A new warehouse of cell phone jammer is under the construction

A new warehouse of cell phone jammer is under the construction.
In our first touch-screen can be traced back to be used in mobile devices, Motorola 1999 should be A6188. The emergence of this model we completely changed the concept of mobile phone operator, of course, more important is the introduction of mobile phone technology is the field of handwriting, while cell phone integration features are also shown signs of intelligent PDA Ni side. As was the technology matures, more and more of the touch screen is used on the phone, the identity of the goods from high above into the popularity of high-level people's basic technology, now almost a touch screen mobile phone market has accounted for nearly half the proportion of mobile phone . But the touch screen in the past for a long time to function as a hand-written mainly, we are often called touch-screen mobile phone to hand. But since the emergence of Apple's iPhone, it seems to break this tradition. Touch screen applications at once pulled up a whole new field, we know that the touch screen in addition to handwriting in addition to completely change the way we operate the equipment. The drawing of cell phone jammer is kept in the cabinet.
Let's take a look at the principle of touch screen technology. In the past we have access to a touch screen phone, for example, we mentioned earlier, Motorola A6188 or later PPC phone Dopod are using a technique called "resistive touch screen" technology. This screen is composed of two layers of conductive material coated with a transparent glass and plastic form, the user touches the screen, the two will fit within the conductive layer voltage makes the current location has changed and then get the touch point. And the other touch-screen technology, "projected capacitive touch screen" that is, the iPhone and Prada and other newer high end touch screen mobile phone technology used. Capacitive touch screen sensor using the body's current work. Capacitive touch screen is a four-layer laminated glass screen, glass screen and the inner surface of each coated with a layer of laminated ITO (conductive glass coating), the outermost layer is a thin protective layer of silica glass, ITO-coated as a working surface, leads to four electrodes on the four corners of the inner layer of ITO as a shield to ensure a good working environment. When the fingers touch the metal layer, because the body electric, users, and touch screen surface to form a coupling capacitor for high-frequency current, capacitance is directly conductor, so the finger contact point to take away from a very small current. Control wiring of cell phone jammer system should be carefully performed.
