It is mainly used to detect the LED backlight FPC of mobile phones, tablet computers, etc., as well as the assembled backlight products.
2. Features _
1. Configure a high-precision program-controlled power supply module;
2. Adopt embedded processor to improve test accuracy and stability;
3. Quickly and accurately detect dead lights, dim lights, broken lights, half of a single light, etc. in each string of lamp beads;
4. Compare the voltage difference and current difference between each string of lights to reduce the electrical difference between each string of lights in the backlight. The range can be set according to requirements.
