Abstract

PURPOSE:To avoid such inconvenience where a CRT filter is injured in a molding process at an area adhering a CRT by using a removable protection film to protect the CRT filter. CONSTITUTION:The high nitrile resin is especially suited to a CRT filter in terms of adhesive properties and molding properties. It is preferable to form the CRT filter into a lamination sheet containing a net that produces no interference fringe with a CRT scan line or has open joints to produce substantially no after-image even through the interference fringes are produced together with its surface covered with a metal and a synthetic resin sheet or film. Then a removable protection film is tentatively attached on both sides of said lamination sheet. In such a way, a satisfactory CRT filter is obtained.

CRT display devices such as ammeters and analytical instruments have become indispensable in offices, homes, and factories. Along with this, the number of operators who come into close contact with CRTs for long periods of time is increasing, and in developed countries, occupational diseases of operators are increasingly being treated as a social problem. A common symptom of this occupational disease is fatigue of the optic nerve, and although the scientific cause and effect relationship has not been fully elucidated, the risk of adverse effects from exposure to electromagnetic waves, static electricity, ultraviolet rays, etc. must be taken into account.

(Problems to be Solved by the Invention) Since commonly used CRTs have a curved surface, when a flat CRT filter is attached, the display often appears blurred, especially in a part of the corner of the screen. The reality is that operators are inconvenienced by having to remove the CRT filter when working.

Furthermore, conventionally proposed CRT filters require a special frame to be attached so that they can be removed.
CRT filters are also becoming increasingly expensive. Furthermore, when handling a CRT filter that is structured to be in close contact with the CR7 surface, extreme care must be taken not to damage the filter surface during the manufacturing process.
