ABSTRACT:
A method forming a flexible EL device comprising the steps of:1) forming the non-adhesive shield polymer layer (2) on the plastic film layer (1);2) forming a back conductive electrode layer (3) on the non-adhesive shield polymer layer (2);3) forming dielectric layer (4) comprising a mixture of high-dielectric constant powder and binder on the back conductive electrode layer (3);4) forming first field polymer layer (5) on the dielectric layer (4).5) forming a phosphor layer (6) comprising encapsulated phosphor and binder on the first field polymer (5);6) forming second field polymer (7) on the phosphor layer (6).7) forming the transparent electrode layer (8) by using conductive polymer comprising transparent conductive materials on the second field polymer layer (7);8) forming a polymer protection layer (9) on the transparent electrode layer (8); and9) then separating the EL cell (2–9 layers) from plastic film.
