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.
