摘要：在各种弧焊电源主电路中,逆变弧焊电源主电路的应用最为广泛,因此研究逆变弧焊电源电路的工作特性,对于保证电路的顺利设计有着重要意义。以Multisim软件为仿真平台,设计了逆变弧焊电源主电路,包括三相桥式整流电路、逆变电路、单相输出整流电路,并对所设计电路进行仿真,得出输出电路波形。

摘要：以比铝、银等金属材料透光性更好的铜作为白光有机顶发射器件的顶电极,将其应用到基于Al底电极的蓝、黄互补色顶发射白光有机电致发光器件(TEWOLED),通过合理设计器件结构,制备出的器件具有较低的驱动电压和较高的效率,4V下亮度超过1 000cd/m2、功率效率达到28.5lm/W,效率滚降较小。我们利用p型电学掺杂结构和电子注入缓冲层结构分别解决了铝和铜电极功函数同空穴传输层的HOMO能级和电子传输层的LUMO能级不匹配问题,并通过TcTa光学覆盖层的调节作用使器件具有较好的光谱稳定性。基于Cu顶电极的TEWOLED与采用Al作为互连金属的CMOS工艺兼容,我们将该器件与硅基CMOS驱动电路结合,获得了SVGA白光有机微显示器件,为彩色有机发光微显示的实现奠定了基础。

摘要：A new equivalent circuit model of organic-light-emitting-diode （OLED） is proposed. As the single- diode model is able to approximate OLED behavior as well as the multiple-diode model, the new model will be built based on it. In order to make sure that the experimental and simulated data are in good agreement, the constant resistor is exchanged for an exponential resistor in the new model. Compared with the measured data and the results of the other two OLED SPICE models, the simulated I-V characteristics of the new model match the measured data much better. This new model can be directly incorporated into an SPICE circuit simulator and presents good accuracy over the whole operating voltage.
