Disclosed are a test system and a test method using a virtual review based
on a captured image of a defect on a substrate. The test system using a
virtual review comprises: a test device that takes an image of a defect
on an array substrate or color filter substrate to acquire a captured
image and provides an information an related to the defect. A main server
stores the captured image and the information related to the defect from
the test device at a database and transmits them to a review host. The
review host determines whether a defect exists on the array substrate or
color filter substrate based on the information related to the defect
from the main server to yield a determination result and resends the
determination result to the main server.
