Display panel inspection apparatus and display panel inspection method

Abstract

It is an object of the present invention to provide a display panel inspection apparatus and an inspection method capable of remarkably reducing equipment cost and shortening inspection time. The apparatus comprises: an image measurement unit which lights a display panel (work) in response to a test signal and pick up an image of the lighted display panel, thereby obtaining image measurement data; a data accumulating unit for accumulating the image measurement data of a plurality of display panels as data corresponding to the respective display panels; and a data processing unit which respectively reads out the image measurement data accumulated in the data accumulating unit and performs image processing so as to judge the quality of each display panel. When inspecting a plurality of display panels, the image measurement unit and the data processing unit perform inspections independently. The image measurement unit operates to output identification data for identifying the respective display panels acting as measurement objects and image measurement data to the data accumulating unit, while the data accumulating unit forms a data base for managing the identification data and the image measurement data corresponding to the identification data.
