However, although the traditional stylus is operated with a resistive touch sulphur, there is no such thing as a capacitive touch panel. SUMMARY OF THE INVENTION The present invention provides a color control pen for conversion to a capacitive touch surface. The present invention further provides an electronic device that enables a __operation capacitor 5 200928883 V 26493 twf.doc/d type touch panel. The stylus of the present invention is used for operating a capacitive touch panel, and has a pen body and a head connected to the pen body. Both the pen and the pen are electrically conductive. The material of the tip is elastic and the appearance of the tip is deformed by external force. The electronic device of the present invention includes a device body and a stylus. The body of the skirt has a capacitive touch panel. The stylus has a body and a pair of heads that connect the pen body. Both the pen and the pen are electrically conductive. The material of the pen tip is elastic material' and the appearance of the pen tip is deformed when it contacts the capacitive touch panel. In an embodiment of the stylus and the electronic device, the material of the pen tip comprises a conductive rubber. In an embodiment of the stylus and the electronic device, the tip is solid. In an embodiment of the stylus and the electronic device, the pen tip is hollow and has a chamber and an elastic outer casing. In addition, the stylus may further include an elastic member disposed in the chamber of the pen tip. In addition, the elastic member may be a spring or a spring. In an embodiment of the stylus and the electronic device, the pen body is entirely made of a conductive material. In an embodiment of the stylus and the electronic device, the pen body includes an insulating body and a conductive layer covering the surface of the insulating body. In an embodiment of the electronic device, the capacitive touch panel is a capacitive capacitive touch panel or a resistive capacitive touch panel. In summary, the stylus of the present invention has electrical conductivity, and the tip of the stylus has elasticity. Therefore, the stylus of the present invention can increase the contact area with the capacitive touch panel to facilitate operation of the capacitive touch panel. In order to make the above and other features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are described in the accompanying drawings. Embodiments FIG. 1 is a schematic diagram of a stylus according to an embodiment of the present invention. Referring to FIG. 1, the stylus pen 1 of the present embodiment has a body 110 and a pen tip 120 connected to each other. Both the pen tip 120 and the pen body 110 are electrically conductive. The material of the tip 11〇 is elastic material. Therefore, the appearance of the pen tip 11〇 is deformed by an external force, and the appearance of the pen tip φ 120 is restored to the original state after the external force is removed. Therefore, the stylus pen 1 does not deform before contacting the capacitive touch panel (not shown), so that the pen tip 120 can maintain a pointed appearance to avoid obscuring the user's line of sight and causing the user to see clearly. The icon (ic〇n) on the capacitive touch panel. Moreover, after the pen tip 120 contacts the capacitive touch panel, the force exerted by the capacitive touch panel on the pen tip 120 deforms the pen tip 120 to increase the contact area with the capacitive touch panel, thereby increasing the capacitive performance of the stylus pen 100. The success rate of operation on the touch panel. In short, the contact area between the stylus 100 and the capacitive touch panel must reach a certain area, and the capacitive touch panel can respond. In other words, if the pointed conductive material of the paper clip contacts such a capacitive touch panel, the capacitive touch panel does not respond. In addition, when the stylus pen 100 leaves the capacitive touch panel, the appearance of the pen tip 120 is completely restored to ensure that the pen tip 12 is not deformed to avoid obscuring the user's line of sight. In this embodiment, the material of the pen tip 120 may be conductive rubber or other electrically conductive material that is deformable and reversible. In addition, the pen 12 can be solid. Alternatively, as shown in Fig. 2, the pen tip 120 may also have a face 7 V 26493 twf.doc/d 200928883 chamber 122 and an elastic outer casing 126, thereby increasing the degree to which the pen tip 12 is deformable. At the same time, an elastic member 124 may be disposed in the chamber 122 of the pen tip 120. The elastic member 124 may be a spring piece, a spring or other suitable elastic member. The elastic member 124 can increase the elastic restoring force of the pen tip 120 to ensure that the appearance of the pen tip returns to its original state after leaving the capacitive touch panel. Additionally, the pen body 110 can be made entirely of, for example, metal or other electrically conductive material. However, the pen body 110 can also be composed of an insulative housing (not shown) and a conductive layer (not shown) covering the surface of the insulative housing. The material of the insulating body is, for example, plastic or other insulating material, in particular, a lower cost insulating material can be selected. The material of the conductive layer may be metal or other suitable conductive material and may be applied to the surface of the insulative body by electroplating or other suitable means. 3 is a schematic diagram of an electronic device according to an embodiment of the invention.

Electronic device for controlling functions. The device body 210 has a capacitive touch panel 212. Since the stylus pen 10's pen tip 120 and the pen body 11 导电 are both electrically conductive, the electric charge carried by the user when the user holds the pen body 11 将 will be transmitted to the capacitive touch panel 212 via the pen body 110 and the pen tip 120. The electric field distribution on the capacitive touch panel 212 is changed to cause the capacitive touch panel 212 to react. In order to achieve the purpose of transferring electric charge, in the present invention, the definition of the conductivity of the pen tip 120 and the pen body 110 is that the pen tip 120 and the pen body 110 can provide a conductive path having a lower resistance value than the human body. 8 V 26493 twf.doc/d 200928883 In the electronic device 200 of the embodiment, since the appearance of the pen head 11 () can be deformed and restored to the original stylus 1 〇〇, the stylus 1 〇 () and the capacitance can be increased. The contact area of the touch panel 212 increases the operational success rate. In summary, the stylus of the present invention has the property of being deformed by force and returning to its original state without being subjected to force. Therefore, the stylus does not deform before contacting the capacitive touch panel to avoid obscuring the user's line of sight, and the stylus may deform when contacting the capacitive touch panel to increase the contact area, thereby making the capacitor The electric field of the touch panel can be significantly changed to improve the operational success rate of the electronic device using the touch pen.
