Patent ID: 11825587

Abstract:
A viewing panel (30, 40, 50, 60, 70, 80) for a domestic appliance includes a substrate (33, 43, 53, 63, 73, 83) and a conductive layer (35, 45, 55, 65, 75, 85) disposed on the substrate; the conductive layer having conductive lines (31, 41, 51, 61, 71, 81) forming a pattern. The substrate contains a polymeric material; the conductive lines have a height (H) of 0.5 micrometers to 10 micrometers determined by an Olympus MX61 microscope; and the pattern has an average pore area of 0.008 square millimeters to 0.06 square millimeters determined by an Olympus MX61 microscope. The viewing panel has: a total transmission of greater than 70% of light having a wavelength in the range of 360 nanometers to 750 nanometers; and an electromagnetic shielding efficiency of greater than 30 dB at 2.45 GHz.
