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: According to an embodiment, the representative brightness value of image data is determined through an analysis of the image data, the dimming value of a backlight is adjusted according to the representative brightness value, and the image data is converted so as to correspond to the adjusted dimming value such that pixels maintain original brightness. In order to simplify the image data conversion, a characteristic value may be generated according to the adjusted dimming value, and a gamma curve may be generated on the basis of the characteristic value, thereby converting the image data.
