P-cap touch is Project capacitive touch, also called capacitive touch (CTP); with II2 interface, USB interface, support multi-touch, five points and ten points touch, with sensitive touch, users will have good and happy feeling when touch the screen or products.
Cover glass (cover lens) always do surface coating to reach special effect, like AG (anti-glare), AR (anti-reflection), AF (Anti-fingerprint) coating or treatment, we also have special touch controller solution that can support 7-8mm coverglass workable, water-proof workable, support gloves workable
When touch a capacitive touch panel, a small amount of charge is drawn to the point of contact, which becomes a functional capacitor. The change in the electrostatic field is measured to find the location. In some designs, circuits located at each corner of the panel measure the charge and send the information to the controller for processing. In multi-touch screens, sensors are arranged in a grid to enable more complex input.
Touch controllers brands are Cypress, ILI tek, Focal Tech, Goodix, ATMEL, ST, Hycon etc.
Input to resistive touch screens works through pressure resulting in two conductive layers being pressed together. In comparison, capacitive touch screens are not affected by outside elements, have high clarity and allow for easier functioning with lighter contact and greater accuracy.
Many current smartphones, tablets and other mobile devices are taken capacitive touch solution, including Android phones and Microsoft Surface, as well as Apple’s iPhone, iPad, iPod Touch, and Huawai smart phone.
