Abstract

AbstractWe present investigations on a new red emitting dye RedATDB. Doping small concentrations of RedATDB in an Alq3 host leads to red OLEDs (x=0.650, y=0.346) with good efficiency values (4.3 cd/A; 2.1 lm/W @ 100 cd/m2). To test our material for display applications, we produced monochrome red passive matrix displays (32 × 100 pixels). With appropriate display measurement equipment we investigate the pixel resolved electrical (I‐V) and optical (luminance) characteristics. Homogenous pixel performance data in terms of luminance and driving voltage has been observed.
