I recently heard a woman on the subway They complained to her friend: the child of her family who has just learned to walk, want in all things "thrown" out - the coffee table, books, dishes and even her mother, just like the picture on the touch screen, a slide all disappear. Heard that this could not help but I think most of us users display screen behind the knowledge aboutwholesale cell phone skins?Before I started to really study the touch screen works, I think in the "swipable" phenomenon (referring to slide the screen) behind the existence of a common technology. But the fact is the opposite, I know nearly six kinds, cheap cell phone cases but most of them still under constant study. The two most commonly used system is the resistive and capacitive touch screen. For simplicity, I will focus here described these two systems to facilitate everyone's understanding.
A thin yellow layer, a resistance to another piece of electrical conductivity, the middle to be separated by an interval, until you go. (External layer is very thin, scratch-resistant blue film layer completely encased.) Current at all times throughout the those in the yellow layer, but when the finger touches the screen, two tablet being squeezed, the current point of contact changes. The software will recognize the current changes in these coordinates, buy cheap cellphone accessoriesperform the corresponding functions.
Although resistive touch screens durable, but because of the number of layers causes poor transmittance, not suitable for the user to read the experience. And they only single-touch, such as on the iPhone, with two fingers to zoom the picture will not be able to reach. This is why high-end electronic devices more inclined to use one of the reasons of the capacitive touch screen.
