Moreover in touch control display panel, each signal wire only is connected with single touch-control electrode, to reduce the quantity of the touch-control electrode in the panel.Therefore, can avoid the too much too much stray capacitance that the touch-control electrode produced and the not good problem of touch-control sensing property of the touch control display panel that causes.

Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
