Abstract: Disclosed is a driving apparatus for a display, which drives pixels using a double rate driving (DRD) method. The driving apparatus includes a first latch circuit storing first pixel data, a second latch circuit storing second pixel data, a first selection circuit selecting one of the first pixel data and the second pixel data and outputting selection data, and a second selection circuit selecting one of the selection data of a pair of adjacent first selection units and outputting source data.

Abstract: Disclosed is a system for a display, which drives pixels using a double rate driving (DRD) method. The system includes a timing controller configured to provide a data packet and a lock signal, and a plurality of drivers each configured to restore display data and a clock of the data packet and output a source signal corresponding to the display data using the clock. The lock signal is fed back to the timing controller via the plurality of drivers. Each of the drivers outputs an internal lock signal, obtained by updating the lock signal with information on a restored clock, in next order. Each of the drivers may operate in a low power mode.

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.
