Photolithographic Patterning Method for Full Color Polymer Light Emitting Diodes |
| 초록 |
We have studied a photolithographic patterning method for polymer light emitting diodes (PLEDs). Blue light emitting polymer based on polyfluorene, which can be cured photochemically to yield an insoluble form, have been synthesized using Ni(0) mediated Yamamoto polymerization. The relationship between patterning property and several variables such as the exposure time of UV light, and the baking temperature and time, has been studied by using optical microscope analysis, UV/visible spectroscopy, and photoluminescence. Using the optimized patterning process, we have successfully fabricated the patterned blue PLED. Moreover, using the blue and the orange light emitting polymer, multicolor PLED has been also fabricated. In this presentation, the full color PLEDs by photolithography will be discussed in detail. |
