Explanation
In laptops, the wireless network card (Wi-Fi/Bluetooth) is typically seated in the base unit, but its antenna leads are routed up through the hinges and along the edges of the LCD panel bezel. This placement maximizes signal range and quality by positioning the antennas as far as possible from the metal chassis, which can block or degrade wireless signals. These thin coaxial wires are clearly visible when disassembling a laptop display. They are not related to EMI shielding, additional backlights, or memory card readers.
