DESIGN OF CONJUGATED POLYMERS FOR ORGANIC LIGHT EMITTING DIODE

Abstract

One of the most promising ideas of the Light-emitting diodes (LEDs) technology is the use of the π-conjugated polymers. Light-emitting diodes (LEDs) promises superior performance in brightness and color resolution, wider viewing angle, lower power consumption, a thin aspect ratio and better physical characteristics. The advantages make OLED display attraction for the next generation mobile flat penal display (FPD). Polymer Light Emitting Diodes have a good chance to become the main display system in the near future since diodes have many advantage concerning preparation and operation over other display system. The emissive color of a π-conjugated polymer is fine-tunable by controlling the effective π-conjugation. Electroluminescent efficiency can be improved by balancing the hole/electron mobility through chemical modifications like incorporating electron-donating or electron-withdrawing groups with in the polymer backbone or the side-chain. Regarding with device fabrication, a polymer...
