Abstract: A display device includes: a first sensor driver connected to a first sensor unit including a first-analog-front end, a first analog-to-digital converter, and a digital signal processor; and a second sensor driver connected to a second sensor unit including a second-analog-front end, and a second analog-to-digital converter. In a first mode, the first-analog-front end and the first analog-to-digital converter generate first sensing information for the first sensor unit, the second sensor driver does not operate, and the digital signal processor processes the first sensing information based on a first setting value for the first sensor unit. In a second mode, the first-analog-front end and the first analog-to-digital converter do not operate, the second-analog-front end and the second analog-to-digital converter generate second sensing information for the second sensor unit, and the digital signal processor processes the second sensing information based on a second setting value for the second sensor unit.
