Xiao Bian always likes to draw on the iPad, but this does not mean that drawing on the iPad is better than drawing on paper. Drawing on the iPad is always better than drawing on paper, even if we hold a capacitive pen in our hand. Whether we write or draw on the screen, the lines drawn are very thick and the same thick. Note 2's stylus is much better than the capacitive stylus, and it is much more accurate than the capacitive stylus. Xiao Bian once thought about whether to use the Note2 stylus on the iPad? Of course, the result is no good. Everyone is also a capacitive screen. Why can Samsung's Note work, but not the iPad?

Note 2 The effect of the stylus is certainly related to the electromagnetic pen and the mobile phone itself. Different from ordinary mobile phones, Note 2 has an additional electromagnetic plate behind the LCD screen, which can sense the electromagnetic signals emitted by the electromagnetic pen. Ordinary mobile phones do not have such an electromagnetic board, so simply from the hardware, other products will not meet the conditions for the use of the electromagnetic pen, so it is normal that it cannot be used on the iPad.

When the electromagnetic pen is close to the screen, the electromagnetic plate will sense the electromagnetic signal sent by the pen, and then obtain the X and Y coordinates of the pen through some complicated calculations, so that the phone can know the position of the pen. In addition, since the electromagnetic plate is on the back of the LCD screen, the electromagnetic plate will not affect the display effect of the LCD screen.

The magic function of Note 2 is actually the technology of Wacom (a famous digital tablet company), and of course, the pressure sensing function of Wacom has also been integrated into this pen. Pressure sensing is also called pressure sensing. S Pen can sense the pressure of the pen touching the screen.

When the pen tip is stressed, the pressure will be transmitted to the pressure sensor through the pen core. The change of pressure will lead to the change of the electromagnetic signal sent by the electromagnetic pen. At this time, the mobile phone can sense the pressure. Just like holding a pencil to write, press hard, and the handwriting will become thicker, smaller, and thinner. So this pen is especially suitable for handwriting and painting.
