Abstract

This invention presents an automatic optical test machine for determining the defect of color non-uniformity of a panel, which includes a gantry structure; a moving carrier of panels placed at the bottom of the gantry structure to support the panel to be tested; the moving carrier of panel can move to transfer the panel synchronously in x-axis and y-axis, also can move at an inclined angle; at least a first light source, exit of which is set to be long and narrow; at least a first image capturing device placed on the gantry structure, wherein the first image capturing device is a line-scanned camera with a first specific viewing angle; and at least a first light sensor located near the exit of the first light source; light signal of the first light sensor and the picture-taking sequence of the first image capturing device can be synchronized; using the moving carrier of panels to move the panel at an inclined angle, after the image is captured by the first image capturing device at the first specific viewing angle and processed by a computer software, one can determine whether the test panel contains defects of color non-uniformity or not.
