Claim Text:
1. A touch display device having auxiliary capacitor, comprising: at least one touch operation area, each having two opposing substrates for providing at least one touch surface, wherein, a first electrode, a first conductive line coupled with said first electrode, a second electrode, a second conductive line coupled with said second electrode, and a display layer neighboring both said first electrode and said second electrode are located between said two opposing substrates; and said at least one touch surface covers at least one touch sensing element, said touch sensing element being selected from a group consisting of said first electrode, said second electrode, said first conductive line, and said second conductive line; a display driver unit for outputting at least one display driving voltage to said at least one touch operation area; a touch detection unit having at least one touch signal sensing port, wherein each of said at least one touch signal sensing port is coupled with one surface of said at least one touch surface or with two surfaces of said at least one touch surface; at least one auxiliary capacitor, each having two connection ends coupled respectively with said first conductive line and said second conductive line of one of said at least one touch operation area; and at least one switch element; wherein, each of said at least one display driving voltage is coupled to one of said at least one touch operation area via one of said at least one switch element, and when said touch detection unit performs a touch detection procedure, at least one of said at least one switch element will be switched off.
