1. A touch display having advanced-fringe-field-switching liquid crystal structure, including a pixel cell and a multiplexer circuit for providing a display function and a touch detection function, said pixel cell comprising:
a first substrate; a counter electrode located on said first substrate; a counter electrode connection line coupled electrically with said counter electrode; an insulation layer located on said counter electrode; a thin film transistor located on said insulation layer and having a gate, a source, and a drain; a pixel electrode located on said insulation layer and coupled electrically with said drain; a gate connection line coupled electrically with said drain; a source connection line coupled electrically with said source; and a liquid crystal layer located on said thin film transistor, on said pixel electrode, and on said insulation layer; and said multiplexer circuit comprising: a first multiplexer having a first contact, a second contact, and a third contact, wherein, said first contact is coupled with said source connection line, said second contact is coupled with a source driver unit, said third contact is coupled with a touch control unit, said first contact is coupled electrically with said second contact during a display period, and said first contact is coupled electrically with said third contact during a touch detection period; and a second multiplexer having a fourth contact, a fifth contact, and a sixth contact, wherein, said fourth contact is coupled with said counter electrode connection line, said fifth contact is coupled with a common voltage, said sixth contact is coupled with said touch control unit, said fourth contact is coupled electrically with said fifth contact during said display period, and said fourth contact is coupled electrically with said sixth contact during said touch detection period |
