Abstract:
A driver IC device includes a correction function having a unit-block setting unit for dividing pixels of a display panel into preset units so as to set the same as a plurality of unit-blocks; a correction route (LUT) setting unit for setting a LUT having a plurality of sub-regions arranged in the same form in response to an arrangement of the pixels included in the unit-blocks set through the unit-block setting unit; a storage unit for storing the LUT set through the LUT setting unit, and storing respective gain values and offset values for the plurality of unit-blocks set through the unit-block setting unit; a changing unit for changing an input value (input gray) inputted to the pixels of the display panel, by using the gain values and offset values stored in the storage unit; and a correction output unit for generating a correction output value (output gray) of the pixels in the unit-blocks of the display panel by using a change value obtained through the changing unit and a coordinate value of the LUT set through the LUT setting unit.
