The advance has been achieved in Plastic Logic’s transistor matrix backplane, with the new displays using the same Eink overlay as the company’s previous displays. Further image improvements can be expected when using the latest e-paper technology. Prior to this technology breakthrough Plastic Logic’s most advanced commercially available display was 196ppi in a 4.7-inch form factor.
Plastic Logic’s 500ppi displays makes written text much sharper which is an advantage for Chinese and Japanese where detail has previously been lost due to resolution limitations. Another use case benefiting from the improved display density would be applications where accurate lines and measurements are critical, such as ePaper rulers, portable mapping or CAD drawings.
Tim Burne, CEO of Plastic Logic, commented: “Our flexible OTFT driven EPDs have so many fantastic advantages over traditional glass displays, in terms of their power consumption, daylight readability, etc. but one of the perceived limitations of the technology has always been the display density. With our new 500ppi display capability we’re not only breaking through that barrier and giving ourselves a real competitive advantage but also creating a real opportunity to widen the potential appeal of ePaper technology."
