ABSTRACT:
An AC TFEL device includes a front electrode set deposited on a transparent substrate and a rear electrode set, the electrode sets enclosing a thin film laminate which includes a pair of insulating layers sandwiching an alkaline earth thiogallate thin film phosphor doped with a rare earth activator. The thiogallate phosphor layer is capable of producing blue light of sufficient intensity to create a full color TFEL panel.
