Embodiment Construction

[0055] The stylus according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] see figure 1 , the first embodiment of the present invention provides a stylus 100 for a touch screen. The stylus 100 includes a barrel 110 and a tip 120 disposed at one end of the barrel 110 . The tip 120 is flexible and conductive.

[0057]The function of the pen holder 110 of the stylus 100 of the present invention is mainly to provide a gripping part for the user to operate the pen head 120 . When the stylus 100 is a pen that relies on the conductivity of the human body to achieve touch operation, the pen holder 110 needs to have the function of transferring the electrostatic charge on the human hand to the pen head 120, that is to say, the pen holder 110 needs to be compatible with the pen head. 120 electrical connections. When the stylus 100 is not a pen that achieves touch operation by the conductivity of the ...

Abstract

The invention relates to a stylus. The stylus comprises a stylus holder and a nib, wherein the nib has flexibility and conductivity; and when in use, contact capacitance is generated between the nib and a touch screen. The stylus is characterized in that the nib consists of a plurality of carbon nano tubes.

Description

technical field [0001] The invention relates to a touch pen, in particular to a touch pen applied to a touch screen. Background technique [0002] In recent years, along with the high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, the number of electronic devices in which a light-transmitting touch panel is mounted on the front of a display device such as a liquid crystal is increasing. Users of such electronic devices use the touch screen to visually confirm the display content of the display device located on the back of the touch screen, while pressing the touch screen with a finger or a pen to perform operations. Thereby, various functions of the electronic device can be operated. [0003] According to different working principles and transmission media of touch screens, existing touch screens are divided into four types, namely resistive type, capacitive type, infrared type and surface acoustic wave typ...
