The liquid crystal dropping apparatus includes a liquid crystal container in which liquid crystal is charged so that a pressure is applied to the liquid crystal if gas is supplied into the liquid crystal container, an opening and closing device for opening and closing a liquid crystal discharge hole provided at a lower end of the liquid crystal container, and a vibration energy supply device for supplying vibration energy to the interior of the liquid crystal container.
Abstract:
Disclosed are a test system and a test method using a virtual review, capable of driving a test device and reduce the number of operators by allowing an operator to perform review and determination 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 examination information related to the defect. A main server constructs the examination information from the test device as a database and transmits them to a review host. The review host determines whether a defect exosts on the array substrate or color filter substrate based on the examination information from the main server to yield a determination result and resends the determination result to the main server.
