| 摘 要： | 本文主要讨论在周边驱动电路中由于加电感补偿可以显著改善粉末直流电致发光(DC-EL)的交流电-光特性.由于加电感补偿除了与AC-EL一样,在相同驱动电压下可以提高亮度及在相同亮度下可以降低驱动电压以外,还可以使DC-EL的亮度随驱动频率而改变.这样也可以使DC-EL实现调频的显示及显象应用(如不加L补偿,是不能实现调频应用的).

| Abstract: | The elctro-optical characteristics of DC-EL panels under AC excitation has been improved by using inductance compensation in peripheral circuits. The brightness of the panels could be improved by a factor of three or more comparing with that without the compensation, uhder the same exciting oltages. For the same brightness level, the driving voltage of the panel with the inductance compensation could be lowered for more than 20 volts. Since the brightness of the panels varies with the excitaion frequency and the width of excitation pulss, it is possible to obtain frequency modulation or pulse-width modulation for alphanumeric or image displays. |
