20090231299 | TOUCH CONTROL DISPLAY SCREEN APPARATUS WITH A BUILT-IN ELECTROMAGNETIC INDUCTION LAYER OF WIRE LATTICE - A touch control display screen with a built-in electromagnetic induction layer of wire lattice includes at least a display screen and a housing. An induction layer is provided behind the display screen and is connected to the induction collection control circuit by its output. A control circuit of display screen is provided in the housing. The induction layer is a wire lattice winded and interlaced separately by the wires along the X and Y axes. The wires are insulated with each other at the crossing points. The space within each lattice unit constitutes one induction cell. Because the electromagnetic induction layer is placed behind the display screen and a printed electromagnetic induction antenna array with flexible membrane is adopted as a recognition induction element, it is easy to manufacture and the cost is low. | 09-17-2009 |
