Disclosed is a display driving device that supports accurate correction of the characteristics of pixels by reflecting the characteristics of a source driver in realtime. The display driving device may include: a sensing circuit configured to sense pixel signals for correcting characteristics of pixels of a display panel and sense at least one reference signal for correcting characteristics of a source driver when sensing the pixel signals; and an analog digital converter configured to convert the pixel signals and the at least one reference signal sensed by the sensing circuit into pixel data and reference data, and to transmit the pixel data and the reference data.

Display driving device

Disclosed are a display device and a panel compensation method of the display device. The panel compensation method of the display device includes a step of allowing at least one line pixel of a display panel to be a current source that generates a pixel current with the same value, and a step of correcting a deviation between all current sensing paths of a source driver by using the pixel current with the same value and correcting a characteristic deviation between all pixels after correcting the deviation between the current sensing paths.
