    Abstract: The present disclosure relates to a display driver integrated circuit and a display device. An example of the display driver integrated circuit includes a source driver and a timing controller. The source driver is configured to output a data voltage based on an image data to a first source line and a second source line. The timing controller is configured to receive first data and second data sequentially input to a first source channel that corresponds to the first source line, receive third data and fourth data sequentially input to a second source channel that corresponds to the second source line, perform an operation on the first data and the second data to generate a first change value, perform an operation on the third data and the fourth data to generate a second change value, and based on the first change value and the second change value, determine whether to toggle an output enable signal on an output of the second data in the first source line and an output of the fourth data in the second source line.
