Is a capacitive screen stronger than a resistive screen?

Capacitive screens are more sensitive than resistive screens and are touch screens in the true sense.

The capacitive screen can be operated on the screen with fingers touch, gently swipe, in addition, the capacitive screen needs temperature sensing, that is to say, maybe the hand does not necessarily completely touch the mobile phone may be sensitive, and the feel will be much better.

The resistor screen operation needs to be forced. As for the sturdiness, don't worry, it's not soft, because the resistive screen is generally equipped with a stylus, which must need a certain hardness to support. If you can press it down, how much more powerful.

The principle is different, but it must be a better capacitive screen, and there should be no objection to this.

1. Resistive touch screen: The fundamental characteristics of the resistive screen determine that the top of the resistive screen is soft and needs to be able to press down. This makes the screen very susceptible to scratches.

Resistive screens require a protective film as well as comparatively more frequent calibration. On the plus side, resistive touchscreen devices that use a plastic layer are generally less vulnerable to damage and less likely to break.

2. Capacitive touch screen: glass can be used on the outer layer. Although it is not indestructible and has the potential to shatter under severe impact, the glass is better coped with everyday scratches and stains.

The screen used by the iPhone is the capacitive screen! I fell a few times, but nothing happened.

You can stick a film, you can also use a capacitive pen, the capacitive pen is made of conductive sponge, and the better ** is about 100-300rmb. I think it's better to touch with your hands, just don't push too hard.

Advantages of capacitive screens:

1. You can multi-touch, now the multi-touch capacitive screen used on IP can only achieve two-point simultaneous touch, and it will develop into three-point, four-point, and N-point in the future.

2. High positioning accuracy.

Disadvantages of capacitive screens:

1. The more important disadvantage of the capacitive screen is drift: when the ambient temperature and humidity change, and when the ambient electric field changes, it will cause the drift of the capacitive screen, resulting in inaccuracy. For example:

The temperature of the display rises after powering on, which can cause drift: the user will drift when touching the screen with the other hand or side of the body close to the monitor; Larger objects near the capacitive touch screen will drift after moving, and if someone comes around when you touch it, it will also cause drifting; The reason for the drift of the capacitive screen is a congenital deficiency of technology, although the environmental electric potential surface (including the user's body) is far away from the capacitive touch screen, it is much larger than the finger area, and they directly affect the determination of the touch position.

2. The capacitive screen can only sense the touch of objects with bioelectricity, such as fingers, and the impact of the surrounding environment on him is fatal, if your fingers have hand sweat, the capacitive screen may no longer be able to provide you with services, if you are in a bathroom full of water vapor, or a sauna, the capacitive screen may be about to strike, if you want to use other objects (such as stylus, toothpicks, cotton swabs, etc.) to operate the capacitive screen, he will not give you any reaction.

A resistive touch screen is a sensor that converts the physical position of a touch point (x,y) in a rectangular area into a voltage that represents the x and y coordinates. Many LCD modules use resistive touch screens that can be used with four, five, seven, or eight wires to generate the screen bias voltage and read back the voltage of the touch point. The resistive touch screen is basically a thin film and glass structure, and the adjacent side of the film and glass is coated with ITO (nano-indium tin metal oxide) coating, and ITO has good conductivity and transparency.

When the touch operation, the ITO of the lower layer of the film will contact the ITO of the upper layer of the glass, and the corresponding electrical signal will be transmitted through the sensor, which will be sent to the processor through the conversion circuit, and converted into the X and Y values on the screen through calculation, and the selected action will be completed and presented on the screen.

Advantages of resistive screens:

1. The cost is cheap, and the response sensitivity is also very good.

2. It can adapt to all kinds of harsh environments, in any situation (such as going to the toilet, bathing, sauna), in any environment (such as rain, snow, high temperature, ultra-low temperature), with anything (such as nails, toothpicks, lighters, tongues) can accurately touch the resistive screen.

Disadvantages of resistive screens:

1. Only single touch, which means that you can only touch one place at a time, and if you touch another place, it will have no effect.

2. Due to the need for a certain amount of pressure, the resistance screen is easy to cause surface wear and tear for a long time, which affects the service life of the product;

3. The ability of resistance screen reactance is weak, and the ability to prevent malfunction is poor. Anything that touches it causes action.

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. Or you can't operate it with gloves in winter.

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.

Hope it can help the landlord.

Advantages of capacitive screens:

1. When using it, the force is lighter, as long as the fingers touch it.

2. The screen responds faster and more sensitive.

3. Support multi-touch.

4. Better visual effect in sunlight.

Disadvantages: Conductors must be used to touch the screen, such as fingers, but fingernails are not.

Resistance screen], pressure sensitive, requires force to react.

The advantage is that it can be precisely positioned, which is suitable for business applications such as documents. And ** is about 20% lower than the capacitive screen.

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 must be used with fingers to react, the resistance screen does not matter, the main thing is the pressure effect, the capacitive screen is the charge effect, so you can't use it with gloves in winter, which is the biggest difference in use.

I also think that the resistance is good and stable, and the response of the capacitor is slow! It's to treat our fingers as part of an electronic component!

At present, capacitive screens are more popular, and the sensitivity is usually relatively high, and the finger touch will respond. However, because it is a capacitive principle, the positioning accuracy is slightly poor, and a certain area of conductor contact is required to trigger, such as the bottom arc of a finger or a metal spoon. The capacitive screen supports multi-touch and can recognize multiple places you press on the screen at the same time.

Capacitive screens can usually be made of hard glass, which feels better. The capacitive screen has slightly poor anti-interference resistance, and the operation will be chaotic when the fingers sweat a lot or the screen is wet.

Resistive screens usually require a certain amount of force to trigger, and light touches can sometimes be unresponsive. It does not need to be conductive, and can be used with fingernail shells or small stick-like objects with slightly higher accuracy. The resistive screen is usually a soft material with more than two layers, and the screen will have a slight deformation during operation, and the feel is slight.

Difference. Capacitive screens are more expensive, and resistive screens are cheaper.

[Resistive screen] relies on the pressure of the finger on the screen to respond to the screen.

Advantages: not afraid of dust and water vapor, can be touched with any object, and has good stable performance.

Disadvantages: The sensitivity is not easy to adjust and uneven, and anything touching it will cause malfunction.

Capacitive screen] relies on the coupling capacitance formed by the human body's electric field between the finger and the screen conductor layer to work, and the human body must directly contact the screen to respond.

Advantages: high sensitivity, fast response, high light transmittance and clarity.

Disadvantages: Easily affected by temperature and humidity.

Multi-touch], in layman's terms, the screen supports several fingers to operate the screen at the same time, such as magnification**, many games that require multi-touch, etc., multi-touch basically refers to the capacitive screen, because the resistive screen relies on pressure to complete the touch, multi-touch may cause different strengths, and the screen will produce serious drift, so the general multi-touch refers to the basic capacitive cabinet screen.
