Problems solved by technology

[0009] Because the organic light-emitting display has the characteristics of wide viewing angle, as shown in the third figure, α1, α2, α3 and α4 are the refraction paths of the light emitted from the light-emitting point Y, and the maximum viewing angle of the light emitted from the light-emitting point Y is θ1. About 180 degrees; but for display devices, the viewing angle requirement is only 160 degrees at most; therefore, light exceeding 160 degrees is wasted, resulting in low optical utilization of organic light-emitting displays

Abstract

The invention relates to a organic luminous display with design structure on light-out surface of light-penetrated layer, which comprises a light-out foot layer, a light-penetrated layer formed on said foot layer with a light-out surface, a prism film on said light-out surface with a plurality of prisms to reduce emergence angle of mergence light and collect light in effective visual angle. This invention can improve optical utility of display.

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...
