POWER SUPPLY REDUNDANCY DEVICE FOR A DISPLAY SYSTEM

Abstract:

A system comprises a redundancy circuit board including a plurality of primary input connectors each connectible to a primary power supply that supplies primary electrical energy, a redundancy power input connector connectible to a redundant power supply that supplies redundant electrical energy, a plurality of output connectors connectible to a display component powerable by the primary or redundant electrical energy, and a plurality of electrical pathways including primary pathways each connecting a primary input connector to a corresponding output connector, redundant pathways each connecting the redundancy input connector to a corresponding output connector. The system also includes one or more electrical devices that detect whether primary electrical energy has been interrupted along a first primary pathway, activate the redundant power supply to supply redundant electrical energy to the redundancy input connector, and direct redundant electrical energy along a first redundant pathway to the first output connector.
