Review Display Systems Opaque optical cover for front panel designs

The dead front effect (DFE) is a highly opaque optical cover glass for front panel designs. For equipment and systems using high-brightness TFT display modules with graphical user interfaces, implementing a DFE helps in creating a clean, uncluttered front panel. When integrated on to the top surface of a TFT display module, this design configuration creates a completely dark, black appearance. The “off” state TFT display is effectively completely hidden from view underneath an opaque cover glass. When the TFT display is switched to its “on” state, the display image can be seen clearly, and the viewing of information, graphics, text or images is unrestricted.
