ELECTRONIC DEVICE COMPRISING DISPLAY MODULE HAVING STRESS NEUTRALIZATION LAYER BETWEEN FLEXIBLE SUBSTRATE AND CONDUCTIVE LAYER

WIPO Patent Application WO/2019/103414

A1

The present invention provides an electronic device having an electromagnetic wave shielding structure for preventing antenna performance degradation. The provided electronic device comprises: an antenna disposed in a partial region of the electronic device; a printed circuit board; and a display module comprising a display panel, one or more signal wires connected to the display panel, and a flexible substrate on which the one or more signal wires are arranged. The flexible substrate comprises: a conductive layer connected to the printed circuit board in the curved state and configured to shield an electromagnetic wave emitted from the one or more signal wires to the antenna; and a stress neutralization layer, the material of which can be deformed with the passage of time in response to the shape of the flexible substrate connected in the curved state. The stress neutralization layer may be disposed between the flexible substrate and the conductive layer.
