Data driving device and display device including same

Abstract

A data driving device for driving a display panel includes a source data latch configured to latch image data and to output first data, a level shifter configured to receive the first data from the source data latch and to convert a level of the first data to generate second data, a decoder configured to separate the second data transmitted from the level shifter into upper bits and lower bits, a gamma block configured to generate gray scale data, and a source amplifier configured to amplify data output from the decoder and to output the amplified data to the display panel, wherein the decoder includes a data masking combination logic configured to control the lower bits.
