Touch screen pen modeled after the human body contact screen, when the finger touch in the electronic screen, the human body electric field and touch screen surface formed a capacitance, the finger can suck away a small current. Touch screen pen is also this way, capacitance is a direct conductor, the current can flow from the four corners of the screen electrodes, the current flowing through these four electrodes and the distance between the tip of the pen can be realized by a precise calculation to arrive at the location of the touch point.
What are the quality features of the touch screen pen?

1, smooth writing, easy to use: many designers need to use a specialized writing tablet connected to the computer, the transfer of their drawings to the computer screen above, essential when the touch screen pen.

4, long time touch, do not harm the screen: the screen of electronic products is the core component, but also very easy to damage, so many people worry about the stylus will not damage the electronic screen. High-quality stylus pen with POM nibs, tough and durable, can write 10,000 meters continuously, 100,000 times the friction will not harm the electronic screen.

5, replaceable nibs, to ensure that the use of a long time: the nib of the stylus pen is an important part of the writing, high-quality stylus pen manufacturers configured with replaceable nibs, nibs wear-resistant, can be easily replaced. Want to remove the nib, you can rotate counterclockwise, want to install the nib, you can rotate clockwise, the nib is bad in time to replace it, very convenient.
