The future of display production is here with inkjet printing of OLED panels. Konica Minolta has announced the first commercial printhead for OLED panel production, available this spring.<br /><br /><h3>Printable OLED panels</h3>A few years back the industry started talking about printing large and small OLED panels with a inkjet printer that releases small drops of OLED material on a glass or plastic layer. This is now possible with Konica Minoltaâ€™s first commercial inkjet printing head that will be available to display makers this spring.<br /><br /><p align=center><img class="imgresponsive" src=pictures/konicaminoltaprinthead.jpg><br><i>Konica Minoltaâ€™s new printhead can print OLED panels in quantities</i></p><br />The printhead is only 38 mm wide and has 128 nozzles in one row. This makes it extremely precise and it is possible to achieve 1 picoliter drops (1 picoliter is a trillionth of a liter). Konica Minolta hopes to sell the product to existing and new display makers.<br /><br />It basically means that manufacturers can take a glass or plastic substrate and then use the printhead to apply the OLED material used for creating small pixels.<br /><br />Another company called Dupont, believed to <a href=http://www.flatpanelshd.com/news.php?subaction=showfull&id=1327926619><b>be a Samsung-partner</b></a>, is also developing inkjet printing methods for OLED panel production. They even claim that large-size OLED panels can be produced at lower costs than LCD panels in for example 50-inch sizes. According to industry sources, Dupontâ€™s OLED printing technology is not optimized on the sub-pixel level, however. Each pixel on a display panel requires three sub pixels in red, green blue (RGB) to form one pixel.
