Abstract (en)
[origin: WO9104568A1] A color cathode-ray tube having at least a front panel, a funnel and an electron gun. A luminescent film is provided on the front panel. The luminescent film is produced in this manner. Red-light-emitting, green-light-emitting, and blue-light-emitting phosphor layers are repetitively laminated with nonluminescent layers interleaved. The laminate is cut along its thickness into films and baked. This makes it possible to efficiently produce a cathode-ray tube having a color luminescent screen that features very high accuracy and high resolution, and that can be adapted to small CRTs.
