Description

Touch screen panel {TOUCH SCREEN PANEL}

The present invention relates to a touch screen panel, and more particularly, to a touch screen panel capable of improving touch sensitivity.

Recently, 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 and communication devices. However, using the input device as described above causes inconvenience such as having to learn how to use and occupying space, and thus it is difficult to improve the quality of the product. Accordingly, the demand for an input device that is convenient, simple, and capable of reducing malfunctions is increasing day by day. In response to such a request, a touch screen panel in which a user directly touches or approaches a screen with a hand or a pen while looking at a display device to input information has been proposed.

The touch screen panel is a resistive film method that determines the touched position as a voltage gradient depending on the resistance in a state where a DC voltage is applied by forming a metal electrode on the upper or lower plate according to the method of detecting the touched part ( resistive type), a capacitive type that forms an equipotential on the conductive film and senses the position where the voltage change of the upper and lower plates according to the touch occurs to detect the touched part (capacitive type), LC that is induced when the electronic pen touches the conductive film It can be divided into an electromagnetic type that reads a value and senses a touched part, and in addition, an optical method, an ultrasonic method, and the like are known.

Among these touch sensing methods, in the resistive film method, when a touch is made on the upper substrate and a touch pressure is applied, the transparent conductive films of the upper and lower substrates are in mechanical contact. The touch position is detected by sensing the electric potential. This resistive film method has the advantage of being able to sense a relatively accurate touch position because mechanical contact is involved. When a digital converter (ADC, Analog Digital Converter) is absolutely necessary and the contact force is small, there is a problem in that it is difficult to detect the touch position.

In contrast, the capacitive method forms a matrix by intersecting X-axis electrode columns and Y-axis electrode columns, and when a touch is made at an arbitrary position on the matrix, the coordinates of the X and Y axes on the matrix in which the capacitance is changed. Since the touch position is detected by finding it, there is an advantage in that the touch position can be detected even when the contact force is small.

Hereinafter, a conventional capacitive touch screen panel will be described with reference to FIG. 1 . 1 is a plan view showing a conventional touch screen panel.
