Think 0V；The absolute value of second driving voltage is less than the absolute value of third driving voltage.Wherein, the voltage value of the second driving voltage
Can be-(| Vb |-Vm)；Wherein, | Vb | for Organic Light Emitting Diode saturation point voltage absolute value, Vm be less than or equal to
0.6 voltage value；The voltage value of third driving voltage can be-(| Vb |+Vn)；Wherein, Vn is the voltage value greater than 0.6；Have
The value range of the absolute value of the saturation point voltage of machine light emitting diode can be 1.6~2.4.Generally, saturation can be chosen
The absolute value of voltage value is 2.0V, Vm=0.6, Vn=0.7；Such second driving voltage can be -1.4V, third driving voltage
It can be -2.7V.In practical application, that is, same technique is worked it out since the manufacture craft of display product has fluctuation
Device, saturation voltage value can also have certain fluctuation.
Specifically, for organic light emitting display panel after RA experiment, selection has just entered the operating voltage of saturation point
Driving display panel is shown can there is the problems such as uneven display and image retention.Specific as follows: laboratory sample A1, A2, A3 are being passed through
The saturation characteristics of RA experiment front and back is crossed as shown in Fig. 2, as seen from Figure 2, after being tested by RA, organic light emitting display
The luminous efficiency of device declines, and driving voltage increases, slower into saturation region.This is because display device passes through high temperature RA
The feelings such as device performance can decline after test, and the cut-in voltage Ion of switching transistor TFT is caused to decline, and blanking voltage Ioff rises
Condition affects the switch performance of switching transistor TFT, be deteriorated so as to cause the picture quality that display device is shown, and image quality

It under light emitting diode cathode voltage PVEE, is shown the result is that when using PVEE=-2.4V, the picture that display panel is shown
The phenomenon that there are ghosts in face, hence it is demonstrated that organic light emitting display panel is after RA experiment, selection just enters saturation point
Operating voltage driving display panel shown that display effect is not good enough.This is because if device works in linear zone, only
There is small fluctuation in the voltage or environment for wanting device, then can bring about biggish current fluctuation, since OLED is shown
Device is current drive-type device, and the variation of driving current is bigger on the influence of the display effect of display, if voltage setting exists
It is saturated point edge, then voltage or external environment change, device is will lead to and biggish fluctuation occurs, in turn result in aobvious
Show the poor problem of device display effect.And working characteristics of the driving transistor for driving OLED luminous in saturation region is with voltage
Its electric current of increase without significant change, therefore choose after saturation region rather than just enter the driving voltage of saturation region, can be with
Guarantee the stability of the luminous driving current of driving OLED, and then is conducive to improve the image quality that device is shown.
