Description

Conductive Touch Pen {Conductive Type Touch Pen}

The present invention relates to a conductive touch pen. More specifically, by making the point contact or the surface contact of the contact tip in contact with the touch screen, the contact area can be minimized, so that the outer diameter of the conductive touch pen can be made to the minimum size, and the slim movement is possible. The present invention relates to a conductive touch pen that can be easily inserted into and withdrawn from a communication terminal, and thus is easy to carry and use.

In general, a mobile phone, a notebook, a touch screen TV or a monitor, an ATM device using a touch sensor panel or a touch pad, a resistive touch pen that operates by applying pressure to the touch screen to operate the device, and a touch sensor panel Alternatively, a capacitive touch pen is mainly used in which a capacitive element is formed on the touch pad to recognize and operate a change in the magnetic field flowing between the capacitive elements.

However, the resistive touch pen is designed to be used with a load of about 280 gf to 300 gf, but the pressure applied to the touch screen varies according to various users, causing failure of the touch sensor, and In order to give elasticity, the thickness of the thin film or transparent plastic material is used, and ITO film is attached to the surface thereof, but there is a problem that the screen is not easily seen due to the occurrence of scratches inevitably during long time use.

On the other hand, unlike the resistive touch screen having a touch life of approximately 25 million times, the capacitive touch pen applies a force to the touch screen because the touch sensor reacts and operates even when it is close to the touch sensor panel. There is no need to use the material of the touch screen, tempered glass can be used, and a protective film such as an ITO film does not need to be constructed. In addition, since it is not a method of directly applying pressure, even when used for a long time, the possibility of scratches is very low, so that a clear image can always be displayed. In recent years, a capacitive touch pen is gradually used rather than a resistive touch pen. There is a trend.

However, the conventional capacitive touch screen sensor is not operated by the resistive type static pressure stylus pen, that is, the resistive type touch pen, and the user directly touches the capacitive touch screen. However, since the touch screen configured in the capacitive terminal and the folder, icon, and text are very small in size, they are very small to be used by the user's hand. Not only it is inconvenient to use, but also touch the other folders, icons, characters in close proximity to the error occurs, as well as having a problem that it is very difficult to directly enter many characters with your fingers.

Accordingly, in the capacitive touch screen, a conductive touch pen has been developed, which is a tool that allows a user to induce electrostatic induction into a capacitive element patterned on a touch sensor. The contact portion that is in contact with the touch sensor unit configured in the capacitive touch screen is made of conductive silicone rubber or by using a carbon-containing conductive fiber as a conductive touch pen to operate the touch sensor of the capacitive touch screen. .

However, in order to operate the touch sensor of the capacitive touch screen, the touch sensor is operated only when a certain contact area is in contact with the touch sensor.

In particular, as the technology of the conductive touch pen continues to develop, the contact area for the operation of the touch sensor is gradually decreasing. Accordingly, while the contact area between the conductive touch pen and the touch sensor is reduced, the effect of the touch can be obtained in the same way. A conductive touch pen is required.
