Abstract

Full-color polymer light-emitting diode (PLED) arrays presently are mainly produced by ink-jet printing. Here, we report a new approach for fabricating full-color PLED arrays that takes advantage of the low-cost and high throughput spin-coating and photo-patterning processes. Compared to previous approaches that also employed photo-patterning, our approach does not require wet processing steps, and the spectra of the colors emitted are not sensitive to the photo-patterning time. Because the photo-pattering is a traditional technology which was proved to be successfully used in producing liquid crystal displays and other electrical productions, this method may provide a low-cost and high throughput procedure to manufacture polymeric flat-panel display devices.
