摘要
In the manufacturing of screens for advanced displays, layers of small (1 to 10 mu m diam) luminescent particles may be deposited by electrophoretic deposition (EPD). A set of processing variables that enhance the adhesion strength of EPD phosphor deposits has been determined. Postdeposition baking at 425 degrees C for 1 h, addition of water or glycerin and use of Y(NO3)(3) instead of Mg(NO3)(2) in the deposition bath, and control of the particle size distribution can each enhance the adhesion strength of EPD phosphor deposits. When screens were excited by electron bombardment, the chromaticity was unchanged and the brightness was only slightly reduced by these processing conditions.
