Patent ID: 8152584

Claim:
A method for manufacturing a cold cathode fluorescent lamp (CCFL), which comprises a light transmitting shell and an electrode disposed at one end of the light transmitting shell, the method comprising steps of: an exhausting step of exhausting a gas inside the light transmitting shell via a vent of the light transmitting shell; a charging step of charging at least one inert gas into the light transmitting shell; and an amalgam disposing step of initially disposing an amalgam inside a gas adjusting instrument, and removing the amalgam into a temporal region of the light transmitting shell after the exhausting step, wherein after the charging step, the method further comprises a sealing step of sealing the vent of the light transmitting shell, wherein after the sealing step, the method further comprises an impurity gas absorbing step of sputtering a material of the electrode onto an inner wall of the light transmitting shell by using a high-voltage AC power to drive the electrode, wherein a metal layer or a metal film is directly formed on the inner wall of the light transmitting shell adjacent to the electrodes during the impurity gas absorbing step.
