Large Format Display (LFD) are flat screens designed to display information, messages, advertisement and presentations. LFD's are designed for applications with high performance and durability requirements. Innovation in technology and fabrication have made displays more affordable. Currently the latest life style and the eye catching style of communicating information to enhancing ambience, large format displays are the ideal solutions to any control room, retail store, shopping malls, lobby, or other professional applications. Interfaces, simplified remote scheduling maintenance, intuitive features have made large format displays more competitive over other type of displays. There has been a tremendous movement from earlier used visual displays such as cathode florescent lamps to latest light emitting diode. LED's unlike cathode florescent lamps does not have light filaments which does not burns and hence panels remains cool. In semiconductor material, when electrons move, the LED's are illuminated.
