Abstract

PURPOSE: To facilitate cut-off adjustment and improve performance of a colored cathode ray tube with an in-line three-beam type electron gun, by keeping its second grids independent, mechanically and electrically, of the cathodes.
CONSTITUTION: A color CRT1 used for character display is equipped with three in-line type cathodes 31, 32, 33 and solid No.1, No.3 and No.4 grids 4, 6, 7. It second grids 51, 52, 53 are independent of the cathodes 31, 32, 33 mechanically and electrically and applied with voltages E21, E22, E23, respectively. The brightness and size of characters displayed on the CRT1 are easily adjusted and improved in quality, by setting the voltage of No.1 grid 4 negative and changing the voltages of the second grids 51, 52, 53 to cut-off voltages one after another.
