Light emitting diode color resolution testing

A system for testing a color of light emitted by a light emitting diode (LED) device, the system comprising:

• a filter unit comprising at least a first filter and a second filter;
• a sensor;
• and
• a controller configured to select from the first filter and the second filter for testing the light from the LED device, the testing comprising:
• driving, by the controller, the filter unit to filter the light from the LED device using the first filter;
• and
• in response to the 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;
• in response to the sensor not receiving the measureable signal because of the second filter, outputting an indication that the LED device is rejected;
• and
• in response to the sensor receiving the measureable signal, outputting an indication that the LED device is of a color representative of the second filter.

A computer program product for testing a light emitting diode (LED) device, the computer program product comprising a memory device with computer executable instructions therein, the instructions when executed by a controller test the LED, the testing comprising:

• driving, by a controller, a filter unit to filter a light from the LED device using a first filter;
• and
• 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;
• in response to the sensor not receiving the measureable signal because of the second filter, outputting an indication that the LED device is rejected;
• and
• in response to the sensor receiving the measureable signal, outputting an indication that the LED device is of a color representative of the second filter.
