A display driver integrated circuit (IC) includes a data line driver that drives a first data line connected with a first pixel of a display in response to output image data, and a dithering circuit that receives a brightness value of the display, calculates a first reference grayscale value corresponding to the brightness value using a first group of threshold grayscale values, receives input image data with a first grayscale value, which corresponds to the first pixel, compares the first grayscale value and the first reference grayscale value, and generates the output image data having not the first grayscale value but an output grayscale value when the first grayscale value is smaller than the first reference grayscale value.

Display driver IC including dithering circuit capable of adaptively changing threshold grayscale value depending on display brightness value, device including the same, and method thereof

A semiconductor device is provided. The semiconductor device includes: an offset compensation circuit configured to obtain first data including first low-order bit data, second low-order bit data and high-order bit data, select two compensation values from among a plurality of compensation values based on the first low-order bit data, identify a final compensation value by interpolating the two compensation values based on the second low-order bit data, and compensate the final compensation value to generate second data; and a source driver configured to interpolate and output two gamma voltages from among a plurality of gamma voltages based on the second data.
