摘要： The invention makes it possible to drive a halftone image device and achieve high halftone reproduction by allowing at least one of the leading and trailing edges of a pulse width-modulated signal applied to a recording head, or forming amplitude- and width-modulated pulses, respectively, as driving pulses for placing one dot under halftone control, and changing a pulse width change of pulse width modulation in a stepwise manner, using the pulse width of the amplitude-modulated pulse as a unit pulse width. The invention intends to achieve high-voltage and high-speed pulse output and low power consumption by converting input data such as halftone image data to a voltage signal, superposing pulse voltages of opposite polarities and applying the resulting signal to a switching circuit constituting an output state in the form of a switching signal, and also makes it possible to achieve high speed and high-voltage driving by connecting at least one of equivalent two-terminal elements in series to at least one of the respective driving elements of a complementary FET driving circuit, said equivalent two-terminal elements are each put on with a current of a certain or higher value passing therethrough to show constant-voltage characteristics and put off with a current of a certain or lower value passing therethrough to become a constant resistance.
摘要翻译：本发明通过允许施加到记录头的脉冲宽度调制信号的前沿和后沿中的至少一个或形成幅度和宽度调制脉冲，驱动半色调图像装置并实现高半色调再现，分别作为用于在半色调控制下放置一个点的驱动脉冲，并且使用幅度调制脉冲的脉冲宽度来逐步改变脉宽调制的脉冲宽度变化。本发明旨在通过将诸如半色调图像数据的输入数据转换为电压信号来实现高电压和高速脉冲输出以及低功耗，从而叠加具有相反极性的脉冲电压，并将所得到的信号施加到构成输出的开关电路状态，并且还可以通过将等效的两端元件中的至少一个串联连接到互补FET驱动的各个驱动元件中的至少一个而实现高速和高电压驱动电路中，所述等效的两端子元件各自具有通过其中的一定或更高值的电流以显示恒定电压特性，并且通过其中通过的一定或更低值的电流变为恒定电阻。
