Front Screen Glass Lens For Iphonex13promax with OCA

                                                                                Applications of touch screen
     According to the analysis of the structure, principle and performance characteristics of the touch screen, the applicable occasions of different touch screens are as follows.
     Four-wire resistive touch screen: it is not afraid of dust, oil and photoelectric interference, and its main defect is that it is afraid of scratches. Suitable for public places with fixed users, such as industrial control sites, offices, homes, etc.
     Five-wire resistive touch screen: excellent sensitivity and light transmittance, long service life, not afraid of dust, oil and photoelectric interference, suitable for all kinds of public places, especially for industrial control sites that require precision.

     Capacitive sensing touch screen: Because the capacitance changes with temperature, humidity or grounding conditions, its stability is poor and drifting phenomenon often occurs. Afraid of electromagnetic field interference and drift, it is not easy to use in industrial control places and places with interference. It can be used for public information inquiries that require less precision; frequent calibration and positioning are required.
     Infrared sensor touch screen: low resolution, but not subject to current, voltage and static interference, suitable for some harsh environmental conditions; suitable for various public places, offices and industrial controls that do not require very precise interference without infrared and strong light interference on site.
     Surface acoustic wave touch screen: pure glass material, best light transmission, long service life, good scratch resistance, suitable for various public places with unknown users. But it is afraid of long-term dust accumulation and oil pollution, so it is better to use it in a clean place. Otherwise, regular cleaning service is required.
