Apple’s Retina Display that debut on the iPhone 4 really made headlines, and till now nobody managed to take down Apple’s throne in terms of mass products with such display. Samsung and LG did demonstrate a few high pixel density LCDs, and Toshiba managed to develop a 367ppi display for smartphones. However, not many are in mass production.

Now, E Ink Holdings and Epson will do something for the fans of ePaper and e-Reader, as E Ink Holdings and Epson have just announced the co-development of a 300ppi ePaper display. To be exact, E Ink will be in charge of producing the sharp-looking 9.68-inch 2,400 x 1,650 display panel, whereas Epson will take care of the high-speed display controller platform to go with E Ink’s part.

Of course, the technology is still in its early stage at the moment, so no availability has been announced just yet.
