Abstract
Electromagnetic Interference (EMI) shields for a direct-view display having a direct-view display panel and an outer panel that provides an outer surface for the direct-view display. These EMI shields include a conductive mesh having an array of gaps therein. The conductive mesh is configured to shield at least some of the EMI that is emitted by the direct-view display panel. An optical redirecting structure is also included, that is configured to redirect at least some optical radiation that is emitted from the direct-view display panel that would strike the conductive mesh, through the gaps in the conductive mesh. The EMI shield is configured to mount between the direct-view display panel and the outer panel such that the optical redirecting structure is adjacent the direct-view display panel and the conductive mesh is remote from the direct-view display panel.
