Title:
GLARE PREVENTION FILM FOR SCREEN OF CATHODE-RAY TUBE AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JPH1140082
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To remove the necessity of manufacturing glare prevention film for every size of a cathode-ray tubes, and also to reduce the number of parts, further, make it roll possible to wind in a to store and carry, by using a film which has planar contact on at least one side, and a reflectance of a specific % range in reflection of a specific angle. SOLUTION: A glare prevention film for a screen of a cathode-ray tube has both planar contact and a glave prevention characteristic. With respect to the contact, the exfoliating force (shear exfoliation strength) is preferably 0.1-50 kg in the case of a prescribed test procedure. And, this film has a reflectance of the range 10-50% in reflection at 60 deg.. The film with these efficiencies can be closely contacted with, and attached on, the screen of the cathode-ray tube, only by being oppositely contacted with the screen of the cathode-ray tube and being pressured slightly. Also, it can be prepared for the screen of the cathode-ray tube only by being cut out according to the size of the screen of the cathode ray tube, therefore there is no need to manufacture various sized films.
