Abstract: Provided are an output buffer circuit capable of outputting a pair of output signals having different polarities and a display driving circuit including the same. The output buffer circuit includes output buffers which output a positive output signal and a negative output signal in response to a pair of input signals having different polarities. As the output buffers are driven while sharing a common voltage, the output buffer circuit satisfies a low-power specification, and has a stable electrical characteristic.
Abstract translation: 提供了能够输出具有不同极性的一对输出信号的输出缓冲电路和包括该输出缓冲电路的显示驱动电路。 输出缓冲电路包括响应于具有不同极性的一对输入信号而输出正输出信号和负输出信号的输出缓冲器。 由于输出缓冲器在共享公共电压时被驱动，所以输出缓冲电路满足低功耗规格，具有稳定的电气特性。
