Abstract
A method, system and apparatus for dynamically monitoring and calibrating display tiles are provided. The apparatus comprises: an array of light emitting devices; one or more light emitting devices paired with light emitting devices of the array; one or more sensors configured to detect an optical characteristic and/or an electrical characteristic of the one or more paired light emitting devices; and, circuitry configured to: drive the array; drive each of the one or more further light emitting devices under same conditions as light emitting devices of the array; temporarily drive each of the one or more paired light emitting devices under different conditions from the array; and, adjust driving of the array based on the optical characteristic and/or electrical characteristic of the one or more paired light emitting devices detected at sensor(s) when the one or more paired light emitting devices are driven under the different conditions.
