    • PURPOSE: A method for automatically inspecting for smudges on a polarizing plate by using color difference analysis is provided to monitor a smudge extent of a polarizing plate in real time in a producing line, thereby enhancing quality management and reducing manufacturing time. CONSTITUTION: A method for automatically inspecting for smudges on a polarizing plate by using color difference analysis is as follows: An inspection polarizing plate or a polarization device is mounted on one or more reference polarizing plates(S100). Lights are irradiated on the inspection polarizing plate or polarization device(S200). The inspection polarizing plate or polarization device are photographed(S300). Color differences of each pixel are calculated by using data extracted from the photographed images. The extent of a smudge is digitized by using the calculated color difference data(S470).

    • PURPOSE: A method for automatically inspecting a smudge on a polarizing plate by using a color difference analysis is provided to enhance a quality managing ability, to reduce manufacturing time, and to improve producing efficiency. CONSTITUTION: A method for automatically inspecting a smudge on a polarizing plate by using a color difference analysis comprises an inspection unit(40), a light source unit(10), a photographing unit(50), and an computing unit(60). The inspection unit comprises one or more reference polarizing plates(20) and an inspection polarizing plate or polarization device(30). The inspection polarizing plate is mounted on one or more reference polarizing plates. The light source unit is arranged on a surface of the inspection unit and irradiates lights on the inspection unit. The photographing unit is arranged on the other surface of the inspection unit and photographs the inspection polarizing plate or polarization device and transmits images thereof to the computation unit. The computation unit analyzes color differences of the transmitted images of the inspection polarizing plate or polarization device per each inspection region, thereby detecting the minute smudge and quantifying the same as a numeric data.
