Touch control display screen with a built-in electromagnet induction layer of septum array grids
First Claim
1. A touch control display screen with built-in membrane antenna array lattice electromagnetic induction layer, including at least a display screen and a shell;
- wherein an induction layer is provided in the rear of the display screen, an output of the induction layer is connected to an induction control circuit, a display screen control circuit is also provided in the shell, wherein;
said induction layer is an antenna array formed by silver-plasm or mixture of silver-plasm and carbon-plasm which is printed on an insulation membrane and arranged along X, Y axes, therein the area enclosed by each lattice unit of the antenna array constitutes one induction cell;
said insulation membrane is made by film material;
there are two or more said induction layers, and the induction cells on respective induction layers are set to interlace each other;
a shield layer is provided after the induction layer; and
a buffering layer is further provided between the induction layer and the shield layer in order to keep a space between the induction layer and the shield layer.

Abstract
A touch control display screen with built-in membrane antenna array lattice electromagnetic induction layer, including at least a display screen and a shell; wherein an induction layer is provided in the rear of the display screen, the output of the induction layer is connected to an induction control circuit, a display screen control circuit is also provided in the shell; the induction layer is the antenna array printed on the insulation membrane and arranged along the X, Y axes, therein the area enclosed by each lattice unit constitutes one induction cell. Because the electromagnetic induction layer is provided in the rear of the display screen and flexible membrane-type, printed electromagnetic induction array antenna is used as the identifying induction component according to the present invention, the manufacture is easy, the cost is low, and the advantage in cost-cut is prominent in comparison with the prior art when the area of the display screen is larger. The accuracy of identification is high, and the mouse information or handwriting information can be input exactly by means of brush strokes of finger strokes; as a touch screen, the display screen is covered by a protecting film to avoid the physical damage, so it has long operating life.
