E Ink Holdings has launched an on-cell touch ePaper module, which it says is the world's first. EIH's on-cell touch technology can be applied to the company's E Ink Carta monochrome displays and its Kaleido Plus color displays.
Most e-readers today add a touch layer onto the E Ink display. EIH says that the new technology will increase the contrast ratio by 30% compared to the standard added touch layer solution. For the Kaleido Plus displays, the on-cell will increase color contrast ratio by 40% and the color saturation by 15%. As an added bonus, the on-cell touch solution will be more cost effective and could help reduce eReader prices.
