Description

A touch screen panel {touch screen panel}

The present invention relates to a touch screen panel. More particularly, the present invention relates to a touch screen panel, and more particularly, to a touch screen panel in which a shielding portion for enclosing the electrode pad is formed so that electrode pads of a metal electrode layer connected to a first sensing electrode and a second sensing electrode of a transparent electrode layer are not exposed to the outside, The present invention relates to a touch screen panel capable of preventing electrode pads from being corroded.

With the development of computer technology, computer-based systems for various purposes are being developed and there is a growing demand for cleanliness, speed and convenience in using such systems.

In addition, there is a growing need for an input device capable of easily operating a device in a miniaturized and mobile computer or a multimedia device, and an input device using a conventional keyboard or a mouse is limited in terms of movement and use, A touch screen panel is used as an input device that can be directly input by a hand or a pen.

Such a touch screen panel is an input device for inputting a user's command by selecting an instruction content displayed on a screen of a video display device or the like as a human hand or an object, and has recently been applied to various information processing devices. Such a touch screen panel is simple in operation, has little malfunction, can input information without any other input device, and is manufactured in an integrated manner with an image display device to enhance the portability of the product.

The touch screen panel is classified into a resistive type, a capacitive type, a surface ultrasonic type, and an infrared type depending on the method of sensing the contact portion, and a resistive type and a capacitive type are mainly used.

The resistance film method is a structure in which two sheets of substrates on which transparent electrodes are coated are bonded together. When the upper and lower electrode layers come into contact with each other by applying pressure with a finger or a pen, an electrical signal is generated to recognize the position. In the case of such a resistive film method, the price is low, the accuracy is high, and it is advantageous for miniaturization, but it is difficult to manufacture robustly because the touch is recognized by physically contacting two substrates.

On the other hand, the electrostatic capacitance type uses a transparent substrate coated with a thin conductive material. When a certain amount of current flows on the surface of the transparent substrate and a user touches the surface of the coated transparent substrate, a certain amount of current is absorbed And recognizes the changed portion of the amount of current on the contact surface, thereby confirming the touched portion.

In order to accurately determine the contact position on the contact surface, the touch screen panel has a transparent electrode layer formed of a first sensing cell and a second sensing cell on a transparent substrate for recognizing the X-axis coordinate and the Y-axis coordinate. This will be described with reference to Fig.

1 is a schematic view of a transparent substrate of a conventional touch screen panel. 1, a first sensing electrode 10 including a plurality of first sensing cells 12 arranged in a row in the X-axis direction of the transparent substrate 1 is formed, A second sensing electrode 20 including a plurality of second sensing cells 22 arranged in a line in the Y-axis direction of the transparent substrate 1 is formed so as not to overlap the first sensing electrode 12.

At this time, the first sensing cell 12 is formed with a connection pattern 14 for electrically connecting two neighboring first sensing cells 12, and the first sensing cell 12 and the connection pattern 14 Are arranged in a plurality alternately.

A second sensing cell 22 is formed on the transparent substrate so as not to overlap with the first sensing cell 12, and the second sensing cell 22 includes two adjacent sensing cells 22, A bridge pattern 24 for electrically connecting the electrodes 22 is formed. At this time, the bridge pattern 24 connects the two second sensing cells 22 on the insulation pattern 30 so as to cross the connection pattern 14 without contacting the connection pattern 14.

The first sensing cell 12 and the second sensing cell 22 are formed in a rhombic shape except for forming the both ends of the first sensing cell 12 and the second sensing cell 22, And the second sensing electrode 20 including the plurality of second sensing cells 22 are connected to the first wiring portion 40 and the second wiring portion 50, respectively.

The second wiring part 50 connected to the first wiring part 40 and the second sensing electrode 20 connected to the first sensing electrode 10 is formed along the edge of the transparent substrate, The wiring portion 40 and the second wiring portion 50 are connected to the electrode pad 60 which is gathered at one side of the transparent substrate and is electrically connected to the flexible printed circuit board (FPCB) 70. In particular, the electrode pad 60 including the first wiring portion 40 and the second wiring portion 50 is made of a single metal such as Al, Cu, Mo, Ni, Ag, or Pd, or an alloy thereof.

However, in the conventional touch screen panel having the above-described structure, the electrode pad 60 connected to the flexible printed circuit board 70 is exposed to the outside, which may easily corrode.

Particularly, after the touch screen panel is manufactured, various tests are performed to test the reliability of the product. For example, when the user's sweat is sprayed on the touch screen panel to create an environment in which the user touches the touch screen panel Inspection will be carried out.

At this time, since the brine contains a large amount of chlorine (Cl) component, when the electrode pad 60 made of metal is exposed to the chlorine component, the electrode pad 60 is corroded and the electrode pad 60 ) May degrade the performance of the touch screen panel or cause the incapability of operation, making it difficult to pass the reliability test.
