Touch screens have interior electromagnetic induction layer grid Guidelines

摘要

At least, and includes a case and a display screen, providing an inductive layer behind the display screen, connected to the inductive collection control circuit the output of the induction layer, electromagnetic grid guidelines is provided a control circuit of the display screen in a case A touch screen that was furnished induction layer, inducing layer is graticule nets that lattice arrangement formed by winding guidelines along the X, Y axis direction, the guidelines are insulated from each other at crossover points, each space of grid enclosing constitute the induction cell. The present invention, an electromagnetic induction layer is disposed on the rear surface of the display screen, because it uses as an identifier inducing device prints electromagnetic induction array antenna with a flexible membrane, production manufacturing easier, lower cost, cost benefits protrudes most, identification accuracy is high, by the touch of a finger or a pen, it is possible to type the exact handwriting information or mouse information to the cost of the prior art as the area is large. As the touch panel, and have a protective film on the surface of the display screen, physical wear is unlikely to occur, the service life is prolonged.
