HIGH CONTRAST THIN FILM ELECTROLUMINESCENT DISPLAY

摘要

A display system (25) includes an enhanced specularity multi-layer thin film electroluminescent (TFEL) panel (26) and circular polarizer filter (27) which combine to provide a high contrast TFEL display. The enhanced specularity is obtained by increasing the rate thc phosphor layer of the panel is deposited which results in a smoother, more specular surface. The increased specularity of the panel (26) provides a darker display background, and therefore higher contrast.
