Problems solved by technology

[0009] However, it is difficult to obtain resolution in the metal area that provides an appropriate aperture ratio by using a printing method that alone forms an electromagnetic shield.
Therefore, this method is not currently used

example

[0099] The total amount of all ingredients making up the composition is partially described in each example.

[0100] FODEL(R) silver paste manufactured by DuPont was used as a photosensitive thick-film conductive paste, FODEL(R) ruthenium oxide paste manufactured by DuPont was used as a photosensitive thick-film black paste, and soda-lime glass having a thickness of 2.5-3 mm was used as a glass substrate. For good visibility, the glass substrate must be of good quality, free from defects such as internal bubbles and surface scratches.

[0101] FODEL® ruthenium oxide paste (manufactured by DuPont) was used as a photosensitive thick film black paste, and the photosensitive thick film black paste was screen printed onto a 2x3 inch glass substrate (high yield point glass) by using a 380 mesh polyester screen. PD200, manufactured by Asahi Glass Co., Ltd.), and in a batch-type hot air drying furnace, dry with a peak temperature of 80 ° C and a total of 20 minutes of profile (profil...

Abstract

The present invention relates to a light-transmitting electromagnetic shield having an electromagnetic shield that reduces the emission of electromagnetic waves when mounted in front of a display such as a plasma display panel (PDP), cathode ray tube (CRT) or electroluminescent (EL) display performance, with high visible light visibility, low reflectivity to ambient light, and excellent durability.

Description

field of invention [0001] The present invention relates to a light-transmitting electromagnetic shield which, when installed in front of a display such as a plasma display panel (PDP), cathode ray tube (CRT) or electroluminescent (EL) display, has reduced Electromagnetic shielding performance for electromagnetic wave emission, high visible light visibility, low reflectivity to external light, and excellent durability. Background of the invention [0002] The rising performance of plasma displays and other large screen displays has led to a growing interest in techniques for shielding electromagnetic radiation emitted by display devices. In particular, as the use of display devices such as home televisions grows, the proportion of displays worldwide that are required to comply with the US Federal Communications Commission (FCC) Class B standard is steadily increasing. At the same time, attention shifted from concern about electromagnetic wave interference (EMI) between machi...
