New Color Models for Electronic Posters that Can Maintain Displayed Images with Zero Watts Power Consumption*1

EP-C251/C131 Color Electronic Paper Display (installation conceptual rendering)

Note: Screen images shown are simulated pictures. Actual display will differ.

Sharp Corporation will introduce new color models of its ePoster electronic paper displays that can maintain the displayed image while consuming no power (zero watts). Two sizes will be available: the 25.3-inch EP-C251 and 13.3-inch EP-C131 models.

These units feature the electronic paper technology of E Ink Holdings Inc.*2, the world’s commercial leader in the electronic paper field, now offering support for color displays. In addition to high visibility similar to printed paper and the ability to rewrite the display whenever necessary, the powerful graphic capabilities provided by rich color have been added to the display, greatly expanding the range of potential usage scenarios. Power is required only to rewrite the display, and once rendered, the displayed image can be maintained even if the power is turned off*3. In addition, these units are thin and lightweight, enabling easy mounting simply by hanging with a wire*4. They can be used in places where it has been previously difficult to install digital signage due to issues such as connection to a power source and load capacity. They can also serve as replacements for printed paper posters. They will prove useful for a wide variety of applications, including as location directories and informational signage as well as advertising displays in commercial spaces and retail stores, and to display menus in restaurants.

The content displayed can be easily updated using a USB flash drive and can also be rewritten via a smartphone app. Plus, when combined with e-Signage S, Sharp’s proprietary software system for content distribution and management (sold separately), the display can be updated over a network, making managing and operating the display smooth and easy, including updating content on multiple display units at one time, specifying the updating date and time, and more.

Sharp will continue to innovate information dissemination in the carbon-neutral era via ePoster, which achieves display image retention while consuming zero watts of power.
