Device, can also there is certain fluctuation in saturation voltage value.
Specifically, organic electroluminescence display panel is selected just into the operating voltage of saturation point after testing through RA
Drive display floater to be shown, can there are problems that showing it is uneven and.It is specific as follows：Laboratory sample A1, A2, A3 are in Jing
The saturation characteristics crossed before and after RA experiments as shown in Fig. 2 as seen from Figure 2, after RA experiments, organic light emitting display
The luminous efficiency of device declines, and driving voltage is raised, slower into saturation region.This is because display device is through high temperature RA
Device performance can decline after test, and the cut-in voltage Ion for causing switching transistor TFT declines, the feelings such as blanking voltage Ioff risings
Condition, that is, have impact on the switch performance of switching transistor TFT, so as to the picture quality for causing display device to show is deteriorated, and image quality
The most direct visual experience that is deteriorated is exactly the phenomenon that ghost and luminous efficiency are reduced occur.

After testing through RA, the operating voltage just into saturation point is selected to drive display floater to be shown, its display effect
It is not good enough.If this is because device is operated in linear zone, as long as the voltage or environment of device occur in that small fluctuation, then
Larger current fluctuation is can bring about, because OLED display is current drive-type device, the change of driving current is to display
Display effect affect than larger, if voltage is arranged on saturation point edge, then voltage or external environment change, just
Device can be caused larger fluctuation occur, in turn result in the poor problem of display display effect.And drive the luminous drives of OLED
Operating characteristic of the dynamic transistor in saturation region is, as the increase of voltage its electric current is without significant change, therefore to choose after saturation region
Rather than just into the driving voltage of saturation region, it is ensured that drive the stability of the luminous driving currents of OLED, Jin Eryou
