The invention discloses a touch device and a touch
display device thereof. The touch device comprises a substrate and a circuit board; the substrate comprises a display area and a non-display area surrounding the display area, the first touch control
electrode wires are electrically connected with the touch control
driving circuit, the second touch control
electrode wires are electrically connected with the touch control
driving circuit, and at least one first touch control
electrode wire surrounding the non-display area is electrically connected with the
near field communication circuit; thesubstrate further comprises an antenna, the antenna surrounds the non-display area, and the antenna is electrically connected with the near-field communication circuit; and the antenna is electricallyconnected with at least one first touch electrode wire surrounding the non-display area, so that the same near-field communication
signal is transmitted between the antenna and the first touch electrode wire. According to the touch device and the touch
display device thereof disclosed by the invention, an NFC antenna function can be added while a
touch function is realized; the NFC antenna is produced without occupying extra procedures, and meanwhile, part of the touch electrode wires are multiplexed into the NFC antenna, so that the NFC antenna does not occupy an extra frame area, and implementation of a narrow frame is facilitated.
