Fixed Control Data Generation Circuit and Display Device Driving IC Having the Same

A display device driving circuit comprising:

• a fixed control data generation unit including a plurality of logic devices having at least one rows and at least one columns;
• a register unit receiving and storing fixed control data;
• and
• a logic circuit receiving a signal provided from the register unit as control data and generating a signal for driving a display device by performing a logic operation using the control data,
• wherein each of the plurality of logic devices is connected to one of a first voltage and a second voltage through a metal line and provides the connected voltage as the fixed control data to outside.

A fixed control data generation circuit comprising:

• a switching unit in a matrix form having at least one rows and at least one columns;
• a row decoder receiving a row address signal and driving the rows of the switching unit in response to the received row address signal;
• and
• a column decoder receiving a column address signal and driving the columns of the switching unit in response to the received column address signal,
• wherein each of a plurality of switches included in the switching, unit has a first electrode connected to one of a first voltage and a second voltage and provides a voltage connected to the first electrode in response to the row address signal as the fixed control data to outside.
