Abstract. Recently developed ac ZnS-powder electroluminescence (EL) devices have flexibility (thickness is about 60 µm) and can be multisegment, multicolor, as well as rolled and bent. All colors (white, blue, blue-green, green, and orange) have been investigated for improvement of their operational characteristics. Many factors including the type of phosphor, formation method, contacts, initial input power (peak voltage and frequency), type of input power, and environment safety which define the panel's properties are discussed.

Keywords: electroluminescence, thick film display, powder, phosphor, flexibility.
