Title: FABRICATION OF FLEXIBLE HYBRID LOW MOLECULAR WEIGHT COMPOUND POLYMER LIGHT EMITTING DEVICE BY SCREEN PRINTING
Keywords: film deposition, flexible displays, organic light emitting devices, screen printing.

Abstract: It is demonstrated successful fabrication of simple bicomponent single layer OLED produced by screen printing. The device exhibits high mechanical stability after 400 cycles of bending. Turn on voltage of 5 V and maximum brightness of 92 cd/m2 is achieved at current flow 2.9 mA. Luminous efficiency is higher than the reported for similarly produced devices, reaching 3.94 lm/W and the power consumption is average 50 mW - very suitable for portable devices with battery power supply. Another advantage of the thick film technology is the higher thermal stability when operates at maximum possible voltage of 30 V for several tenth of hours. It is due to the more efficient heat dissipation from 2 μm thick organic coating in comparison with the thin ones (hundreds nanometers).
