Claims (1)

브라운관의 배기 방법에 있어서, 브라운관 내의 진공상태하에서 관내의 오염 및 가스 제거를 위하여 배기중에 전자총 전극을 로의 분위기가 200~300℃에서 고주파 전류를 650~800℃정도 G3전극에 열을 가하여 고주파에 의한 전자총의 전극 가열공정과, 탄산염의 열전자 방출특성을 얻기 위해 관내의 진공도가 10-4~10-5Torr 상태하에서 로의 하강온도 200~300℃범위 내에서 음극을 가열하여 탄산염의 열 분해를 행하는 탄산염 분해 공정과, 로의 온도 100~150℃의 범위에서 진공상태를 지속적으로 유지시키기 위한 전봉공정을 수행함으로써 브라운관의 배기 공정을 완료하게 되는 것을 특징으로 하는 브라운관의 배기 방법.In the evacuation method of the CRT, in order to remove the contamination and gas in the CRT under vacuum in the CRT, the electron gun electrode is heated at a temperature of 200 to 300 ° C. at a temperature of 200 to 300 ° C. to heat the G 3 electrode to a high frequency current of about 650 to 800 ° C. Thermal decomposition of carbonates by heating the cathode in the range of 200-300 ° C in the falling temperature of the furnace under the vacuum of 10 -4 to 10 -5 Torr in order to obtain the electrode heating process of the electron gun and the thermal electron emission characteristics of the carbonate. A method of evacuating a CRT, characterized in that to complete the CRT discharging step by performing a carbonate decomposition step and an electric sealing step to continuously maintain a vacuum state in a temperature range of 100 to 150 ° C. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
