Do you know the advantages and disadvantages of capacitive touch screens?


1. The capacitive touch screen only needs to be touched lightly, without any pressure to generate a signal.

2. The capacitive touch screen only needs one time or no calibration at all after production, and the resistance technology needs normal calibration.

3. The capacitor solution has a long life. Because the parts of the capacitor touch screen do not need to move. In a resistive touch screen, the upper ITO film needs to be thin enough to be flexible so as to bend downward to contact the lower ITO film.

4. Capacitance technology is superior to resistance technology in terms of light loss and system power consumption.

5. The choice between capacitive technology or resistive technology mainly depends on the object that touches the screen. If you touch it with your fingers, the capacitor touch screen is a good choice. If you need to touch with a stylus, whether it is plastic or metal, resistive touch screens can do the job. The capacitor touch screen can also use a touch pen, but a special touch pen is required.

6. The surface capacitor type can be used for large touch screens, and the correlation is low, but it cannot support gesture recognition now: the induction capacitor type is mainly used for small and medium touch screens and supports gesture recognition.

7. Capacitor technology is wear-resistant, has a long service life, and has low maintenance costs when users use it. Therefore, the overall operating cost of the manufacturer can be further reduced.

8. Capacitive touch screen can support multi-touch technology, unlike resistive touch screen, it is slow to respond and not easy to wear.


1. Unstable. The method of coupling capacitor is directly affected by temperature, humidity, finger humidity, human body weight, and dryness of the ground. The interference of large-area external objects is also very large, resulting in unstable results.

2. The defective rate is higher than that of resistive screens. The very thin glass on the outermost surface usually has very good anti-friction properties, but the technology requires that it be manufactured under vacuum. This very thin glass has a 5% probability of hitting the product with holes.

3. The life span is shorter than that of resistive screens (3 years for resistive screens and 2 years for capacitive screens).
