Abstract: Embodiments of the present disclosure relate to a display driving device and a display device including the same. The display driving device includes a source driving circuit configured to convert image data of respective channels into source signals; a polarity control circuit configured to receive polarity data for the respective channels, and generate a polarity control signal for controlling polarities of the source signals depending on a logic combination of the polarity data; and a multiplexer circuit configured to output the source signals to data lines in response to the polarity control signal.

Abstract: Disclosed are a data driving device and a display device including the same. The display device may include: a timing controller configured to include lock fail data in an input signal and transmit the input signal in each preset period; and a source driver configured to recover the lock fail data from the input signal, and reset an internal circuit in response to the recovered lock fail data.
