显示装置的驱动电路的输出电路与驱动方法
摘要：
本发明提供一输出电路，藉由使用低电压容限度的开关得到具有大电压摆动的输出信号。此输出电路包括：二运算放大器，分别接收正输入电压与负输入电压；二传输门，分别传送前述运算放大器的输出信号；四开关，分别传送前述二传输门的输出信号，作为输出电路的输出信号；拉高其中一个传输门的输出信号；以及拉低另一传输门的输出信号。
摘要（英）：

An output circuit whose outputting signals having large voltage swing by using switches with low voltage tolerance is provided. The output circuit includes: operation amplifiers, receiving positive input voltage and negative input voltages, respectively; transmission gates, passing output signals from the operation amplifiers, respectively; switch transistors, passing output signals from the transmission gates as an output signal of the output circuit, pulling up the output signal from one of the transmission gates, and pulling down the output signal from the other of the transmission gates.
