Plastic Logic opened the doors of it's Cambridge lab on 27 June, to give journalists and analysts an insight into some of its research and development projects. As well as demonstrating the world's first colour flexible plastic display with video rate driven by organic thin-film transistors (OTFTs), the company was also keen to show off some of its other innovations, including, transmissive backplanes, ultra-thin form factors and plastic displays embedded with silicon chips.

Optimising text clarity
One of Plastic Logic's key research areas is around optimising text clarity. The standard displays have a resolution of 150ppi (pixels per inch), but the company has developed screens with a 225ppi backplane. The conventional displays have about 1 million organic transistors, supporting about 6 pixels per millimetre; the new displays have about 3m transistors and about 9 pixels per millimetre. While this makes little difference for Latin characters, a higher resolution can be essential when reading Kanji or Chinese characters with a small font size. It also helps improving colour.
