Abstract

A driver integrated circuit and a display device including the same are disclosed. The driver integrated circuit includes a data voltage generator that includes a digital-to-analog converter converting a digital signal into an analog signal, generates an analog data voltage in a display drive operation, and applies the analog data voltage to pixels of a display panel, a sensor that is connected to a sensing channel connected to the pixels of the display panel, shares the digital-to-analog converter with the data voltage generator, converts an analog sensing voltage indicating electrical characteristics of the pixels input from the sensing channel into digital sensing data in a sensing drive operation, and outputs the digital sensing data, and switching elements selectively operating in the display drive operation and the sensing drive operation.
