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.

Abstract: A display device includes a display driving controller receiving input image data, a synchronization signal, and a voltage control signal, and generating image data based on the input image data and the synchronization signal, a display panel including pixels disposed on a display area and displaying an image on the display area based on the image data, and a touch sensor including sensing electrodes on a sensing area, and detecting a touch input generated in the sensing area by driving the sensing electrodes. The display driving controller generates a second level of the synchronization signal by changing a voltage level of the synchronization signal having a first level based on the voltage control signal, and provides the synchronization signal having the second level to the touch sensor. The touch sensor deactivates at least a partial area of the sensing area in response to the synchronization signal having the second level.
