Abstract: A method for testing a display module may include providing light to the display module, obtaining an image of the display module, measuring a first center of a hole in the display module, measuring a first distance from the first center to an edge of the hole, measuring a second center of a closed line formed by a signal line of the display module, measuring a second distance from the second center to the signal line, calculating a third distance between the first center and the second center, and comparing the second distance with a sum of the first distance and the third distance.
