SYSTEMS AND METHODS FOR TESTING MULTI-ELEMENT LIGHTED DISPLAYS
First Claim
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.

Abstract
Systems and methods for testing a light emitting display unit having a plurality of light emitting elements are disclosed. Embodiments include a system with a test module, the test module including a plurality of light detection elements. Each of the plurality of light detection elements may generate a signal upon detection of light emitted from a light emitting element. The test module may also include a circuit. The circuit may receive input signals from the plurality of light detection elements, process the input signals based on a pre-determined function of the circuit, and generate an aggregate output signal based on the processing of the input signals. The circuit may also process the input signals based on discrete implementation of a combinational logic. The circuit may further receive instructions determining the combinational logic to be implemented.
