Description

【Technical field】

[0001] The invention relates to an organic light-emitting display, in particular to an organic light-emitting display with a pattern structure formed on the light-emitting surface of a light-transmitting layer, which has a high optical utilization rate. 【Background technique】

[0002] The research on organic light-emitting displays began in the 1980s. Ching.W.Tang and S.A.VanSlyke (Appl.Phys.Lett., 1987, 51, 913) of Kodak Corporation of the United States made a structure of ITO / Diamine / Alq by evaporation. 3 / Mg: Ag components (ITO is indium tin oxide, Diamine is diamine, Alq 3 Tris (8-hydroxyquinoline) Aluminum (Tris (8-hydroxyquinoline) Aluminum)); and in 1990, J.H.Burruges and others at the University of Cambridge also used PPV (poly (p-phenylenevinylene)) as the light-emitting layer to make A component with the structure ITO / PPV / Ca is obtained, see US Patent No. 5,247,190. Therefore, in the development of organic light-emitting displays, they can be di...
