Description
The present invention relates to a touch screen panel, and more particularly, to a touch screen panel having a touch electrode structure capable of reducing a bezel size.
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, which makes 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 or approximates a screen with a hand or a pen while viewing the display device.
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 resistive type, 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 the touch is sensed, an LC And an electromagnetic type in which a value is read and a touched portion is sensed. In addition, an optical method, an ultrasonic method, and the like are known.
Generally, these types of touch screen panels include a touch area for touch recognition, a routing interconnection area and a pad area formed outside the touch area to exchange signals with the touch electrodes formed in the touch area. In this specification, a region where a routing wiring region and a pad region are combined is defined as a bezel region. These bezel areas generally increase as the number of channels connecting the routing wires increases due to the large touch area.
Hereinafter, a conventional touch screen panel will be described with reference to FIGS. 1A to 1C.
1A is a plan view showing a conventional touch screen panel in which bar-shaped touch electrodes are formed on both sides of a transparent substrate, FIG. 1B is a cross-sectional view taken along line I-I 'of FIG. 1A, 1a taken along the line II-II '.

Therefore, in the touch screen panel according to the embodiment of the present invention, it is not necessary to form any of the first and second routing wirings RW1 and RW2 on the other side of the touch region.
In contrast, in the conventional touch screen panel, the first routing lines RW1 connected to the first touch electrodes Tx are formed on the right side of the touch area TA, Since the second routing interconnections RW2 connected to the electrodes Rx are formed on the lower side of the touch region TA and formed on at least two sides of the touch region TA, the first routing interconnections RW1 are formed The bezel area is increased.
Therefore, according to the touch screen panel according to the embodiment of the present invention, the bezel area can be reduced by the area where the first routing wirings RW1 are formed with respect to the touch screen panel of the related art.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. For example, in the description of the embodiment of the present invention, the case where the length of the first touch electrodes and the second touch electrodes and the angle with respect to the x axis direction are moved from one side of the touch region to the other side is described as an example, The present invention is not limited to this, and if the first touch electrodes and the second touch electrodes are formed so as to intersect with each other, they may be formed to be opposite to each other. Also, the numbers of the first and second touch electrodes, the first and second routing wires, the first and second routing pads described in the embodiments of the present invention are merely exemplary and the numbers may be adjusted It should be understood that it can be done. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
