Driver integrated circuit and display device including the same

A display device comprising:

• a display panel including a plurality of pixels, the pixels being charged to a data voltage for displaying an input image in a display drive operation, electrical characteristics of the pixels being sensed in a sensing drive operation;
• and
• a driver integrated circuit configured to generate the data voltage in the display drive operation and sense the electrical characteristics of the pixels in the sensing drive operation, the driver integrated circuit including:
• a data voltage generator including a digital-to-analog converter converting a digital signal into an analog signal, the data voltage generator configured to generate the data voltage in the display drive operation and apply the data voltage to pixels of the display panel,
• a sensor connected to a sensing channel connected to the pixels of the display panel, the sensor configured to share the digital-to-analog converter with the data voltage generator, convert an analog sensing voltage from the sensing channel, which indicates electrical characteristics of the pixels, into digital sensing data in the sensing drive operation, and output the digital sensing data, and
• switching elements configured to selectively switch between the display drive operation and the sensing drive operation.
