Patent JP-H02228693-A (JP)
Title: Display device
Inventor: KURITA HITOSHI
IPC: H01J31/15
Filed: 1989-03-01
Abstract: PURPOSE:To extend the luminance life of a fluorescent display tube by using fluorescent materials including a zinc sulfide phosphor for the fluorescent display tube and applying the filament voltage, which is >1.5 times as high as the rated voltage, for a prescribed time at prescribed time intervals. CONSTITUTION:AC 100V is supplied from an AC primary power source 1 to a low voltage transformer 2, and a power source 2C for the filament of a fluorescent display tube 3' using a zinc sulfide phosphor and a power source used for driving of a control means including a microcomputer or the like are provided on the secondary side of the low voltage transformer 2. Though S<4+> ions in the zinc sulfide phosphor are stuck to the filament, the voltage which is >1.5 times as high as the rated voltage is applied to the filament at prescribed time intervals for a prescribed time, for example, for several to 20 seconds at each time of power-on. Thus, the luminance life is considerably extended and improved the unevenness of luminance because the filament voltage is raised for a certain time and is activated.
