Electro-luminescent display e.g. for imaging functional symbology of operator unit, includes additional unit based on electro-luminescent layer positioned between two switched electrodes

摘要: Electro-luminescent displays based on a unit (3) having an electro-luminescent layer (EL1,EL2) arranged between two switched electrodes (E1,E2) are generally designed to provided high degree of functionality and variable color display, without incurring excessively design development costs. The display (1,4) is with at least one further consisting (EL2,EL2') (E2,E3). units (2,3) over the other form layered body, but (4) which corresponds in its arrangement (1) has layers (EL1', EL2') mutually offset chess-board manner.
