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.

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 invention discloses a low power driving system and timing controller for a display apparatus. The low power driving system may include: a timing controller configured to divide a display pattern into a static pattern and a dynamic pattern based on a difference between previous line data and current line data, and transmit a packet into which one of first option information corresponding to the static pattern and second option information corresponding to the dynamic pattern is applied; and a source driver configured to receive the packet, and perform a low power mode corresponding to the static pattern according to the first option information or perform adaptive charge sharing corresponding to the dynamic pattern according to the second option information.
