The Design And Manufacture Of Top-emitting Organic Light-Emitting Devices

Organic Light-emitting Devices (OLEDs) have attracted intensive interests in the fields of science and industry for the merits of light weight , low cost , broad visual angle , fast response speed , active emitting , high brightness , high efficiency , availability for full color display , etc . The research works in this field gained rapid development especially since 1987,C.W.Tang for the first time reported the high brightness OLEDs at low operating voltage.In recent ten years, OLEDs have become a project on the cutting-edge of scientific research that relates to many intercrossed branches of science and advanced technology. Most of Organic Light-emitting Devices (OLEDs) use glass as the substrate, and all the structures of the devices are substrate emitting so far. Top-emitting organic light-emitting devices (TOLEDs) now are being a focus in the filed of OLED, since they are capable of achieving monolithic integration of an OLED displays, fabricating OLED displays for higher display quality yet without sacrificing aperture ratios of pixels and suitable for making microdisplay on silicon。This paper is focus on how to make a TOLED based with high brightness and efficiency at low voltage through. We use Ag as the anode and calculate the layer thickness through microcavity effects.An efficient top-emitting organic light-emitting devices (TOLEDs) based on silicon can be realized as follows: Firstly, a low turn-on voltage. That a material with a lower Ionization Potential than that of hole-transporting materials (NPB) is used as a hole-injection layer is an...
