Abstract
An assembly (16) for covering a visual display means (10) which has an array of pixels (12) is described. The assembly (16) comprises an array of cells (18) with reflective walls and an opening at each end. A transparent cover sheet (20) is positioned adjacent the open end of the cells (18) on one side of the array. The array is dimensioned such as in use each cell (18) is aligned with one pixel (12) of the visual display means (10). In this way, large visual display systems with excellent optical performance can be provided which can be used both internally and externally and are capable of bearing loads and forming structural members.
