Resistive touch screen, commonly known as "soft screen", is mostly used in mobile phones with Windows Mobile system.
Capacitive touch screen is commonly known as "hard screen", such as iPhone, G 1.
Comparison between Resistance Screen and Capacitance Screen
First, indoor visual effects are usually good.
Second, touch sensitivity.
1, resistive touch screen: it needs pressure to make all layers of the screen contact, and you can use your fingers (even if you wear gloves), nails, stylus, etc. Supporting the stylus is very important in the Asian market, and gestures and character recognition are highly valued everywhere.
2. Capacitive touch screen: The slightest contact on the surface of a charged finger can also activate the capacitive sensing system at the bottom of the screen. Inanimate objects, nails and gloves are invalid. Handwriting recognition is difficult.
Third, accuracy.
1, resistive touch screen: the accuracy reaches at least a single display pixel, which can be seen with a stylus. Handwriting recognition is convenient and it is helpful to operate in an interface with small control elements.
2. Capacitive touch screen: In theory, the accuracy can reach several pixels, but in practice it will be limited by the contact area of fingers. It is difficult for users to accurately click on the target smaller than 1cm2.
Fourth, cost.
1, resistive touch screen: very cheap.
2. Capacitive touch screen: Capacitive screens from different manufacturers are more expensive than resistive screens 10% to 50%.
Verb (abbreviation of verb) feasibility of multi-touch
1, resistive touch screen: impossible unless the resistive screen is connected to the circuit of the machine.
2. Capacitive touch screen: According to different implementation methods and software, most mainstream mobile phones already support capacitive touch screens (except Nokia).
Sixth, the ability to resist losses
1, resistive touch screen: The fundamental characteristics of resistive screen determine that its top is soft and needs to be pressed. This makes the screen very prone to scratches. Resistive screens require protective films and relatively more frequent calibration. On the positive side, resistive touch screen devices using plastic layers are usually less prone to damage.
2. Capacitive touch screen: the outer layer can be made of glass. Although this is not indestructible, and it may break under severe impact, glass is still good for daily friction and stains.
Seven. clean
1, resistive touch screen: Because it can be operated with a stylus or nails, it is more difficult to leave fingerprints, oil stains and bacteria on the screen.
2, capacitive touch screen: touch with the whole finger, but the glass outer layer is easier to clean.
Eight, environmental adaptability
1, resistive touch screen: the specific value is unknown. However, there is evidence that Nokia 5800 with resistance screen can work normally at-15 C to+45 C, and there is no requirement for humidity.
2. Capacitive touch screen: The typical working temperature is between 0 and 35℃, and at least 5% humidity is required (limited by working principle). Nine, the visual effect in the sun
Resistive touch screen: usually broken. The extra screen layer reflects a lot of sunlight.
