Applications for the yellow tri-color e-paper displays include shop shelf labels, where yellow can be used to draw attention to special offers and price reductions. Shipping tags can incorporate yellow to highlight priority items. Corporate identification and access control badges often use one color for employees, another for contractors and another for visitors. EPDs enable these cards to be digitized, to include the person’s name and other details, with yellow EPDs used for one group, and black-and-white, or black, white and red EPDs for others.
Available in 1.54, 2.13, 2.66, 4.20 and 4.37-inch models, these active-matrix displays include an internal timing controller (Tcon), which minimizes the amount of programming and peripheral circuitry required. The displays’ high pixel-density (ranging from 111 to 140 dpi, depending on the screen size) and state-of-the-art driving waveform, deliver exceptional image quality and the ability to display intricate patterns precisely. Because key capabilities are pre-programmed into the display, those can be driven without consuming resource from the host controller.
