基于馈通电压自动补偿的 OLED 电性能测试波形设计研究
Design of OLED shorting bar testing waveform based on feed through voltage compensation principle
摘要
Abstract
The conventional calculation principle for the feed through voltage relates to capacitance val-ues of OLED body,and capacitance values of different OLED products is variable.A lot of experi-ments must be done by testing department of OLED manufacturing enterprise in order to get the best capacitance values of OLED body.This paper directly pulls up gate voltage,and then the storage ca-pacitor of OLED body produces a feed through voltage to compensate the feed through voltage genera-ted by the parasitic capacitance between the gate and the drain as the gate voltage closing.Experiment result shows that the total detection rate using the testing waveform based on automatic compensation principle or conventional compensation is consistent,and there is little difference on the detection rate of different defects.关键词
