Abstract

PURPOSE:To prevent a cathode-ray tube form being contaminated by an electron emission material and obtain stabilizedly treating stable and good emission characteristics by stabilizedly treating the electron emission material, vacuum-heating- degassing- it, and current-aging it. CONSTITUTION:The aging process of a cathode-ray tube is classified into three stages: (I) stabilized treatment of an electron emission material, (II) vacuum degassing, and (III) current aging. For example, in stage (II), a cathode is heated by setting the heater voltage to about 1.5 times rated voltage. This can prevent a cathode-ray tube from being contaminated by the electron emission material which was generated during current aging and obtain stable and good emission characteristics.
