Abstract
A display driver integrated circuit (IC) that stores an output mode of driving circuit control signal in a non-volatile memory and a method of outputting the driving circuit control signal, wherein the display drive IC fixes the driving circuit control signal values using fixation wire disposed on top layers of the display driver IC, and a method of manufacturing the display driver IC. The display driver IC includes a plurality of driving circuits, which operate a display panel; a driving circuit control signal output unit, which outputs a plurality of driving circuit control signal values, which control the driving circuits, received from an external device in a test mode, or outputs the plurality of driving circuit control signal values, which control the driving circuits that are internally set to a plurality of fixed values in a production mode; and a non-volatile memory, which stores a mode selection value indicating the test mode or the production mode, wherein the driving circuit control signal output unit operates in the test mode or the production mode in response to the mode selection value stored in the non-volatile memory. In the display drive IC, which stores an output mode of a driving circuit control signal in a non-volatile memory, and a method of outputting the driving circuit control signal, whether to fix a driving circuit control signal value or not can be changed after the display driver IC is assembled into a module.
