Abstract
A touch and hover sensing device includes a sensing module, a hover sensing unit, a touch sensing unit, and a switching control unit switching between a hover mode and a touch mode. The sensing module includes a plurality of first electrostatic sensing elements and a plurality of second electrostatic sensing elements electrically insulated from each other and located on a surface of an insulating substrate. The plurality of first electrostatic sensing elements is spaced from each other and extends along a first direction, and the plurality of second electrostatic sensing elements is spaced from each other and extends along a second direction. Each first electrostatic sensing element and each second electrostatic sensing element includes a single walled carbon nanotube or few-walled carbon nanotube.
