IPTE has developed a flexible and powerful system for testing of complete LED panels. All relevant optical and electrical characteristics and parameters can rapidly, accurately and reliably be measured. The test system is designed for application in the manufacture of LED panels and especially verifies large panels with 300 or more single light-emitting diodes. Some of the key characteristics, which can be verified with the test system, are the LED brightness, the color spectra, forward voltage and the blocking-state current for each LED component in a panel.
The entire test cycle takes just 25 seconds. The LED test equipment can easily be reprogrammed for other LED types in the event of product changeovers.
