另一种采用电压控制方式，通过电压的高低进行电机的转速控制，电机的反馈信号通过驱动器反馈到数控系统进行位置控制。

Another kind of the voltage control mode, through the high and low voltage on motor speed control, motor feedback signal through the drive to the numerical control system feedback position control.

同时，为了能够支持点反转和列反转两种面板驱动方式，本数据驱动电路的奇数和偶数输出管脚分别输出极性不同的灰度电压。

Also, to be able to deal with dot-line inversion, this source driver's odd output pins and even output pins respectively output gray scale voltages of differing polarity.
