PURPOSE:To install a driver under specified normal temperatures and then execute an accurate test by installing an object to be tested in a test bath and an electrical driver within a normal temperature chamber and then forming the object to be tested and the drive so that they can be connected by a short wire. CONSTITUTION:A driver 3 of an LCD panel 4 is provided within a normal temperature chamber 2 and is connected to a power supply outside a test bath 1 by wiring L the driver 3. The panel 4 is provided at the front of a door 21 of the normal temperature chamber 2 and is wired L to the driver 3 within the corresponding normal temperature chamber 2 through a cable hole 21a of the door 21. Therefore, the panel 4 within the test bath 1 is maintained to be at a specified temperature and humidity, at the same time temperature within the normal temperature chamber 2 where the driver 3 is located is maintained at normal temperatures, current and signal are fed to the panel 4 from the driver 3, and then it is operated and environmental resistance of the panel 4 is tested. Since toe driver 3 is installed under specified normal temperatures, a test can be made accurately. |
