Abstract

The invention provides a capacitance type touch wire structure and a capacitance type touch panel.The capacitance type touch wire structure is characterized by comprising a glass substrate, a silicon dioxide film layer attached to a plate face of the glass substrate, and a metal lead attached to the silicon dioxide film layer and used for being electrically connected with an ITO thin film conductor layer, the metal lead comprises a connection transition layer, a conductive layer and an oxidation protection layer which are sequentially attached and stacked, the conductive layer is used for being electrically connected with the ITO thin film conductor layer, the oxidation protection layer is used for preventing the conductive layer from oxidation, the connection transition layer is connected and attached to the silicon dioxide film layer, the conductive layer is made from copper, and the connection transition layer is made from molybdenum or molybdenum and nickel alloy.Through the conductive layer made from copper, the wire resistance of the metal lead is reduced; the silicon dioxide film layer and the connection transition layer are well attached together, so the metal lead is prevented from being disengaged from the silicon dioxide film layer.

Description

technical field [0001] The invention belongs to the field of touch control, and in particular relates to a capacitive touch wire structure and a capacitive touch panel. Background technique [0002] The realization principle of the capacitive touch panel mainly utilizes the ITO (indium tin oxide) thin film conductor layer on the glass substrate, wherein the ITO thin film conductor layer has an ITO pattern area, and the ITO pattern area includes the electrode matrix of the X axis and the Y axis, The X-axis and Y-axis electrode matrices are coupled to each other to form a mutual capacitance. The drive controller TX and the signal receiver RX are respectively connected to the X-axis and Y-axis of the electrode matrix through metal leads. The drive controller TX sends out an excitation signal and transmits it through the metal leads. to the ITO pattern area. [0003] The capacitance sensing components of the capacitive touch panel are sensor electrodes and Y-axis longitudinal e...
