METHOD OF MANUFACTURING A CATHODE RAY TUBE |
摘要 |
The invention relates to a method of manufacturing a cathode ray tube (1). In the method, a cone part (4) of the tube is first provided with a first coating (13) so as to reduce an annoying crackling sound, whereafter a neck part (5) is connected to the cone part (4). Due to the presence of a closing element (20) on the cone part (4), said first coating is prevented from covering an inner surface of the cone part (4). As a consequence, the performance of the tube is not affected. A good quality of the connection is obtained if the layer thickness of the first coating (13) is equal to or less than 1 µm. A suitable material for the first coating is Antimony Tin Oxide combined with TEOS. |
