Product Overview
This 2.8 inch 6-color electrophoretic display module is developed for embedded products that require low power consumption, stable static image display, and good readability in ambient light. With a 300 × 400 resolution and active matrix design, it is suitable for showing text, icons, labels, user interface elements, device status, and fixed graphic content in portable and compact electronic systems.
Because the module uses bi-stable E-Paper technology, the image remains visible without continuous power after refreshing. Compared with conventional LCD solutions, this helps reduce battery load in products that display information for long periods without frequent screen updates. At the same time, the 6-color display capability allows richer content presentation than standard black and white E-Paper modules.
Its compact size, reflective structure, SPI communication support, 6-color display capability, and low-power operation make it suitable for smart labels, portable terminals, handheld devices, industrial instruments, IoT products, and custom OEM or ODM embedded display projects.
