An optical filter including: a base film (110); and a function incorporation layer (120) on the base film (110) for shielding electromagnetic interference and absorbing external light. The function incorporation layer (120) has a cross mesh pattern (122), wherein the cross mesh pattern (122) includes a plurality of pattern lines (122a, 122b), and wherein at least a part of the cross mesh pattern (122) protrudes from a surface of the function incorporation layer (120).

An electromagnetic wave shielding filter for a plasma display panel, for example, and a method of manufacturing such a filter includes preparing a substrate such as a metal plate that can act as a seed layer for electrolytic plating; forming a meshed plating layer on an upper surface of the metal plate; adhering an adhesive film to an upper surface of the plating layer; and separating the adhesive film from the metal plate so that the plating layer is adhered to a lower surface of the adhesive film. An electromagnetic wave shielding layer, which is installed to shield electromagnetic waves generated during the driving of a plasma display panel, for example, is formed in a mesh pattern, and the mesh pattern is created on a metal plate by electrolytic plating.

A cathode-ray tube apparatus capable of reducing a high frequency electric field radiated from the deflection yoke (3) and the deflection and high voltage circuit (4) to the outside of the cathode-ray tube apparatus (1). Mounted on the deflection yoke (3) or on the cathode-ray tube (2) are an induction coil (10) for generating a pulse voltage (e2) opposite in polarity to a high pulse voltage (e1) applied to the h (8) and an electric field cancellation electrode (6) made of a conductive wire to which the opposite polarity pulse voltage is applied. When the opposite polarity pulse voltage (e2, e3) is applied to the electric field cancellation electrode (6), the electric field cancellation electrode (6) radiates an electric field opposite in polarity to the high frequency electric field radiated from the deflection yoke (3) to the outside of the cathode-ray tube apparatus (1) to reduce the intensity of the high frequency electric field.

A television camera for colour television comprises several pick-up tubes (T1, T2, T3) which are arranged substantially horizontally or vertically in the camera. The pick-up tubes (T) each have a mu-metal shield (mul) against magnetism. Each substantially vertically arranged pick-up tube (T2, T3) has an additional second mu-metal shield (mu2, mu2'), which is absent for the horizontally arranged tube. The second shield may be in the form of a single plate (mu2) overlapping the pick-up tube or two plates (mu2, mu2') arranged on both sides of the pick-up tube and overlapping the tube. Deflection errors, especially in the corners of the television pictures caused by magnetic fields, are reduced to acceptable values.

A combined magnetic shielding and degaussing structure for an in-line color picture tube (21) comprises magnetizable shielding plates (34-37) of an extended surface area each located at a corner of the picture tube and two vertically oriented magnetizable strips (40.41). Each strip connects upper and lower corner shielding plates together on a respective side of the picture tube. The shielding plates guide stray magnetic flux into the strips and away from the picture tube interior in order to provide magnetic shielding. A degaussing winding (44;45) is wound around the vertical axis of each strip and generates a degaussing flux which flows through the shielding plates and into the color picture tube shadow mask.
摘要:
In a display device (70, 70A, 80-80G, 90-90F) having a display window (73, 81, 93), a magnetic loss layer or layer (75, 75A, 88-88C, 97-97C) is formed on at least a part of a principal surface of the display window. The magnetic loss layer may be a granular magnetic thin layer which is, for example, made of a magnetic substance of a magnetic composition comprising M, X and Y, where M is a metallic magnetic material consisting of Fe, Co, and/or Ni, X being element or elements other than M and Y, and Y being F, N, and/or O. The magnetic loss layer may be formed in any one selected from mat, lattice, stripe, and speck fashions. The magnetic loss layer may be formed in a mesh fashion.
摘要:
An electromagnetic-wave shielding material, such as a conductive mesh member 3, is bonded to a front surface of a PDP body 20 by transparent adhesives 4B, 4C and a transparent base plate 2 is bonded to a surface of the electromagnetic-wave shielding material by transparent adhesives 4A so that they are integrated together. In this way, electromagnetic-wave shielding efficiency is imparted to a display panel itself, thereby lightening its weight, making its wall thinner, reducing the number of parts, and thus improving the productivity and reducing the cost.

Tube à rayons cathodiques de couleur (10) portant une bobine (20a) faisant partie d'un collier de déviation (20) et enfermé dans un blindage de mumétal (30). Afin de réduire les effets du blindage (30) sur la déviation exercée par la bobine (20a), un blindage localisé (60a, 60b) recouvre au moins les extrémités (20c) de la bobine (20a) et dérive ou limite les champs magnétiques qu'elle crée, de manière que le blindage enveloppant (30) ne perturbe pas lesdits champs magnétiques.
