A display comprises: a single-view image display panel ; and a parallax optic disposed over a display face of the image display panel for restricting the angular spread of light output from the display face of the image display panel. Said invention also relates, in particular to a galenical system which is embodied in the form of lipidic solid particles and strictly hydrophobic and devoid of water, surface active agents, emulsifiers, solvent traces and which is characterised in that it comprises at least one type of hydrophobic wax and at least one type of fatty non-neutralised acid. According to one embodiment, the method can further include depositing a second metal-containing layer onto the sputter etched first metal-containing layer prior to depositing the conformal Ru layer. In response to the health information indicating the first processor has failed, the processor ID controller sets the second processor as the default boot processor and the baseboard management module enables the multiplexer to switch to the second processor.
