Display apparatus including display driving circuit and display panel

A display apparatus including a display panel connected to a display driving circuit, the display apparatus comprising:

• a plurality of input pads on the display panel, the plurality of input pads being respectively connected to a plurality of data lines and configured to time-divisionally receive an image signal from the display driving circuit through the plurality of data lines in a first horizontal period;
• and
• a plurality of pixel groups arranged in the display panel, and respectively connected to the plurality of input pads and driven based on receiving the image 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.

A display apparatus, comprising:

• a display driving circuit, including:
• a plurality of output pads;
