Accelerated Testing of Various Types of Vacuum Fluorescent Displays 890810

The VFD tests in this report differ from previous tests in that the anode and grid supply voltages, in addition to the filament supply voltage, were simultaneously increased from nominal values. Accelerated tests were conducted at 110%, 125%, and 150% of nominal voltage on VFD's having static and duplex drive with AC-driven filament and static drive with DC-driven Filament. Two methods are used to estimate the time at which 50% degradation occurs in luminance at nominal (100%) voltage. These methods were the inverse power law and regression analysis.
