LIGHT EMITTING DIODE COLOR RESOLUTION TESTING

Technical solutions are described for testing a light emitting diode (LED) device. An example method includes driving, by a controller, a filter unit to filter a light from the LED device using a first filter. The method further includes, in response to a sensor not receiving a measurable signal bec...

Zusammenfassung:Technical solutions are described for testing a light emitting diode (LED) device. An example method includes driving, by a controller, a filter unit to filter a light from the LED device using a first filter. The method further includes, in response to a sensor not receiving a measurable signal because of the first filter, driving, by the controller, the filter unit to filter the light using a second filter. Further, in response to the sensor not receiving the measureable signal because of the second filter, the method includes outputting an indication that the LED device is rejected. Further, in response to the sensor receiving the measureable signal, the method includes outputting an indication that the LED device is of a color representative of the second filter.
