Capacitive Touch Screen Or Resistive Touch Screen Which Is More Advantageous?

capacitive touch screen Or Resistive Touch Screen Which Is More Advantageous?

Touch screen mobile phone capacitive touch screen and resistive touch screen are mainly different in these aspects. Such as touch sensitivity, accuracy, cost, multi-touch feasibility, damage resistance, cleanliness, visibility in the sun.

Touch Sensitivity Of Capacitive Touch And Resistive Touch

1)Resistive touch screen:there require pressto make contact with each layer of the screen. You can use your fingers (even if you wear gloves), nails, stylus, etc. to operate. Supporting stylus is very important in the Asian market, where there is very value with gesture and text recognition.

2)Capacitive touch screen: The smallest contact from the surface of a charged finger can also activate the capacitive sensing system under the screen. Non-living objects, nails, and gloves are invalid. Handwriting recognition is more difficult.

Precision

1)Resistive touch screen: The accuracy is at least a single display pixel, which can be seen when using a stylus. It is convenient for handwriting recognition and helps to operate under the interface with small control elements.

2)Capacitive touch screen: The theoretical accuracy can reach several pixels. But in fact, it will be limited by the finger contact area. This makes it difficult for users to accurately click on targets smaller than 1cm2.

Cost Of capacitive touch screen And Resistive Touch Screen

1)Resistive touch screen: very cheap.

2)Capacitive touch screens: Capacitive screens from different manufacturers are 10% to 50% more expensive than resistive screens.

Multi-touch Feasibility

1.Resistive touch screen: impossible, unless the circuit connection of the resistance screen and the machine is reorganized.

2.Capacitive touch screen: Many capacitive touch screens can reach 10 touch points.

Damage Resistance

1)Resistive touch screen:

The fundamental characteristics of the resistive screen determine that its top is soft. Need to be able to press down. This makes the screen very prone to scratches. Resistive screens require a protective film and relatively more frequent calibration. An advantageous aspect is that the resistive touch screen device using the plastic layer is generally not vulnerable to damage. It's not easy to break.

2)Capacitive touch screen: The outer layer can use glass. Although this is not indestructible. And it may shatter under severe impact. But glass is better for daily rubbing and staining.

Clean

1)Resistive touch screen: because you can use a stylus or nail to operate. It is less likely to leave fingerprints, oil stains and bacteria on the screen.

2)Capacitive touch screen: Use the entire finger to touch. But the outer glass layer is easier to clean.

Environmental Adaptability

1)Resistive touch screen: The specific value is unknown. However, there is evidence that the Nokia 5800 with a resistive screen can work normally at a temperature of -15°C to +45°C, and there is no requirement for humidity.

2)Capacitive touch screen: The typical operating temperature is between 0degree and 35 degree. And a humidity of at least 5% is required (limited by the working principle).

Visible In The Sun

1)Resistive touch screen: usually bad, the extra screen layer reflects a lot of sunlight.

2)Capacitive touch screen:

It uses the current induction of the human body to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of ITO (coated conductive glass). The outermost layer is a thin layer of silica glass protective layer, and the ITO coating is used as the working surface. , Four electrodes are drawn on the four corners, and the inner ITO is a shielding layer to ensure a good working environment.

When the finger touches the metal layer. The electric field of the human body, the user and the surface of the touch screen form a coupling capacitor. For high-frequency currents, capacitors are direct conductors. Then the finger draws a small current from the contact point. This current flows from the electrodes on the four corners of the touch screen. And the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller passes the accurate meter of the ratio of these four currents. Get the location information of the touch point.

Now, more people use capacitive screens. Because of its precise point location, it is easier to support multi-touch and other advantages. But at the same time, it is also more delicate, so everyone needs to take good care of it and take good care of it.
