Abstract
The present invention discloses an apparatus for automatically inspecting image quality of LCD panel, which captures the test pattern screen of the LCD panel by at least two sets of optical image capturing modules. The captured image is verified to determine whether there are defects through image processing and analyzing module. The first image capturing module is arranged right above the LCD panel under test to complete capturing image with an angle of view vertical to the LCD panel. The second image capturing module is arranged at the side of the LCD panel, and a direction-rotatable reflective mirror is arranged along with the other opposed side. With the direction change of the reflective mirror, the second image capturing module can vary its detecting angles, thereby finding the defect types and positions of the LCD panel.
