Abstract

A shading device is described for use with a display system. The shading device includes a first component, typically a rigid component, and a second component. The second component at least partially covers the first component. The second component is a solid continuous film which has a lower reflectivity than the first component. In a particular embodiment, the second component is more elastic or flexible than the first component and/or has a hardness smaller than the first component, and is furthermore adapted such that it can provide a sealing contact with a plurality of light sources. The latter allows using the shading device also as a sealing arrangement for sealing electronics and other components of the display system from the ambient of the display system.
