to the conducting of T5 and T5 ' makes electric current will not pass through L and L ', reduces two indirectly
The loss of electroluminescence cell.After the first discharge regime, b1 point electromotive force and b2 point electromotive force keep
Constant, a1 point electromotive force and a2 point electromotive force reduce to V respectivelyth1And Vth2, V hereth1And Vth2Respectively
Threshold voltage for DT and DT '.
At the second discharge regime W3, as in figure 2 it is shown, in scan signal line, Scan [2], Scan [3]
For high level, Scan [1], Em1, Em2 are low level, data voltage VdataFor V2, V2For
T3 ', T4 ' and DT ' in voltage corresponding to Organic Light Emitting Diode L ', the most only P2 lead
Logical, current direction is as shown in the Lc in Fig. 3 c, and this process is similar, except for the difference that with a upper process
Only having the energy-storage units C ' electric discharge of P2, after having discharged, the current potential of b2 end can become V2, and a2
Point maintains V alwaysth2。
Compensating saltus step stage W4, as in figure 2 it is shown, in scan signal line, Scan [3] and Em1
For high level, other holding wires are low level, the most only T2, T5, T2 ', T5 ' for conducting
State, other TFT are off state, and current direction is as shown in the Ld in Fig. 3 d, now, b1
V is met with b2 pointdd(potential change is V1→Vdd、V2→Vdd), due to a1 and a2 end suspension joint,
Energy-storage units C and C ' two ends realize voltage equal equivalent saltus step, and the pressure reduction before C saltus step is Vth1-V1,
Pressure reduction before C ' saltus step is Vth2-V2, then the electromotive force V of a1 point after saltus stepa1=Vdd+Vth1-V1, a2
The electromotive force V of pointa2=Vdd+Vth2-V2, this process is that glow phase is prepared.
In glow phase W5, as in figure 2 it is shown, in scan signal line, only Em2 is high level,
Conducting that other holding wires are low level, the most only T1, T ', DT, DT ', other TFT close
Disconnected, current direction as shown in the Le in Fig. 3 e, VddTo L and L ' for induced current, L and L ' is made to put
Electricity.
According to saturation current formula, now flow through the electric current I of LL=K (VGS–Vth1)2=
(Vdd+Vth1–V1–VL–Vth1)2=K (Vdd–V1–VL)2。
In like manner, IL’=K (Vdd–V2–VL’)2。
By in above formula it can be seen that the operating current now flowing through two electroluminescence cells is not subject to
The impact of drive transistor threshold voltage, only with data voltage V nowdataRelevant.Thoroughly solve
Determined driving TFT due to manufacturing process and for a long time operation cause threshold voltage (Vth) drift about
Problem, eliminates the impact of its electric current on flowing through OLED, it is ensured that electroluminescence cell normal
Work.
