Abstract
Assemblies for enhancing the optical quality of electronic images displayed at an electronic display layer are provided. At least one optical sheet is located adjacent to the electronic display layer within a housing. A number of tensioning subassemblies exert tensioning forces on the optical sheet. A first component of each tensioning subassembly is attached to a location along a perimeter of each optical sheet and a second component is connected to the first component and the housing.
