Apparatus for testing liquid crystal display panel
An apparatus for testing a liquid crystal display (LCD) panel which is capable of easily attaching or detaching a large polarizer to/from a test board when testing a large LCD panel, the apparatus comprising a test board for outputting light to an LCD panel which is placed thereon, a polarizer fixing unit rotatably formed at the test board and having a groove in which a polarizer is inserted, and a stop formed at the test board to fix the polarizer fixing unit to a desired position.
1. An apparatus for testing a liquid crystal display (LCD) panel comprising:
a test board to transmit light to an LCD panel that is placed thereon;
a polarizer fixing unit rotatably formed at the test board and having a groove into which a polarizer is insertable; and
a stop formed at the test board to fix the polarizer fixing unit at a predetermined position.
2. The apparatus of claim 1 , wherein the polarizer fixing unit is rotatable to position the groove substantially perpendicular to a ground.
3. The apparatus of claim 1 , further comprising a fixing member installed at one of the polarizer fixing unit and the stop to fix the polarizer fixing unit.
4. The apparatus of claim 3 , wherein the fixing member includes a magnet.
5. The apparatus of claim 1 , further comprising a camera disposed at an upper portion of the test board to capture the LCD panel to determine an aligned state of the LCD panel.
6. The apparatus of claim 1 , further comprising a jig insertable into the polarizing fixing unit to support the polarizer.
7. The apparatus of claim 1 , further comprising a rotational shaft to rotate the polarizer fixing unit.
8. An apparatus for testing a liquid crystal display (LCD) panel comprising:
a test board to transmit light to an LCD panel that is placed thereon;
a jig to support a polarizer; and
a polarizer fixing unit formed at the test board and having a groove into which the jig is insertable to fix the polarizer,
wherein the polarizer fixing unit is rotatable to an angle at which the groove is perpendicular to a ground to thus insert the jig into the groove.
9. The apparatus of claim 8 , further comprising a rotational shaft to rotate the polarizer fixing unit.
10. The apparatus of claim 8 , further comprising:
a stop for stopping the rotation of the polarizer fixing unit; and
a fixing member for fixing the rotated polarizer fixing unit.
