The embodiment relates to a data driving device for driving pixels of a display panel. In the data driving device, two adjacent DACs can have different gate loads for the same gray level value so that the fluctuation of the gate load according to the gray level value is reduced.

Data driving device

A display driving apparatus includes an output control circuit configured to, with one frame being divided into a plurality of blank periods by touch driving, output source signals corresponding to display data during the plurality of blank periods; and a polarity control circuit configured to receive pre-polarity control information for polarity inversion, and control polarities of the source signals outputted from the output control circuit, for polarity inversion by the unit of vertical 2 dots for one frame, wherein polarities for pre dummy lines and active data lines of odd-numbered and even-numbered blank periods are controlled by the pre-polarity control information.

Display driving apparatus with vertical two dot polarity inversion

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.
