초록
Disclosed is a low power and high density source driver and a current driven active matrix organic electroluminescent device having the same, in which all elements operate at a normal voltage and all circuits of the source driver are shielded from a high voltage of a panel. The source driver includes: a shift register for generating an enable signal for storing data; a data latch circuit for storing digital data inputted from an exterior; a line latch circuit for sequentially storing the data in response to the enable signal and outputting the stored data in parallel at one time in response to a load signal; a current type digital-to-analog converter for converting the digital data outputted from the line latch circuit into an analog signal, the analog signal being outputted in a form of a current signal; and a high voltage shield circuit for transferring the output of the current digital-to-analog converter to source lines of an external panel and for shielding internal circuits from a high voltage of the panel. The shift register, the data latch circuit, the line latch circuit, the current type digital-to-analog converter and the high voltage shield circuit are driven at a normal voltage.
