The Epson Broadsheet controller is used in many popular reading devices, such as the Kindle 2/DX, the Nook and the Sony PRS-600/900 (E-book Reader Matrix
). Epson now appears to be E Ink's initial partner for a color capable controller.

Further confirmation that color E Ink displays are on the way came today from Epson, which announced its new S1D13524
According to Epson, E Ink will offer an S1D13524 prototype kit "that will enable engineers to rapidly prototype and develop next-generation color e-paper products," though further details were not announced. In its statement, the company also quoted Hanvon Technology as saying it will launch a color e-reader by the end of this year, presumably using the S1D13524 and new screens from E Ink.
According to Epson, its S1D13524 will be sampling in June for $24. Production quantities will be available in December, the company says.
I would be surprised if we saw shipping color E Ink devices this year, but perhaps they will be available next spring.
