SYSTEM OF MEASURING PROPERTY OF LOW VOLTAGE PHOSPHOR

摘要

PURPOSE: A system of measuring a property of a low voltage phosphor is provided to allow to analyze the property of a phosphor before a display device is manufactured, thereby improving the productivity of the display device. CONSTITUTION: In a system of measuring a property of a low voltage phosphor, a vacuum chamber(12) maintains a vacuum state. A sample tube is mounted in the vacuum chamber and includes a low voltage phosphor sample. A filament is mounted in the vacuum chamber to emit a thermal electron upon applying a voltage. A sensing device is mounted in the vacuum chamber to sense the sated-radiative of a low voltage phosphor sample placed on the sample tube. A mesh grid(36) is provided between the filament and the sample tube to accelerate the thermal electrons emitted from the filament toward the sample tube.
