The current status of thin‐film electroluminescence

— The current status of inorganic and organic electroluminescence (EL) is summarized. Emphasis is given to recent developments for full-color displays. Advantages and drawbacks of both technologies are discussed and possible fields of applications are identified. In the case of inorganic EL, the most important task is the development of an efficient blue material. Organic EL has to overcome stability problems if these technologies are to be considered for high-information-content full-color flat-panel-display applications.
