Patent ID: 7859274

Claim:
A system for testing a flat panel display having a flat display panel assembly, comprising: a testing stage for arranging the flat display panel assembly; a measuring apparatus being disposed on the testing stage and for measuring a spectrum of a transmitted light passing through a measuring region of the flat display panel assembly from a light source; a transporting apparatus for moving the measuring apparatus at a constant acceleration on the testing stage; and a defect informing apparatus being electrically connected to the measuring apparatus and for informing of an existence of a defect, a type of defect, and a severity of defect by processing an electrical signal of the spectrum transmitted from the measuring apparatus, wherein the measuring apparatus comprises a case having a plurality of measuring heads at a front thereof, the case including a focusing unit for focusing the transmitted light passing through the measuring region of the flat display panel assembly; a spectral unit for separating the collimated light into each wavelength; and a photoelectrical conversion sensor for absorbing the light that is separated into wavelengths and respectively converting the optical signals therefrom into an electrical signals, wherein the focusing unit is connected to the spectral unit by an optical fiber.
