模拟缓冲器及其驱动方法，使用其的液晶显示装置及其驱动方法

Analog buffer and driving method thereof, liquid crystal display apparatus using the same and driving method thereof
Abstract:
An analog buffer for buffering an input voltage to an output line is provided. The analog buffer includes a constant current source and a comparator. The constant current source supplies a constant current to the output line, and the comparator compares a voltage charged on the output line with the input voltage to turn-off the constant current source if it is determined that the voltage charged on the output line corresponding to the input voltage is buffered to the output line.
Abstract(Chinese):

提供了用于将输入电压缓冲到输出线的模拟缓冲器。 模拟缓冲器包括恒流源和比较器。 恒定电流源向输出线提供恒定电流，并且比较器将输出线上充电的电压与输入电压进行比较，如果确定在对应于输出线的输出线上充电的电压 输入电压被缓冲到输出线。
