TOUCH SCREEN, SCHEME OF ITS CONTROL AND METHOD OF ITS CONTROL AND DEVICE OF A TOUCH SCREEN Russian patent published in 2018 - IPC H01Q1/22 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. Touch screen contains a display screen, first layer of transparent medium, transparent connective layer and transparent antenna layer, first layer of transparent medium being placed between the connective layer and antenna layer, and the connecting layer is placed between the first layer of the transparent medium and the display screen. In this case, the antenna layer includes multiple antenna units, and the multiple antenna units include the first antenna unit and multiple second antenna units. First antenna unit is configured to transmit a read signal, and the second antenna units are configured to receive the reflected read signal signals. Reflected signals are generated by the touch input object by reflection of the read signal, or the first antenna unit and the second antenna units are configured to simultaneously transmit or receive a communication signal, and multiple second antenna units are interleaved with the first antenna unit. Connective layer includes a shield layer and an earth layer, shield layer being adapted to shield the antenna layer and return the communication signal, read signal and reflected signals, and the earth layer is configured to ground the antenna layer.

EFFECT: proposed invention relates to wireless communication.
