A multi-channel OLED stress test system was designed and made. The system could simultaneously stress 512 OLED devices independently in constant current
constant voltage
or constant light intensity testing mode. The system has a wide range of testing conditions with output current from 0.02 mA to 100 mA
and output voltage from 0 to 24 V. The system adopts a modular design which could easily build 512
256
128
64
32 channels based on users needs. The application software built on LabVIEW development platform includes a user-friendly interface
and a self-protection feature from power failure
ensuring the continuity of the testing
and the safety of the data. With an environment chamber
the ambient temperature and humidity could be conveniently adjusted.
