Systems and methods for improving transparency of display devices to wireless signals

Abstract:

A wireless communication device has a display device and a transmitter that wirelessly transmits a wireless (e.g., NFC) signal from an antenna. The antenna is positioned such that the display device may be between the antenna and another wireless communication device that is to receive the signal, and the display device may attenuate such signal. A reflector of the display device is patterned with small gaps in order to limit the loop sizes of eddy currents that are induced by the wireless signal, thereby reducing parasitic power consumption of the reflector to the wireless signal. Thus, the presence of the gaps in the reflector improves the transparency of the display device to the wireless signal without significantly affecting the performance of the reflector in sinking heat and reflecting light.
