Micro-cavity Organic Light-emitting Device Design And Production

Organic light-emitting device(OLED) has become hotspot in the research of display field, which is regarded as the most competitive display in the future because of some special merits.Optical microcavity arouses great interest in condensed state physics. It can change characters of spontaneous emission, such as spectral full width at half-maximum, light intensity at peak and so on. In order to realize full color display and improve luminous efficiency, OLED with microcavity is formed. This paper introduces researching status of OLED, the basic principle and application of microcavity. It is found that microcavity not only is a good way for full color display, but also affect optoelectronic industry deeply.This paper states design approach, computing process and result of microcavity organic light-emitting device(MOLED). Theoretical analysis shows: compared with OLED, MOLED with Alq3 as light-emitting layer can emit different wavelength light by modulating length of cavity, spectral full width at half-maximum of MOLED changes from 100nm to 10nm~20nm and the light intensity at peak is increased by about 20 times, and luminous efficiency can be enhanced.OLED and MOLED are made with heat evaporation. In making MOLED, metal film substitutes dielectric films and anode according to technical conditions.Last, based on experience, two new MOLEDs are brought forward...
