Description

A touch screen panel {Touch Screen Pannel}

The present invention relates to a touch screen panel.

2. Description of the Related Art In recent years, various input devices such as a keyboard, a mouse, a trackball, a joystick, and a digitizer have been used to configure an interface between a user and a home appliance or various information communication devices.

However, the use of the above-described input device has a drawback in that it is required to learn how to use it and occupies a space, thereby making it difficult to improve the completeness of the product. Therefore, there is a growing demand for an input device that is convenient and simple and can reduce malfunctions.

In accordance with such a demand, a touch screen panel has been proposed in which a user directly touches a screen with a hand or a pen to input information.

The touch screen panel is simple, has little malfunction, can be input without using a separate input device, and can be operated quickly and easily through the contents displayed on the screen. .

In the touch screen panel, a metal electrode is formed on a top plate or a bottom plate according to a method of detecting a touched portion, and a resistive film type in which a touched position is determined as a voltage gradient according to a resistance a capacitive type in which an equal potential is formed on a conductive film and a touched portion is sensed by detecting a position where a voltage change of the upper and lower plates due to a touch is sensed and an LC value And an electromagnetic type in which a touch is detected by sensing the touch portion. In addition, an optical method, an ultrasonic method, and the like are known.

Generally, a touch screen panel is manufactured by attaching a transparent electrode film having a transparent electrode on a surface thereof to a cover glass.

The transparent electrode film is manufactured by coating an electrode material, for example, ITO (Indium Tin Oxide) on the surface, and forming a sensing electrode circuit by an etching process.

However, in the conventional touch screen panel, the resistance of the ITO (Indium Tin Oxide) electrode is high in a screen of 13 inches or more, and it is difficult to realize a multi-touch reduction in the touch speed.

In addition, indium, which is a main material of indium tin oxide (ITO), is a rare element, which is in danger of depletion and is expensive, which increases manufacturing cost of a touch screen panel.

In particular, ITO (Indium Tin Oxide) electrodes on a 13 inch or larger touch screen panel have a problem of excessive power consumption due to high resistance.

In addition, a touch screen panel can be manufactured by forming AgNW (Silver Nano Wire) on the entire surface of a transparent material and forming a transparent electrode by etching or laser processing. When a transparent electrode is formed using AgNW (Silver Nano Wire) There is a problem that the touch speed is excellent but the transparency is low due to low resistance.

7, Korean Patent Laid-Open Publication No. 2014-0014843 discloses a method of forming a blackening material layer 120 on a substrate 110 and forming a blackening material layer on the blackening material layer 120 And a step of printing the metal electrode pattern 130 and exposing the transparent substrate with the metal electrode pattern 130 as an etching barrier.

A step of forming a blackening material layer 120 on the substrate 110 is performed. The blackening material layer 120 refers to a material of black metal oxide or metal nitride. For example, any one selected from the group consisting of CuO, CrO, FeO, Ni 2 O 3, and AlN can be applied, and a black-based material capable of suppressing the reflectivity of the metal electrode pattern 130 described later can be applied. The blackening material layer 120 may be deposited on the substrate 110 by various coating methods. For example, various methods such as sputtering and evaporation may be used to deposit the blackening material layer 120 on the substrate 110 .

Thereafter, a process of printing the metal electrode pattern 130 on the blackening material layer 120 may be performed. The metal electrode pattern 130 may be formed using any one of silver (Ag), copper (Cu), and aluminum (Al) However, it is possible to implement a pattern in the form of a mesh.

The metal electrode pattern 130 may be formed by a variety of pattern printing methods such as a deposition method using a mask, a printing method, and the like. Alternatively, a reverse offset printing method may be used to directly print the electrode pattern on the substrate, A film can be produced.

Thereafter, a high-temperature sintering process may be added to the printed electrode pattern 130. In this case, the temperature of the sintering process may be in the range of 80 to 300 ° C.

The sintering process functions to harden the electrode pattern 130 and improve adhesion between the electrode pattern 130 and the blackening material layer 120.

The blackening material layer 120 may be selectively etched so that the structure of the electrode pattern 130 to be laminated on the blackening material layer 120 may be realized. 110) region can be implemented. In this case, the electrode pattern 130 acts as an etching barrier so that the blackening material layer 120 on the lower surface is not etched.

The completed electrode pattern is formed with a metal electrode pattern 130 on the upper portion and a blackening pattern as an etched pattern of the blackening material layer 120 on the lower portion.

The electrode pattern having such a structure can solve the problem that the reflected visible light increases due to the light reflection characteristic of the metal electrode pattern 130 due to the presence of the blackening pattern having the rectangular cross section as described above, An advantage of improving the characteristics is realized.

However, there is a problem that the moire phenomenon due to the regularly arranged metal electrode patterns 130 can not be prevented.
