While investigating polymer light emitting diodes (polymer-LEDs) fabricated by solution process, surface roughness
influences electro-optical (E-O) characteristics. We expect that E-O characteristics such as luminance and power
efficiency related to surface roughness and layer thickness of emitting layer with poly-9-Vinylcarbazole. In this study,
we fabricated polymer organic light emitting diodes by solution process which guarantees easy, eco-friendly and low
cost manufacturing for flexible display applications. In order to obtain high luminescence efficiency, E-O characteristics
of these devices by varying parameters for printing process have been investigated. Therefore, we optimized process
condition for polymer-LEDs by adjusting annealing temperatures of emission, thickness of emission layer showing
efficiency (10.8 cd/A) at 10 mA/cm2. We also checked wavelength dependent electroluminescence spectrum in order to
find the correlation between the variation of efficiency and the thickness of the layer.
