The principle and application of stylus pen.

The capacitive pen is an auxiliary device that uses conductive materials to simulate human body to complete human-computer dialogue. Now the capacitive pen is no longer just a simple replacement for finger control functions, such as note taking, painting creation, art design, etc. At present, there are two kinds of active capacitance pens and passive capacitance pens on the market, so how to choose and buy capacitance pens? Which brand is better? How to use the capacitance pen? Next, the editor will introduce the relevant contents of capacitive pen in detail. Let's have a look at the knowledge encyclopedia of capacitive pen.

Introduction to capacitance pen
What is capacitance pen
Capacitive pen, as its name implies, is a touch pen for capacitive screen. It replaces the finger to directly touch the screen, and is mainly used in electronic devices such as capacitive screen mobile phones, tablet computers, touch notebooks, etc.
Working principle of capacitance pen

Capacitive pen is a pen made of conductive materials with conductive properties, which is used to touch the capacitive screen to complete the man-machine dialogue operation. Capacitive pen is an auxiliary device that uses conductive materials to simulate human body (usually fingers) to complete human-computer dialogue.

What is the capacitance pen for
The capacitive pen is used to touch mobile phones, computers and other electronic devices with capacitive touch screen. With the development of APP, capacitive pen is no longer a simple replacement for finger manipulation. More and more professionals have used active capacitive pen to work on mobile devices, such as note taking, drawing creation, document standards, etc. 

Is it necessary to buy a capacitance pen? If you need to write notes, draw or process documents with a tablet for a long time, you can edit and modify the text content very flexibly by using a stylus. When browsing the web page and swiping the video, using a stylus is also more convenient than clicking directly with your finger, which can significantly improve the user's convenience of using the tablet.

Which is better, capacitive pen or stylus
Which is better, capacitive pen or touch pen, and which pen to use for writing and painting mainly depends on the product selected. Different screens are suitable for different pens:

1. The stylus is a small pen-shaped tool used to input instructions to the computer screen and other devices with touch screen. Users can click the stylus on the touch screen to select files or paintings. The stylus is mainly applicable to the resistance screen.

2. The capacitive pen is made by using the characteristics of connecting the pen with the screen and conducting electricity, which is a physical principle. The pen head of the capacitive pen has static electricity, and the capacitive screen itself has the technical characteristics of inductive static electricity, so the capacitive pen is applicable to the capacitive screen.

Tip: Today's tablets, mobile phones and other devices basically use capacitive screens, so most of them use capacitive pens now.

Difference between active and passive capacitance pen
1. Different principles
Passive capacitive pen: The pen tip has enough touch area to absorb enough electrical signals, simulate the finger, and transmit this electrical signal to the hand through the conductive pen.

Active capacitance pen: A circuit like a pump actively draws more current, requiring batteries (whether rechargeable or standard replaceable).

2. Different precision
The tip of the active capacitance pen is thinner than that of the passive capacitance pen, so the accuracy of the active capacitance pen is higher than that of the passive capacitance pen. However, the active capacitance pen can not be used when the power of the active capacitance pen is zero.

3. Different tip diameters
Passive capacitance pen: the diameter of the pen tip exceeds 6 mm.
Active capacitance pen: the diameter of the pen tip is less than or equal to 3mm.

4. Different prices
The active capacitance pen usually has more internal chips than the passive capacitance pen, and the structure is more complex, so the price is usually more expensive. The passive capacitance pen can be bought for a few dollars, while the active capacitance pen costs tens of dollars.

The above is the difference between passive pen and active pen. Have you learned how to distinguish?
