Apparatus for inspecting a fluorescent substance on a plasma display

摘要

An apparatus for inspecting the coating of a fluorescent substance on a plasma display panel includes an illumination device for irradiating UV light onto the fluorescent substance for causing the fluorescent substance to emit light, and an imaging device for picking up the emission of the fluorescent substance. A filter, that lets only light of certain wavelengths in accordance with light emission characteristics of the fluorescent substance pass, is arranged between the imaging device and the panel being inspected.
