Abstract

The conventional thermionic cathode was replaced with a cold cathode and the Mo-tip FEA was applied to the electron gun of the CRT. To replace the cathode part of the electron gun of the CRT, the Mo-tip FEA was newly designed according to the specification of the electron gun of the CRT. The fabricated Mo-tip FEA was mounted on the base plate and then the cathode part and focusing electrode part was assembled using the electrical-welding method. The fabricated electron gun with the Mo-tip FEA cathode showed better performance in terms of emission current and switch-on time, even though the gate current was decreased due to the nonuniformity of the electric field by grid G2 and the strong repulsive force of G1 having grounded potential. Finally, the potential applicability was guaranteed by means of operating the 19 in. color CRT using the fabricated electron gun with the Mo-tip FEA.
