Electromagnetic shielding device of image display equipment

摘要

The present invention relates to an electromagnetic wave shielding device of an image display device. In the related art, a shielding material and a metal band are locally applied to a rear surface of an image display device, but a cause of misconvergence of a monitor occurs due to magnetization of the metal band. It was. In addition, although the entire back of the monitor is shielded with aluminum, the price of aluminum is considerably higher than that of metal, which leads to an increase in production cost, thereby greatly reducing the price competitiveness of the assembly parts and requiring additional adjustment work inside the monitor. In this case, since the entire aluminum shield may be separated from the rear of the monitor, repair and adjustment workability of the monitor may be greatly deteriorated.;Accordingly, the present invention provides a non-magnetic member (eg, an aluminum plate) that can be opened and closed to a predetermined portion of the shield metal to prevent misconvergence caused by magnetization of the shield metal shielding electromagnetic waves generated from the image display device. , Eliminating the cause of the monitor's misconvergence caused by the magnetization of the shield metal, and reducing the production cost of shielding the entire back side of the monitor with aluminum, greatly improving the price competitiveness of the assembly parts. It is to make additional adjustment or repair work on the inside more convenient without removing the shield metal.
