Test apparatus having auto probe that contacts a display device and test method using the same |
摘要 |
A test apparatus having an auto probe and a test method using the same reduces difficulties in defect detection which are caused by a manual test by operators. The test apparatus includes an auto probe unit that contacts a panel of a display device. A test pattern is input to the panel. A vision unit installed above the panel collects a pattern displayed on the panel. A computer system analyzes and determines information about the collected pattern. Whereas the panel was previously tilted from a horizontal position and then examined by the operator manually, in the present test method a movable camera installed at an auto probe apparatus permits testing while the panel is in the horizontal position. |
