摘要:
An organic light emitting device (OLED) has a thick (100 to 250 nanometers) porphyrin buffer layer between the anode and the luminescent region. The thick porphyrin buffer layer in the OLED results in a small increase in device operating voltage, reduces the possibility of OLED shorting and can improve color purity in blue emitting OLEDs due to its significant optical absorption in the red range.
摘要:
An organic fight emitting device (OLED) will have multiple capping layers on an electrode to provide a passivation region to prevent formation of dark spots. The passivation capping layers are, in sequence from the electrode, a first dielectric material layer, a metal or metal alloy layer with a work function of less than 4 eV, and a second dielectric protective layer.
