Samsung e-paper display
Earlier this week in Korea, Samsung demonstrated a working e-paper display, or more accurately, a color active matrix electrophoretic display (EPD) and the world's first to use carbon nanotubes. At 14.3 inches, it is among the largest e-paper displays in existence. Developed in conjunction with Unidym, which created the carbon nanotubes for the prototype, the display is energy-efficient and doesn't require backlighting while remaining highly visible under direct sunlight. As with other e-paper displays, images are retained on the screen without requiring energy to constantly refresh it.
