Abstract

A display driving apparatus includes an internal reference voltage generation circuit configured to generate and provide an internal reference voltage; a sensing circuit configured to simultaneously sense pixel signals provided from pixels of a display panel and the internal reference voltage, and output a reference voltage sensing signal generated by sensing of the internal reference voltage and pixel sensing signals generated by sensing of the pixel signals; and an output circuit configured to sequentially select the reference voltage sensing signal and the pixel sensing signals, convert the pixel sensing signals into pixel data, convert the reference voltage sensing signal into reference data, and transmits the pixel data and the reference data.
