Embodiment Construction
[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 As shown, the capacitive touch screen stylus includes a pen holder 1 and a pen head 2 . The penholder 1 is entirely or partially made of hard conductive material, such as conductive metal. The nib 2 is made of flexible conductive material, such as conductive rubber. The nib 2 is in the shape of an inverted cone, from thick to thin. The thick end of the nib 2 is directly connected to the pen holder 1, and the thin end of the nib 2 guides the writing position to ensure a more accurate writing position of the pen. The pen head 2 can also be connected with the pen holder 1 through a conductive material. The connection between the pen holder 1 and the pen head 2 and the contact between the hand and the pen holder 1 must have conductivity, that is, when the capacitive touch screen stylus is held in hand, t...

The invention provides a capacitance type touch screen writing pen which belongs to the computer peripheral input field. The pen includes a pen head made by flexible conducting material and a penholder made by hard conducting material whole or partly. When writing, touch area of the pen head and the capacitance touch screen increases gradually, the capacitance touch screen determines coordinates information of the pen according with touching area size for capturing charge change caused by the pen, and further determines position of the pen. When the pen is moved, stroke is formed. After the pen is took up, touch area of the pen head and the penholder decreases gradually even to zero, the capacitance touch screen loses coordinates information of the pen because of no-capturing charge change caused by the pen. The pen is located again for forming new stroke, the process is repeated for completing word input. The pen provided by the invention solves problem that the pen is used for inputting word on the capacitance touch screen smoothly, has simple structure and is convenient for operation.
Description
technical field [0001] The invention belongs to the input field of computer peripheral equipment, and relates to a stylus for writing on a capacitive touch screen and transmitting handwriting through the capacitive touch screen. Background technique [0002] Current capacitive touch screens only respond to the touch of conductive objects. The capacitive touch screen cannot respond to the contact of sharp objects, because the contact area between the sharp object and the capacitive touch screen is small, and the capacitive touch screen cannot produce a measurable change in charge. The tip of a general or general-purpose stylus is small, and the contact area with the capacitive touch screen is very small, so handwriting input on the capacitive touch screen cannot be realized. [0003] Fingers are conductive and have a sufficient contact area. It is easy to directly click on the capacitive touch screen or complete specific actions. However, when using fingers to perform handwr...
