Description

A touch screen panel {TOUCH SCREEN PANEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch screen panel, and more particularly, to a touch screen panel for a display device capable of reducing noise induced in a touch screen by a driving voltage of the display device.

In recent years, display devices such as liquid crystal displays (LCDs), electroluminescent displays (ELwctroluminescent displays), and plasma display panels have attracted attention because of their high response speed, low power consumption, . Such display devices have been used in a variety of electronic products such as televisions, computer monitors, notebook computers, mobile phones (mobiLw phones), display parts of refrigerators, personal digital assistants, and automated teller machines. Generally, these display devices constitute an interface with a user by using various input devices such as a keyboard, a mouse, and a digitizer.

However, the use of a separate input device such as a keyboard and a mouse has a problem in that it requires the user to learn how to use the device and occupies a space, thereby inconveniencing the user. 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 the 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. .

For example, the area of the driving electrode patterns 20 occupies about 70% to 95% of the total area of the touch screen panel, and the sensing electrode patterns 30 occupy 10% to 40% .

However, if the area of the driving electrode patterns 20 is increased, the noise components directly induced in the sensing electrode patterns 30 can be reduced.

Therefore, although the noise component directly induced in the sensing electrode patterns 30 can be reduced in the touch screen panel according to the related art, the noise components induced in the driving electrode patterns 20 can be detected by the sensing electrode patterns 30, Thereby deteriorating the touch performance.
