Organic light emitting diode (OLED) and display device
2013
The invention provides an organic light emitting diode (OLED) and a display device. The OLED comprises a substrate and at least one organic light emitting unit formed on the substrate; the outer-layer emergent surface of the organic light emitting unit is a convex curved surface. By the scheme, the outer-layer emergent surface of the organic light emitting unit is designed into the convex curved surface, a phenomenon that light emitted by the light emitting unit is totally reflected due to low refractivity in the transmission process can be effectively reduced, the light is limited in each structural layer, and the light intercepting rate can be improved, so that the utilization rate and brightness of the light are improved, and the problem that an OLED is low in brightness is solved.
