<p>A touch control display screen apparatus with a built-in electromagnet induction layer of conductor grids, at least comprising a display screen and a housing, an induction layer is in the rear of the display screen, and the outputs of the induction layer are fed to an induction acquisition control circuit, a display screen control circuit is within the housing, the induction layer is a graticule lattice circled by the conductors along the directions of X, Y axis, with twisted roots and gnarled branches, and the conductors are insulated at the cross point each other, the space enclosed by each grid forms an induction cell. Because the electromagnet induction layer is setted in the rear of the display screen and adopting soft septum to print the electromagnet induction as identifying induction apparatus, the invention has the advantages of easy manufacture, lower cost, and the area is more big, the cost advantage relative to the prior arts is more obvious; the invention has high precision of identification, and may enter the informations of the mouse or handwriting by stylus touch or finger correctly; as a touch screen, due to the protective film covered on the surface of the display screen, it is not easy to bring physical damages, therefore the work life is long.</p> |
