1. A system for testing a light emitting display unit having a plurality of light emitting elements, the system comprising:

  • a test fixture, including;

    a plurality of light detection elements, the light detection elements being configured to generate signals upon detection of light emitted from the light emitting element, wherein the test fixture is movable towards or away from the light emitting elements to maintain a pre-determined distance between the test fixture and one or more of the light emitting elements based on an intensity of the generated signals; and

    a circuit configured to;

    receive input signals from the light detection elements;

    process the input signals based on a pre-determined function of the circuit and discrete implementation of a combinational logic, wherein the pre-determined function includes determining wavelength of the light emitted from the light emitting elements; and

    generate an aggregate output signal based on the processing of the input signals, wherein the aggregate output signal is configured to determine whether the light emitting display unit is functioning.
