摘要： A display device is provided. The display device may include pixels arranged in rows and columns, gate drivers connected to the rows of the pixels through gate lines, source drivers connected to the columns of the pixels through source lines, and a timing controller configured to control the gate drivers and the source drivers. The source driver associated with the specific pixel among the source drives may first supply an overdrive voltage corresponding to a final overdrive value to a source line connected to the specific pixel and then supply a source line voltage corresponding to a current value of the specific pixel to the source line. The overdrive controller may change weight values of at least two overdrive values based on a position of the specific pixel and interpolate the at least two overdrive values.

摘要： Disclosed is a display driver integrated circuit (IC) which 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.
