What is the difference between capacitive screen and resistive screen in mobile phone touch screen?

Capacitive screen, electrostatic induction, requires the conductor to contact the screen to react, so it does not need to be very forceful, as long as the finger gently touches the screen, it can be recognized. Then, ordinary stylus can't be used for capacitive screens, and capacitive screens have special stylus, with electrostatic electricity.

The advantage of capacitive screen is that it is sensitive to sensitivity, supports multi-touch, and is more suitable for entertaining games. The disadvantage is that you can't pinpoint it, for example, when you want to click on a word or punctuation mark exactly. Resistance screen, pressure sensing, requires force to react, so some girls always feel that the resistance screen is not sensitive, in fact, because she did not press the screen hard, as long as the strength is appropriate, the resistance screen is also quite sensitive.

The advantage of resistive screens is that they can be precisely positioned, making them suitable for business applications such as documents. The disadvantage is that it does not support multi-touch, and the sensitivity is not as high as that of a capacitive screen.

The capacitive screen can achieve multi-touch, but it is easy to cause screen floating, that is, the recognition is inaccurate, and it can be identified directly with the finger belly, and the resistance screen can be recognized accurately, but it can only realize single-point touch Some resistors can also be multi-point, but at most it seems that it can only reach two points, and it must be touched with sharp objects to identify, and the cost of capacitance is higher than that of resistors.

The capacitive screen can be multi-touch, with fingers, and the resistive screen can only use fingernails, and it is not sensitive.

It's useless to copy those majors, so I'll tell you something amateurish.

The resistive screen is a soft screen and is operated by pressing. Capacitive screens are hard screens that operate by contact. The advantages and disadvantages are obvious.

The resistive screen is relatively laborious, and the capacitive screen is labor-saving, but it is much less labor-saving than traditional buttons.

The brightness of the resistive screen is relatively poor, and it may be difficult to see clearly under the sun, and the capacitive screen is basically none. This is speaking of the same power consumption. You can adjust the brightness.

The capacitive screen must be operated with a conductor such as a finger belly, and the resistive screen can be operated with anything and a glove in winter.

The accuracy of a good capacitive screen is not bad, but misoperation is still very common, after all, the area of the finger belly is still relatively large compared to the screen, and the habit is good. The poor accuracy of the capacitive screen is really miserable. The accuracy of the resistive screen is high, and there is generally a nail operation, and any other pen can be used.

Capacitive screens all support multi-point operation, resistive screens do not.

The mobile phone is still a capacitive screen, and it is more expensive. Mobile phone resistive screens are rare. The resistive screen poke is healthier, like Nintendo's DS is the resistive screen, and the experience is also very good.

The capacitive screen can be seen clearly in strong light.

Hello, capacitive screens and resistive screens work differently.

The working principle of a capacitive screen is:

It works by using the current induction of the human body. The capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are coated with a layer of ITO, the outermost layer is a thin layer of silica glass protective layer, the laminated ITO coating is used as the working surface, four electrodes are drawn out on the four corners, and the inner layer ITO is the shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance, which is a direct conductor for high-frequency currents, so the finger draws a small current from the contact point.

This current divides from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance of the finger to the four corners, and the controller derives the position of the touch point by accurately calculating the proportion of these four currents.

The working principle of the resistive screen is:

This touch screen is controlled using pressure sensitivity. The main part of the resistive touch screen is a resistive film screen that is very compatible with the surface of the display, which is a multi-layer composite film, which uses a layer of glass or hard plastic plate as the base layer, and the surface is coated with a transparent oxide metal (transparent conductive resistance) conductive layer, which is covered with a layer of outer surface hardening, smooth and anti-friction plastic layer, and its inner surface is also coated with a layer of coating, between which there are many small (less than 1 1000 inches) transparent isolation points to separate the two layers of conductive layer insulation. When the finger touches the screen, the two conductive layers are in contact at the touch point, and the resistance changes, generating signals in the x and y directions, and then sending them to the touch screen controller.

Distinguish between capacitive and resistive screens:

Capacitive screens: Gloved hands or hand-held objects (touch pens) that do not respond to the touch because of the addition of a more insulating medium. The main disadvantage of the capacitive screen is drift: when the ambient temperature and humidity change, and the ambient electric field changes, it will cause the drift of the capacitive screen, resulting in inaccuracy.

The resistive screen can be touched by any object and can be used to write and draw, which is its big advantage.

The upper resistor can be written with a pen, but the capacitor cannot be used, but there is a special brush like a brush. The resistance needs to be pressed, and when you press it, you can feel that the activity of the outer film is very unpleasant, and the capacitive finger can be put on it, especially when the capacitive screen is supported, the feeling is much stronger. Functionally, the capacitive screen supports multi-touch, but the resistive screen is not good (there is already a multi-point resistive screen, but it is still lying in the laboratory).

The congenital defect of the resistive screen in appearance makes the screen uneven, and the capacitive screen can be as flat as a mirror. Therefore, it is recommended to buy a mobile phone or a capacitive screen, which is indeed more comfortable to use than a resistive screen.

To give you the most simple and easy-to-understand answer, the resistive screen can be controlled with a fingernail or stylus, and the capacitive screen can only be controlled with a finger.

The biggest difference is that the resistive screen can be operated with nails, stylus, etc., while the capacitive screen can be operated with fingers.

Very simple! Capacitive screens are easier to use than resistive screens!

Capacitive touch screen is good.

The superiority of capacitive screen is mainly manifested in two aspects:

1. The capacitive screen touch sensitivity is high, and the user only needs to touch it lightly with his finger or conductive object on the surface of the screen, and the screen can respond immediately. Users who have used resistive screens know that when operating on resistive screens, there is often no response due to insufficient click force, and this phenomenon can be effectively avoided on capacitive screens. Users who are accustomed to capacitive screens and then use resistive screens in turn are often "crazy".

Second, the capacitive screen is easy to realize multi-touch, the working principle of the multi-touch screen is to divide many independent touch units on the conductive layer, and each unit is connected to the external circuit through independent leads. Since all touch units are arranged in a matrix pattern, the system reacts to the user's finger movements, regardless of which part of the user's finger touches. Multi-touch technology can be greatly facilitated in the actual use of the operation, such as zooming in and out when browsing**, and page zoom and zoom when web browsing.

It's very simple:

The resistive screen is resistive, that is, if you press the screen with your finger or other places to cause resistance, it will sense that you are touching**. The capacitive screen induces current, your fingers have static electricity, as long as you touch the screen lightly, he can sense it.

Most capacitive screens support multi-touch, while resistive screens do not. Capacitive screens are more advanced.

Sure capacitive screen A capacitor with your hand (where the flesh) is a little bit on the line The resistance should be very strong But the resistance is also good, just take anything and you can operate it If you have to buy a resistive screen, don't buy Nokia 5230 5800 It will really be a screen!
