Abstract: The present disclosure discloses a display device that performs a read operation corresponding to a touch based on a multipoint interface (MPI) protocol. In the display device, a microcontroller and a plurality of drivers share MPI buses and perform the read operation for a touch, and turning on of reception buffers may be efficiently controlled by providing a wake-up signal by a selected driver designated by a read command of the microcontroller to unselected drivers at the time of completion of transmission of touch data.

Abstract: Disclosed are a data driving device and a display device including the same. The display device may include: a timing controller configured to include lock fail data in an input signal and transmit the input signal in each preset period; and a source driver configured to recover the lock fail data from the input signal, and reset an internal circuit in response to the recovered lock fail data.
