System Features

Description of Driving Power Supplies:

1. Total 100 stations, each equipped with two types of power supplies to support testing of two different products.
2. 8-channel independent power supply FS-P8CH: voltage output 0-20V, current output 0~18mA.
3. 8-channel independent power supply FS-P8CH-BIG: voltage output 0-20V, current output 0~200mA.
4. The two types of power supplies can be used for mixed testing across the 100 stations without designated station numbers.
5. Both power supplies provide independent interfaces, facilitating the design of downstream current boards.

OLED Device Lifetime Testing Software

Adopting a split front-end and back-end architecture: the front-end is responsible for data viewing and measurement condition setup, while the back-end controls program operation and log recording. During measurement, operation on the front-end interface achieves complete smoothness without lag, and the software responds quickly.
