CPI posts some updates on their OLED developments
The UK's Centre for Process Innovation (CPI) posted some updates on their OLED program. They have recently produced defect free OLED lighting samples. They managed to produce panels that has large (over 250 cm2) emissive areas (they are producing these panels on 8" substrates and so could exceed 160x160 mm panels).
The CPI developed two kinds of panels - the first uses small molecule materials and the second uses full solution-processable PLED materials. They have also produced samples that use a hybrid structure with a PEDOT layer (deposited using a slot die process) with an evaporative emissive layer (that has better efficiency and performance compared to the PLEDs). The 154x154 mm example shown above is the hybrid structure.
