Abstract: The present disclosure discloses a display driving device insensitive to external noise. The display driving device may include first and second data wires configured to connect a transmitter of a timing controller and a receiver of a source driver, first and second terminating resistors configured to connect the first and second data wires, and a noise reduction circuit configured to detect a lock fail, generate a common voltage when detecting the lock fail, and provide the common voltage to a node between the first and second terminating resistors. The display driving device can prevent an image failure by minimizing the influence of external noise.

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.
