Supply of cold tablets with a conductive silver paste, cold tablets, also known as EL sheet, is a convert electrical energy to light the device, compared with other light products, EL sheet weight of clean, thin, flexible, flexible. Silver can be used in which EL backlight (EL sheet, EL sheet, EL sheet), the ITO conductive film, PET, and ITO glass can be used with good printability, conductivity, resistance to oxidation resistance, hardness and adhesion, with different dielectric layer of barium paste and powder layer with a good light.
