Understanding the display
Your SmartBand Talk features an E Ink® display that uses electronic ink technology to reproduce the appearance of ordinary ink on paper. In an E Ink® display, no backlight is used. Instead, ambient light from the environment is reflected from the surface of the display, making it more comfortable to read. The image on your E Ink® screen is retained even when power to the screen is turned off. Also note that when the content displayed on the screen changes, there is a brief transition time. This is normal E Ink® display behavior.
