Patent ID: 7796122

Claim:
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.
