发明名称 Organic EL display device having host compound and phosphorescent luminous compound, and method of driving same
摘要 In an organic electroluminescence display device ( 30 ) comprising an organic EL element ( 26 ) having a structure wherein an organic luminescent medium ( 24 ) is sandwiched between a top electrode ( 20 ) and a bottom electrode ( 22 ), and a driving circuit ( 14 ) for driving the organic EL element ( 26 ), the organic luminescent medium ( 24 ) comprises a host compound and a triplet-related luminous compound and the driving circuit ( 14 ) applies a electric pulse voltage or pulse current having a frequency of 30 Hz or more and a duty ratio of 1/5 or less. In this way, it is possible to provide an organic EL display device which consumes a low electric power and has a long luminous life span, and a method for driving the same.
