1. A device for driving data, the device comprising:
a plurality of channel amplifiers, each arranged in a channel; and
a controlling circuit configured to:
sequentially receive amplifier configuration data and image data for a horizontal line H+1 (H being a natural number) from a data processing device through a first signal line connected with the data processing device, and
determine, according to the amplifier configuration data, activation or deactivation of a second channel amplifier, among a first channel amplifier for outputting a data voltage corresponding to pixel data of a first channel and the second channel amplifier for outputting a data voltage corresponding to pixel data of a second channel, which is adjacent to the first channel during a horizontal driving period for the image data of the horizontal line H+1, wherein
the amplifier configuration data and the image data for the horizontal line H+1 are sequentially transmitted from the data processing device through the first signal line connected with the data processing device.
