Organic Light Emitting Displays

OLED (Organic Light Emitting Displays) are a new technology that uses organic materials to produce light. When thin layers of this material are sandwiched between appropriate anode and cathode layers, a relatively modest voltage (typically 2-10 volts) applied across the material will cause it to emit light in a process called electroluminescence. This combination of anode materials, cathode materials and light emitting organic materials forms an OLED. There are two essential types of OLEDs - small molecule (SMOLEDs) and polymer OLEDs (poly-OLED). While the essential operation of these two types are quite similar, there are differences in the process used to manufacture them. SMOLEDs use organic materials with a relatively small molecular structure. This material must be applied using sophisticated vacuum vapour deposition techniques. Poly-OLEDs use organic material s with much larger molecular structures, which allows simpler spin coating or printing techniques to be used to apply the organic layer.
