Advances and prospects of thin film phosphor for high resolution field emission displays

Abstract

With the development of electronic displays becoming flat and portable, field emission displays (FED) get the widespread attention because they have the advantages of flat-panel displays and CRT displays together. At present, as one of the core components in FED, the screen is still the short board in the application of FED. With thin film phosphor as the phosphor layer, the screen will be very beneficial to the application of FED because of many advantages of extremely high resolution, strong adhesion, good smoothness, low release of gas, good conductivity and so on. That highlights the important application value and research significance of thin film phosphor in FED. In this review, we summarize the recent advances in the thin film phosphors for FED with emphasis on the film materials, preparation technology, and the main problems in the film. And the further study of thin film phosphors in FED is also presented.
