Method for inspecting defect of the pixels in display panel device by image

PURPOSE: A pixel defect inspection method of display panel using the image process is provided to minimize the loss during manufacturing process by rapidly determining whether the individual pixel of the display panel is defective or not using the image process of line scan camera. CONSTITUTION: The image information of an OLED display is obtained(S110). The brightness value of each scan pixels out of the image information is analyzed(S120). The pixel region is separated from the background region(S130). The location of the OLED(Organic Light Emitting Diode) pixel is determined(S140).
