Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1, an embodiment of the present invention provides a touch stylus pen, including: a penholder 3, a capacitance pen point 4 and an electromagnetic pen point 1; the pen holder 3 is made of a conductive material, and an electromagnetic induction circuit 2 is arranged inside the pen holder 3 and connected with the electromagnetic pen point 1; the capacitance pen point 4 and the electromagnetic pen point 1 are respectively arranged at two ends of the pen holder 3. The capacitive tip 4 is made of a flexible conductive material, such as conductive rubber, and has a hemispherical shape, and preferably, the diameter of the capacitive tip 4 is greater than 5 mm. The electromagnetic pen tip 1 is made of a non-conductive material.

As shown in fig. 2, the electromagnetic pen tip 1 and the electromagnetic induction circuit 2 constitute an electromagnetic input component of the touch pen, and when the electromagnetic pen tip 1 is used to operate on the electromagnetic screen 5, the electromagnetic induction circuit 2 connected to the electromagnetic pen tip 1 and the electromagnetic screen 5 generate electromagnetic induction and generate an induction signal, and the touch position coordinate of the electromagnetic pen tip 1 on the electromagnetic screen 5 is obtained by performing calculation according to the generated induction signal. At this moment, the electromagnetic pen point 1 is continuously moved on the electromagnetic screen 5 without lifting the pen, and the position coordinate of the movement of the electromagnetic pen point 1 can be continuously obtained according to the induction signal continuously generated by the electromagnetic induction circuit 2 in the pen, so that the movement track 6 of the electromagnetic pen point 1 is obtained, and the touch operation on the electromagnetic screen is completed. The electromagnetic induction circuit 4 may be a simple LC resonant circuit, or may be a circuit composed of a chip having both an electromagnetic induction function and a data processing function.

As shown in fig. 3, since the capacitive pen tip 4 is conductive, when the capacitive pen tip 4 is used to operate on the capacitive screen 7, a capacitive coupling effect is caused between the touch stylus and the capacitive screen, and as the capacitive pen tip 4 is pressed down, the contact area between the pen tip and the capacitive screen increases, the coupling capacitance changes, and the touch position coordinates are located by detecting the change in the coupling capacitance. At this time, the capacitive pen point 4 is kept in contact with the capacitive screen 7 without lifting the pen, and the capacitive pen point 4 is continuously moved on the capacitive screen 7, so that the touch position coordinates can be continuously obtained, a writing track 8 is formed, and the touch operation on the capacitive screen is completed.

Under the environment that capacitive touch and electromagnetic touch are combined, namely, when the touch screen can receive capacitive signals and electromagnetic signals, a user can select different pen points to perform input operation according to different requirements. For example: when a touch stylus is used for writing, it is preferable to use an electromagnetic pen tip for operation and to locate the touch position based on the electromagnetic signal. When the touch stylus pen is used for clicking operation, the capacitive pen tip is preferably used for operation because the capacitive pen tip is thick, and the touch position is located according to the capacitive signal.
