The 4.2-inch E-Paper display offers a 400 × 300 pixel resolution (≈120 DPI), delivering sharp and readable visuals for embedded and IoT applications. Its bistable technology retains the displayed image without continuous power draw, making it ideal for ultra-low-power, battery‐operated, or HMI devices. With support for standard, wide-temperature and fast-update versions, the monochrome model accommodates environments from -20 °C to +60 °C or beyond. Equipped with optional mono and colour (BWRY) film types, this module is versatile for shelf labels, smart tags, industrial indicators and more offering long-term supply reliability and design continuity.
