Epson declares inkjet tech enable to print OLED

Epson has recently made the announcement of its development of inkjet technology to enable uniform printing of organic light-emitting diode (OLED) displays that would make the next-generation big-screen TVs closer to reality. Overcoming the uneven distribution of the organic materials was the last major obstacle hindering the production process; now the only tasks remaining are improving the lifetime of the materials and lowering production costs.

Unlike the inert liquid crystals that form the images on LCDs, the organic materials of OLED displays emit light directly when an electric current is passed through them. So there is no need for expensive backlighting like in LCDs. This significantly reduces the component cost of making the display and just as importantly in this era of concern over the environment.
