Multipoint capacitive plate media
- Sep 14, 2018 -


Although the capacitance value is inversely proportional to the distance between the poles, it is directly proportional to the relative area and is also related to the insulation coefficient of the medium.Therefore, when a large palm or carrying conductor came near the capacitance screen not touch can cause the misoperation of capacitance screen, in the humid weather, this situation is particularly serious, walking live display, palms to display within 7 cm or body to display within 15 cm can cause misoperation of capacitive screen.Another drawback of capacitive screens is that they do not respond when touched by a gloved hand or an unconductive object in hand, due to the addition of a more insulated medium.
