[Previous Technology] [0002] The touch display device combines touch technology and display technology, and is generally applied to electronic products such as mobile phones, media players, navigation systems, and digital cameras, and is used for input and display. [0003] Generally, a touch display device is composed of a display device and a touch screen. Display devices such as liquid crystal displays » Touch screens can be classified into resistive, capacitive, infrared, and surface acoustic waves according to their principles. Among them, the common capacitive touch screen has a structure in which a plurality of transparent electrodes perpendicularly intersecting each other are disposed on the surface of the glass substrate or the plastic substrate, and the transparent electrodes are connected to the controller through the peripheral conductive lines. When the user touches the surface of the touch screen with a finger, the capacitance value between the electrodes at the touch position changes, and the capacitance change signals are transmitted to the controller through the peripheral conductive lines for calculation, thereby confirming The coordinates of the touch position. [0004] The surface of the touch screen can be divided into a border of "visible area" and "non-visible area", the size of which depends on the precision of the conductive line; the more precise the conductive line, the smaller the frame. At present, the conductive circuit manufacturing method of the touch screen is to directly print conductive ink on the substrate to form a conductive line by using screen printing. The screen printed carrier is a screen. The conductive line made by screen printing has a large line width and line spacing, so the conductive line will occupy a large area, so that 1〇12〇269ί single number A0101 Page 3 of 19 Page 1013208730-0 M439854 On the 101st.

In addition, the conductive wire is also made by using the silk screen printing brush, and there are often defects such as cracking E, cracking, sheep's flatness, or the shape of the wire in the shape of a gourd. [0005] In addition, there are also conventional techniques for depositing a metal layer and then etching the metal layer by laser to form a conductive line. However, if a conductive circuit is formed on a plastic substrate, since the plastic layer is not required to be deposited by using a special physical deposition device, the equipment cost is high and it is difficult to control the thickness and uniformity of the deposited metal film.

Further, the conductive layer is formed by screen printing a conductive paste on a peripheral region of the substrate. [0009] Further, the conductive paste is one of conductive silver glue, conductive copper glue and conductive graphite glue.
