Abstract: A display substrate tester and a method thereof are provided to enhance the accuracy of a visual inspection by automatically producing the height of a protrusion formed on a display substrate. A display substrate tester(100) comprises a light source part(120), an image pickup part(130) and a measuring part(140). The light source part(120) emits light and provides it to a display substrate(200) on which a color filter layer is formed and which reveals a specific color using the light provided from the light source part(120). The image pickup part(130), such as a camera, etc., installed at the upper part of the light source part(120), photographs a protrusion area, where a protrusion is formed on the display substrate(200), and a peripheral area, which encloses the protrusion area, and creates a test image. The measuring part(140) receives the test image from the image pickup part(130), produces the color coordinate value of the protrusion area and the color coordinate value of the peripheral area on the basis of the test image, and obtains the height of the protrusion.

Abstract: An apparatus for inspecting a flat panel display and a method thereof are provided to determine a failure of a color filter accurately within a short time by measuring changes in color coordinates and the width of a color filter at several positions. A method for inspecting a flat panel display includes the steps of: discriminating whether a stain exists on a color filter or not(S110); photographing the stain on the color filter and plural positions around the stain(S120); measuring the amount of change in color coordinates at the plural positions(S130); and determining the color filter is a failure if the change amount is larger than a reference value(S140).

Abstract: An apparatus and a method for inspecting an alignment film of a liquid crystal display are provided to improve detection performance of alignment film defects by increasing dispersion of light. An apparatus for inspecting an alignment film of a liquid crystal display includes an illumination apparatus(10), a charge coupled device(20), an image processor(40), and a transfer device(30). The illumination apparatus is spaced apart from a substrate(100) on which an alignment film(11) is formed. The charge coupled device is spaced apart from the illumination apparatus. The image processor is connected to the charge coupled device. The transfer device mounts the substrate thereon to convey the substrate. The image processor checks defects of the alignment film using an image generated by the charge coupled device.
