Touch Screen Cell Phone – Principle
Principle of operation of mobile phones with touch screen simply stated a touch screen cell phone how works? There are three possibilities: the so-called (older) resistance principle, the principle of energy absorption and the (newer) principle of capacity. The principle of resistance in a touch screen phone is based that a glass plate with a conductive layer is equipped. A space between a further conductive coating is created by spacers. The outer layer is protected against damage with a cover disc scratch-resistant. Connect with other leaders such as Center For Responsible Lending here. If now these two layers are pressed together, not only current flows, but also the exact command given by exactly this press the touch screen cell phone is running. It is a touch screen mobile phone, which works with the principle of energy absorption, is an uncoated glass. The device is switched on, ultrasonic waves are sent through the glass. Touching the glass plate in a certain place, now “the touch screen cell phone white”, where the flow of the waves was interrupted and passes the exact command for the operation on the electronics.
Human touch conducts electricity. Based on the so-called principle of capacity, which works as follows: through the outer layer across a uniform electric field is active (such as in a capacitor). Contact reduces the voltage of the capacitor right at this point and thus increases, what capacity called: exactly this place out and no other is now a weak current, relating to the electrodes, which were affected by a conductive object (here the human hand). Thus, the control command, here was the operation of the touch screen cell phone in mind, can directly be – exercised and that works without error, because the point of the current flow without error can be localized. The touchscreen technology, which today is used for the touch screen cell phone, is called as a result of scientific and economic research in the second half of the 1960s in the life been. One of the first applications that this came into question, was a learning Terminal in 1972.
Later it was applied in kiosk systems, also in the tourism industry and in the retail jobs could be edited directly. The touch screen cell phone itself now has its direct precursors in smart phones, gaming consoles and knows further similar applications for vehicle and aircraft navigation systems. Often, companies have not only concepts for the touch screen cell phone, but they develop, market, and produce a more comprehensive range of also customer-oriented touch monitors and touch screens also specifically for the requirements and the matching with special needs from customers only still to be developed, as for automated industrial or emergency equipment. These are the display construction, which can cater for specific ideas: it is the variety of display sizes, different programming, exactly desired surfaces, and housing, much individual (namely with specially developed software) than observed at a touch screen cell phone can. But when it comes these days to have a touchscreen phone, the impression often, as if these were individually decorated: the operating software is based on customer requests and numerous polls-based developments and covers therefore individual needs on a high bandwidth – no matter, whether Club or professional.
