The difference between capacitive touch screen and resistive touch screen

The difference:

1. Touch sensitivity

The capacitive screen uses the current induction of the human body to work, so any non-conductive objects such as fingernails, gloves, etc. can not be identified by the capacitive induction system below the screen; The resistive screen works through pressure sensing and can be touched with any object, supporting a stylus.

2. Feasibility of multi-touch control

The multi-touch control of capacitive screen can be realized, depending on the way of implementation and the software used. The multi-touch of the resistance screen cannot be achieved unless the resistance screen is reassembled and connected to the circuit of the machine.

3. Damage resistance

The outermost layer of the capacitive screen is the silica glass protective layer, which is likely to break under severe impact; The outermost layer of the resistance screen is a film, which needs to be pressed down to achieve pressure sensing, and the resistance screen supports stylus, making the screen easy to scratch, the need for protective film and relatively more frequent calibration, but more difficult to break than the capacitor screen.

4. Accuracy

In theory, the capacitive screen can reach several pixels, but in fact, due to the limitation of finger contact area, it is difficult for users to accurately click the target less than 1cm; The precision of the resistive screen is at least a single display pixel, which can be seen when using a stylus. Handwriting recognition is easy and helps to operate in an interface that uses small control elements.

5. Visual effect

Capacitive screen and resistance screen in the indoor visual effect is very good, but in the outdoor, especially in the sunlight, the visual effect shows a difference. Capacitive screens work better, but resistive screens are less visible because the extra screen layer reflects sunlight.

6. Degree of cleanliness

Capacitive screen to use fingers to touch, easy to leave stains on the screen, but because its outermost layer of glass layer, easier to clean; The resi6. Degree of cleanliness

Capacitive screen to use fingers to touch, easy to leave stains on the screen, but because its outermost layer of glass layer, easier to clean; The resistance screen supports the operation of stylus or fingernail, which is not easy to dirty the screen.

7. Environmental adaptability

Capacitive screens typically operate at temperatures between 0° and 35° and require at least 5% humidity. There is no specific value for the operating temperature of the resistive screen, but it has been confirmed that the resistive screen used by the Nokia 5800 can work normally at a temperature of -15°C to +45°C, and the resistive screen has no requirements for humidity.

8. Cost

Capacitive screens are more expensive, and capacitive screens from different manufacturers are about 10% to 50% more expensive than resistance screens; The resistance screen is relatively cheap, and some cottage machines on the market are mainly based on resistance screens.

9. Power consumption

Capacitive screens consume more electricity than resistive screens.
