Abstract

PURPOSE: To solve the problem of the uneven coating density as well as to improve the quality of the luminous screen by securing an inversion between the rotary direction for the processes from the injection of the sensitive slurry containing the fluorescent substance through the high-speed shake-off of the slurry and the rotary direction of the drying process after the shake-off process.
CONSTITUTION: In the production of the color cathode-ray tube luminous screen, the processes 1W20 are applied to front panel grass 21. Starting at slurry injection process 3, processes 4 and 5 are carried out while panel glass 21 is turned slowly. After this, the high-speed rotations are given in the opposite direction to the hitherto rotations, and coating density adjustment 6 is given by shaking off the etxra amount of the slurry. Drying process 7 after the high-speed shake-off is performed in the opposite rotations to process 6 and with the revolution number of less than 1/3 the high-speed shake-off revolution number. In this way, the overcoating and undercoating are offset to solve the problem of uneven coating density at the area around glass 21, thus improving greatly the luminous uniformity of the luminous screen.
