Abstract
Disclosed is a system for testing liquid crystal and end seal of liquid crystal displays. In the present invention, a test unit P for liquid crystal distribution is disposed at a side of a loading unit L. The test unit P for liquid crystal distribution is disposed orthogonal to a test unit G for end seal. Unloading units Ug, Ur, Uj of good, repair, reject are disposed in parallel by a selected distance. A robot unit R one by one to the respective testing units, is disposed between the loading and unloading units L,U. An operating panel S is installed between the test units P,G according to the test result and a monitor M displaying the liquid crystal injecting hole is installed at the operating panel S. Furthermore, the investigator may conduct two tests for liquid crystal and for end seal simultaneously at one position in front of the operating panel S.
