ELECTRONIC DEVICE Russian patent published in 2023 - IPC H01Q1/52 H05K9/00 

FIELD: user electronic devices with information display capability.

SUBSTANCE: electronic device containing a display module configured to display an image, a motherboard containing a radio frequency circuit and a metal frame surrounding the display module associated with the radio frequency circuit and configured to receive or transmit radio frequency signals, includes a shielding structure located on the side of the display module closer to the system board and connected to the display module, in which the shielding structure comprises a metal shield, the metal shield is isolated from the metal frame and the RF circuit, and the metal shield is annular, the electronic device in which contains a near field communication circuit; and the near field communication circuit with the shielding structure are both located on the side of the display module closest to the system board. In this case, the shielding structure is located between the near field communication circuit and the display module; and the near field communication circuit is configured to transmit or receive the near field communication signal on the display module side through the open portion in the metal screen. The metal shield is isolated from the metal frame and the RF circuit, and can create a reflection between the metal frame and the display module, attenuating the field strength generated in the display module by the energy emitted by the metal frame, and shield the energy emitted by the metal frame to the display module to reduce absorption of energy radiated by the antenna by the absorbing material inside the display module.

EFFECT: increase of efficiency of antenna and simplification of the process of assembling the terminal.
