Description

Take voltage gradient as the electronic pen of thickness

Technical field:

The utility model relates to electronic pen technology field, and refering in particular to voltage gradient is the electronic pen of thickness.

Background technology:

Electronic pen is mainly used in panel computer, mobile phone or has the display screen of touch controllable function, play and write and touch-control effect, at present, the electronic pen on market is all the electronic pen of pressure transducer or magnetic field induction, when pressure transducer electronic pen uses, nib accuracy is low, can not separate thickness well, can produce misoperation, also to adjust the induction gap of pen and display screen, use very inconvenient, with the electromagnetism bar then expensive price of magnetic field induction, and assembling and calibration are not easily.

Utility model content:

The purpose of this utility model is for the deficiencies in the prior art, and to provide with voltage gradient be the electronic pen of thickness, and utilize gradient to change, thickness is clearly demarcated, and is more suitable for the application being handwritten in panel computer.

For achieving the above object, the utility model adopts following technical scheme, and it comprises handwriting, nib, and handwriting is provided with nib, and nib is provided with solenoid, and handwriting is made up of radio-frequency unit, shaping circuit, high-voltage oscillation circuit.

The frequency of solenoid is that 100M hertz is to 500M hertz.

The utility model beneficial effect is: handwriting is provided with nib, and nib is provided with solenoid, and handwriting is made up of radio-frequency unit, shaping circuit, high-voltage oscillation circuit, utilizes gradient to change, and thickness is clearly demarcated, and is more suitable for the application being handwritten in panel computer.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model.

Fig. 2 is written using state one schematic diagram of the present utility model.

Fig. 3 is written using state two schematic diagram of the present utility model.

Fig. 4 is inner structure schematic diagram of the present utility model.

Embodiment:

See shown in Fig. 1 to Fig. 4: it comprises 1, take voltage gradient as the electronic pen of thickness, it comprises handwriting 1, nib 2, and handwriting 1 is provided with nib 2, and nib 2 is provided with solenoid 3, and handwriting 1 is made up of radio-frequency unit 11, shaping circuit 12, high-voltage oscillation circuit 13.

The frequency of solenoid 3 is that 100M hertz is to 500M hertz.

Shown in Fig. 2: during θ=90 ° voltage radiation to the integration of screen be a, Fig. 3 when an angle of inclination is, it is wide that b is that voltage radiation arrives the gradient of screen, is also equal to the display width of screen.

Pen to be write in electrical screen as shown in Figure 2, and pen to be write in electrical screen as shown in Figure 2, and be thin stroke, Fig. 3 is thick stroke, and in Fig. 2, the magnetic strength width of a is less than b magnetic strength width, and such Fig. 2 is thin stroke, and Fig. 3 is just thick stroke.

The above is only preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
