A small amount of current is drawn away from the panel, so that the controller of the panel calculates the contacted position based on the ratio of the current being drawn away. With the trend of miniaturization of electronic devices, the size of the touch panel has also been reduced. Therefore, it is often necessary to use the stylus to accurately perform the operation, and currently the existing technologies, such as the CN2619304 and CN2577353 patents. And the US Patent No. 5,546,224 discloses a stylus suitable for use in a touch panel for user operation. The common features of the 'CN2619304 and CN2577353 patents are that the stylus has a casing, a pen tip disposed at the casing end, a coil and a battery disposed inside the casing, and a coil and a battery disposed on the casing. The connected switch is pressed against the touch panel through the pen tip, so that the touch panel receives the pressure signal of the stylus, and the battery can be electrically driven to generate an induced magnetic field by activating the switch. The domain touch field is used to analyze the function of the right button of the ancestor; and the stylus disclosed in the patent of the us546i2G4 patent has its - the stylus used to apply force to the touch panel, and the internal stylus of the stylus has - - the coil and - the second slap - the first slap and the second coil to keep the connection: when the stylus pressure control surface (four) is separated by the pen head and separated from each other, (10) into (four) sense as a command signal input branch; These special 峨 之 雏 主 主 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或 或. The general-purpose capacitive touch panel _ control pen is used as the medium for the current material on the control panel, so that the current of the 5 201007506 current is transmitted to the tip of the pen _ end by the stylus. The body and design of the fairy syllabus will be electrically conductive on the touch panel, so that the user can hold the glove or its pure edge, even if it is used, but if The person shouts the transmission, causing the touch panel to be unable to recognize the operation state of the stylus that will affect the current on the touch panel. The content of the invention is such that the above-mentioned lack is made to make the stylus touch the touch panel contact point. 'Maintaining the transmission of current to help the touch panel recognize the main purpose of the stylus'. The present invention proposes a stylus suitable for a capacitive _ control panel, which is hollow to form a body for accommodating space, and Provided in the coil of the accommodation ==== road and having a peak electrically connected to the coil at one end of the pen body - the salty vine conductive element is used to contact the touch panel, so that the coil borrows the current The circuit generates an induced electric field to cause the touch panel to transmit the position pointed by the stylus through the induced electric field. The panel achieves an advantageous effect of the present invention over the prior art in improving the accuracy of the touchpad recognition position of the stylus.
