Abstract
A display driving device supporting a low power mode according to an aspect of the present disclosure that is capable of minimizing power consumption when driving in the low power mode includes a plurality of output buffers connected to data lines to precharge the data lines with a first data signal corresponding to a black image when a precharge horizontal line is driven in a display panel including a first region where a standby image is displayed and the second region where the black image is displayed, the precharge horizontal line being included in the second region, and a gamma voltage generator connected to the data lines to output the first data signal to the data lines when other horizontal lines other than the precharge horizontal line in the second region are driven.
