Polymer Vision's Readius device, which has a roll-out grayscale screen, is being . Telecom Italia Mobile is the first operator scheduled to release it, with a commercial launch set for the end of the year. Polymer Vision has not confirmed any discussions with U.K. operators.
The device's makers say that the touch screen, , "offers a readability similar to printed paper" with high contrast and high reflectivity. Future versions could include color and the ability to show moving images, the company said.
TIM's customers will be able to download newspapers and e-books for the device through their mobile-network SIM card. The Readius will offer Wi-Fi connectivity, a mini-USB port and "an optimized combination of cellular (EDGE/UMTS) and broadcast (DVB-H IP data-casting) mobile functionalities," the company said. The device also will work as a music player.
Because of, Polymer Vision said, the device will need to be charged only every 10 days on average.
According to Thomas van der Zijden, vice president of marketing at Polymer Vision, the company's initial production capacity for the Readius devices will be "a few hundred thousand," which he said was a "very small number" for the mobile industry. "It's a starting point and we can extend that capacity if needed," he said.
The cost of the device remains a secret for now, although van der Zijden insisted that LED displays were intrinsically cheaper to produce thanbecause they do not require backlighting. If economies of scale are applied during their manufacture, he said, the rollable displays could be competitively priced.
Van der Zijden also insisted that the new Readius was a major advance on its initial concept model, shown to the world in 2005. "That product was really an engineering laboratory type of product that showed it was possible, but the reliability and robustness of that display wasn't good enough for commercialization," he said on Wednesday, claiming that the new device performed better, was more reliable and could display 16 rather than 4 shades of gray.
"This black-and-white display should really be seen as a first step towards a world where every mobile device has a rollable display," said van der Zijden, who added that this would happen only when the displays could manage color and video, a development he puts at five years from now.
He also suggested that the displays would offer new opportunities for content publishers, operators and the advertising industry.
