    • An apparatus for printing a latent image includes a rotary contact, a power supply, driving electronics and a plurality of TFT transistors configured as a TFT backplane. The rotary contact receives serially transmitted digital data signals from a controller and generates selection signals and digital pixel voltages. The rotary contact receives operating voltage signals from the controller. The power supply receives the operating voltage signals from the rotary contact and generates a low voltage signal, a ground signal and a high voltage signal. The driving electronics receive the low voltage signal, the ground signal, selection signals and the digital pixel voltages, and generates bias signals and pixel voltages. The TFT backplane receives the high voltage signal, the bias signals and the pixel voltages, and then drives the hole injection pixels to generate an electrostatic latent image in response to the bias signals and pixel voltages.
    • 用于打印潜像的装置包括旋转触点,电源,驱动电子装置以及配置为TFT背板的多个TFT晶体管。 旋转触点从控制器接收串行传输的数字数据信号,并产生选择信号和数字像素电压。 旋转触点接收来自控制器的工作电压信号。 电源接收来自旋转触点的工作电压信号,并产生低电压信号,接地信号和高电压信号。 驱动电路接收低电压信号,接地信号,选择信号和数字像素电压,并产生偏置信号和像素电压。 TFT背板接收高电压信号,偏置信号和像素电压,然后响应于偏置信号和像素电压驱动空穴注入像素以产生静电潜像。
