Patent ID: 7548083

Claim:
A test apparatus having an auto probe, comprising: an auto probe unit having a plurality of gate needles and data needles configured to facilitate electrical communication with a plurality of corresponding contacts on a panel of a display device; the auto probe unit configured to input a test pattern to the panel performed by arbitrarily supply voltage to the gate needles and the data needles, wherein the auto probe unit performs a test for determining whether or not the panel has a defect in appearance or an electric defect before a module process of connecting a driving circuit for driving the panel; a supporting member provided with the auto probe unit thereon; a vision unit installed above the panel configured to collect data corresponding to a pattern of the visible light displayed on the display device, wherein the vision unit comprises a vision apparatus that scans the panel in a horizontal direction and collects the pattern displayed on the panel during the test, wherein the vision apparatus operates within a plurality of predetermined angular ranges including 0 to 70 degrees, 80 to 100 degrees, and 110 to 160 degrees during the test to provide complement defect detection varying according to the viewing angle of the panel and wherein the panel is loaded onto the supporting member in a conveyor logistics system and the test is performed in a horizontal direction using the vision apparatus; a computer system in communication with the vision unit configured receive the collected data from the vision unit and to analyze the data to determine if a defect exists; and the computer system configured to control movement of the vision unit in horizontal direction relative to the panel and in a tilting direction relative to the panel.
