Sharp EP-CA22 A2 E-Paper Full Color Display 13.3 inch ACeP

The Sharp EP-CA22 is an A2-sized full color e-paper display utilizing Advanced Color ePaper (ACeP) technology. With a 13.3-inch screen and 1600x1200 resolution, it delivers vibrant 7-color images (red, green, blue, cyan, magenta, yellow, black, white) without the need for a backlight. Its bistable nature retains the image even when power is removed, making it ideal for low-power signage, retail labels, and information displays.

Advantages

Ultra-low power consumption (only draws power during refresh), wide viewing angle >170°, and excellent readability in direct sunlight. The display is lightweight and thin, perfect for portable or wall-mounted applications. Integrated controller simplifies integration with Raspberry Pi, Arduino, or STM32 via 4-wire SPI interface.

Suitable for

• Electronic shelf labels (ESL)
• Digital signage for retail, museums, or offices
• Information boards (timetables, menus, maps)
• IoT devices requiring low-power displays
• Educational and prototyping projects
