A display device includes a substrate, first electrodes, lines, pixel electrodes, a display functional layer, a common electrode, second electrodes, and a controller. The first electrodes are opposed to the second electrodes with a space therebetween, and an insulating layer is provided between the common electrode and the first and second electrodes. During the display periods, in response to a control signal from the controller, the pixel electrodes are supplied with a pixel signal through the lines, and the common electrode is supplied with a common signal. During the sensing period, in response to the control signal from the controller, the lines are supplied with a first drive signal to generate a magnetic field. The first electrodes are supplied with a second drive signal to generate electrostatic capacitance between themselves and the second electrodes in response to the control signal from the controller, synchronously or asynchronously with the display periods.

Technologies for detecting touch events on, or hover events above, a surface of an electronic device using radar units instead of integrated capacitive touch sensing technologies, are described. An electronic device includes a display located along a first plane. The electronic further includes a first radar unit coupled to the display. The first radar unit is oriented and comprises a first field-of-view (FoV) along a portion of the first plane. The electronic device further includes a processor coupled to the first radar unit. From the first radar unit, the processor receives first data that indicates a first object detection corresponding to a first location. The processor further determines, using the first data, a touch event associated with the display.
