ABSTRACT
Inkjet printing (IJP) is on the rise to become a competitive production technology for organic light emitting diodes (OLEDs). Recent progress in with drop volumes down pL regime as well constant performance improvements from material point of view have opened way towards IT displays. Here target resolutions are 250 ppi and beyond. For this purpose, small molecules highly suitable due their low impact ink viscosity excellent device performance. Their current status reviewed based bottom top emission. latter, crucial factors high like film uniformity precise thickness control discussed.
