Image data driving apparatus and method of reducing peak current
A source driver includes a hold memory block, a pre-decoding block, a level shifting block and digital-to-analog (DAC) block. The hold memory block stores digital image data. The pre-decoding block generates a data code that includes at least one bit having a first logic level based on the digital image data and generates a plurality of enable signals based on the data code. The level shifting block performs level shifting of the data code based on the enable signals. The DAC block outputs a grayscale voltage that is selected based on the level shifted data code output from the level shifting block. A source driver module and a display device include a plurality of the source drivers.
