    • Disclosed herein is a method for level equalization. In this method, a first optical amplifier having a gain tilt coefficient defined as a change in gain tilt to a unit change in gain is first provided. A second optical amplifier having a gain tilt coefficient different from the gain tilt coefficient of the first optical amplifier is cascaded to the first optical amplifier. The gains of the first and second optical amplifiers are distributed so that a level tilt of light amplified by the first and second optical amplifiers becomes substantially flat. Thus, it is possible to provide a simple method for allowing automatic level equalization by providing a plurality of optical amplifiers having different gain tilt coefficients and distributing the gains of these optical amplifiers so that a level tilt of light amplified by these optical amplifiers becomes substantially flat.
    • 这里公开了一种用于电平均衡的方法。 在该方法中,首先提供具有增益倾斜系数的第一光放大器,该增益倾斜系数被定义为增益倾斜的变化与增益的单位变化。 具有与第一光放大器的增益倾斜系数不同的增益倾斜系数的第二光放大器级联到第一光放大器。 分散第一和第二光放大器的增益,使得由第一和第二光放大器放大的光的电平倾斜变得基本平坦。 因此,可以提供一种通过提供具有不同增益倾斜系数的多个光放大器来允许自动电平均衡的简单方法,并且分配这些光放大器的增益,使得由这些光放大器放大的光的电平倾斜变得基本平坦 。

    • The present invention relates to a driving method for displaying television signals on an X-Y matrix type liquid crystal display panel having both switching elements and memory elements for respective picture elements which utilizes the phenomenon that high frequencies reduce the erasing time of the liquid crystals. According to the present invention, when a panel is driven by means of a line at a time process, each horizontal scanning period is divided into two periods, a video signal period and a erasing signal period, thereby to provide a composite signal having a video signal portion and an erasing signal portion so that a first pulse corresponding to the video signal period writes the video signal on that panel and a plurality of second pulses corresponding to the erasing signal period applies the erasing signal to the panel for erasing.
    • 本发明涉及一种用于在具有高频降低液晶擦除时间的现象的X-Y矩阵型液晶显示面板上显示电视信号的驱动方法,其具有用于各个图象的开关元件和存储元件。 根据本发明,当时间处理通过线驱动面板时,将每个水平扫描周期分为视频信号周期和擦除信号周期两个周期,从而提供具有视频的复合信号 信号部分和擦除信号部分,使得对应于视频信号周期的第一脉冲将视频信号写入该面板,并且与擦除信号周期相对应的多个第二脉冲将擦除信号施加到面板进行擦除。
