Method for forming fluorescent screen of color cathode ray tubes using filter layer |
摘要 |
A filter layer for intercepting the undesired light passage is interleaved between the panel of a color cathode ray tube and the photosensitive phosphor coating, the photosensitive phosphor coating is backwardly exposed through the filter layer to actinic radiation of the back exposure to form phosphor elements with good adhesion and position.
