The principle of electromagnetic induction of pen tablets, what is the electromagnetic induction of

The principle of electromagnetic induction is completely completed by electromagnetic induction in the positioning of the cursor and the movement of Wacom Intuos 5 passes. In the board of the pen tablet, there is a circuit board, on which there are horizontal and vertical balanced lines, the pen tablet is cut into a certain number of squares, the top of the board produces a balanced criss-cross magnetic field, when the pen tip moves on the pen tablet, the magnetic field is cut, so as to generate an electrical signal, through multi-point positioning, the pen tablet chip can accurately determine the position of the pen tip of the pen tablet. Therefore, the pen does not need to touch the tablet to move during the movement of the tablet cursor, and the sensing height is generally 15 mm.

There is a certain difference between the principle of the pen tablet of active wireless and that of passive wireless, the pen itself with a battery can release a certain magnetic field, while the pen without a battery is completed by reflecting the magnetic field generated by the pen tablet. The pressure inductance is generated by the pressure resistance in the pen, which is fed back to the tablet via a magnetic field signal.

Electromagnetic induction works by inducing the position of the pen tip with a coil by forming an electromagnetic field within a certain space range after the wiring circuit under the pen tablet is energized.

The tablet is used with a pen and shortcut keys, which cannot be operated with a finger.

iPads, other tablets, and now smartphones can be touchscreened, or finger-to-finger, because they use capacitive touchscreen technology, which uses the body's current sensing to work.

Electromagnetic pressure-sensitive original defense car body is the world's most accurate and natural handwriting digital realization of the technical solution, and it is also a very small number of enterprises that can produce and manufacture this high-tech handwriting digital product.

Youji's pressure pen uses active wireless technology, and its advantages are:

a, the pen has a battery and has energy, in the design can be for the energy requirements of the board is low, the pen needs a sail and the strength of the magnetic field obtained from the board is also low, as far as possible to reduce the impact of magnetic radiation on people's bodies. On the contrary, if there is no battery in the pen, the energy required for the board is large, the power consumption of the board is large, and the magnetic field generated is also large.

B. Because the pen and the plate have energy, the board and the pen are more comfortable in the magnetic field interaction and the deployment of anti-interference, which saves a lot of auxiliary circuit design, and fundamentally reduces the production cost from the technical level, which is also the core advantage of creating the best cost performance of the friendly base position board.

C, the pen using a AAA (No. 7) battery, its effective working time in the painting series is 4000 hours, the painting is 5000 hours, and the pen is designed with an automatic sleep function, that is, after a certain period of time is not used, it will automatically power off, and it can be activated to work after clicking, 8 hours a day to use, the battery electricity of a pen equipped with a series of drawing is theoretically available for 625 days, that is, more than one and a half years, and there is a certain thickness and a certain amount of pen closer to people's traditional use habits, It tends to be more natural with the pen, so that you can swing freely.

The active wireless technology used in the pen can clearly feel the high sensing height of the pen and the plate in the actual use effect, and it is easier to reach the pressure sensitivity value of 1024 levels, as well as other important performances, such as: reading speed, sensing accuracy, sensing height, resolution, etc., and the power consumption of the board is low and the power consumption is low. Especially when used on the same fully charged laptop, it lasts more than twice as long as similar products.
