1. A display driving circuit for driving a display panel that includes a plurality of pixel groups, the display driving circuit comprising:
a controller configured to determine a driving order of each of the plurality of pixel groups in a first horizontal period, and to generate image data and a selection signal in a first voltage range;
a data driver configured to generate an image signal on the basis of the image data from the controller, the data driver including a plurality of driving units configured to transfer the image signal to a plurality of data lines in the first horizontal period;
a plurality of output pads respectively connected to the plurality of pixel groups through the plurality of data lines; and
a data switching circuit configured to provide the image signal to the display panel through at least one of the plurality of output pads on the basis of control based on the selection signal;
wherein the display driving circuit includes a thin film transistor (TFT) formed in a first silicon substrate including a single crystal silicon substrate, and
wherein the display panel includes a TFT formed in a second silicon substrate including a polycrystalline silicon substrate or an amorphous silicon substrate.
