Description

TOUCH SCREEN PANEL AND DISPLAY DEVICE HAVING THE SAME

The present invention relates to a touch screen panel and a display device having the same, and more particularly, to a touch screen panel using a mesh pattern and a display device having the same.

A touch sensing device capable of recognizing a touch position through touch or proximity is an input device that is attached to a display device to provide an intuitive input method to a user, and is an input device such as a recent smart phone, a personal digital assistant (PDA), a navigation device, and the like. It is widely applied to various electronic devices. In particular, with the recent increase in demand for smart phones, interest in a touch screen panel capable of providing various input methods in a limited form factor is increasing day by day.

A touch screen panel applied to various display devices may be classified into a resistive type and a capacitive type according to a method of sensing a touch input. Among them, the capacitive method has a relatively long lifespan and has the advantage of being able to easily implement various input methods and gestures, so its application rate is increasing. In particular, the capacitive method is widely applied to devices such as smart phones because it is easier to implement a multi-touch interface compared to the resistive method.

The capacitive touch screen panel includes a plurality of electrodes having a certain pattern, and measures the change in capacitance with respect to a touch input using a self-capacitance type or a mutual-capacitance method. Then, the coordinates of the touch input can be calculated by using a known touch algorithm.

In a conventional touch screen panel, a touch electrode for recognizing a touch is usually formed of a transparent conductive material such as ITO (Indium Tin Oxide; Indium Tin Oxide).

However, in the case of ITO, there are problems in that indium, a raw material, is expensive as a rare earth metal, and supply and demand are not smooth due to a small amount of production. In contrast, the fine conductor wire formed of a highly conductive metal material has much superior electrical conductivity compared to ITO or conductive polymer, and has the advantage of smooth supply and demand. For this reason, research to form a touch electrode using a thin conductor wire is being conducted.

When the touch electrode is formed using the thin conductor wires, the thin conductor wires are configured like a mesh, and thus have a mesh shape. Such a mesh shape has a certain period and pattern. Since the touch screen panel is disposed on the upper part of the display, the mesh shape of the thin conductor wires having a predetermined period and pattern interferes with the periodic pattern of pixels or black matrix periodically arranged on the display panel to cause a moire phenomenon. There is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a touch screen panel capable of preventing a moiré phenomenon, which is an optical interference effect caused by overlapping two or more periodic patterns, and a display device having the same.

The touch screen panel of the present invention for achieving the above object includes a substrate; a first touch electrode arranged on the substrate in a first direction and formed of a plurality of first thin wires; and a second touch electrode arranged on the substrate in a second direction crossing the first direction to be electrically insulated from the first touch electrode and including a plurality of second thin wires, wherein the plurality of first thin wires A predetermined polygon is formed by overlapping the plurality of second thin lines.

The predetermined polygon in the above configuration is characterized in that it is a pentagon.

Also, the length of at least one of the thin wires constituting the pentagon may be different from the length of the other thin wires.

In addition, the first touch electrode includes seven hexagonal mesh patterns formed by the plurality of first thin wires, and one first hexagonal mesh pattern among the seven hexagonal mesh patterns has vertices located therein. The three first divided thin lines are combined to form three first pentagonal mesh patterns sharing one side with each other, and the remaining six second hexagonal mesh patterns share one side around the one hexagonal mesh pattern. a third hexagonal mesh pattern comprising six second thin lines connecting vertices disposed at positions corresponding to inner positions of each of the remaining six second hexagonal mesh patterns, and the second touch electrode comprises: Six third thin lines that start from a vertex of the third hexagonal mesh pattern and intersect one side of each of the second hexagonal mesh patterns may be included.

In addition, the first touch electrode includes seven hexagonal mesh patterns formed by the plurality of first thin wires, and the remaining six second hexagonal mesh patterns are formed around one first hexagonal mesh pattern among the seven hexagonal mesh patterns. The hexagonal mesh patterns are arranged around the one hexagonal mesh pattern to share one side with each other, and the second touch electrode has vertices disposed at positions corresponding to the inner positions of each of the remaining six second hexagonal mesh patterns. A third hexagonal mesh pattern composed of six connecting second thin lines, and three second divisions starting from a vertex positioned inside the third hexagonal mesh pattern and intersecting the second thin lines of the first hexagonal mesh pattern and six third thin lines that start from a vertex of the third hexagonal mesh pattern and intersect one side of each of the second hexagonal mesh patterns, wherein the first hexagonal mesh pattern and the second divided thin line The first pentagonal mesh pattern may be formed by bonding.

In addition, by overlapping the first and second hexagonal mesh patterns and the third hexagonal mesh pattern, the second hexagonal mesh pattern may form three second pentagonal mesh patterns.

In addition, the first pentagonal mesh pattern and the second pentagonal mesh pattern may be randomly arranged.

Also, the thin wires constituting the third hexagonal mesh pattern may be disposed outside the thin wires constituting the first hexagonal mesh pattern.

Also, the thin lines constituting the third hexagonal mesh pattern may be disposed to cross the thin lines of the second hexagonal mesh pattern connected to the first hexagonal mesh pattern.

A display device of the present invention for achieving the above object includes: a display panel for displaying an image on a display screen; and a touch screen coupled to correspond to the display panel.

In the above configuration, the display panel may be any one of a liquid crystal display panel, a plasma display panel, an electroluminescence display panel, and an electrophoretic display panel.

Also, the first contact point where the plurality of first thin wires meet and the second contact point where the plurality of second thin wires meet may be formed so as not to overlap each other.

In addition, the plurality of polygons formed by overlapping the first thin lines and the second thin lines may have fewer polygons than the polygons composed of the first thin lines of the first touch electrode or the polygons composed of the second thin lines of the second touch electrode. It may be a polygon with sides.

In addition, a plurality of divided fine lines may be further included in the polygonal interior of the first thin lines of the first touch electrode or the polygon of the second thin lines of the second touch electrode.

Also, the first touch electrode and the second touch electrode The polygonal mesh pattern having the smallest area among the polygonal mesh patterns formed by the overlap of , may be formed to have an area of 50%-100% of the polygonal mesh pattern having the largest area.

According to the touch screen panel according to the present invention, the random degree of the mesh pattern is increased by the combination of the first and second mesh patterns constituting the first touch electrode and the third mesh pattern constituting the second touch electrode. Therefore, it is possible to obtain the effect of reducing the moiré phenomenon due to the regular arrangement of the mesh pattern.

In addition, according to the display device including the touch screen panel according to the present invention, the opening formed by the first and second thin wires is formed by the combination of the first mesh pattern, the second mesh pattern, and the third mesh pattern.

Accordingly, it is possible to obtain an effect of preventing the line moiré phenomenon in the form of an optical band, which may occur when dense and small portions of the fine lines constituting the combined mesh pattern appear regularly.
