Description

WAA0213A2CNA6NXXX000 is a color electronic paper display module built on an active matrix TFT substrate, designed for applications requiring low power consumption and high contrast. The panel can display black, white, yellow, and red images, depending on the associated lookup table. Leveraging color epaper display technology, this technology provides exceptional reflectivity and ultra-wide viewing angles, ensuring clear and highly readable content, even in bright environments.

The integrated circuitry includes gate and source drivers, a timing controller, an oscillator, a DC-DC boost circuit, and memory to store the frame buffer and lookup tables. Additionally, circuits control VCOM and border settings, making this color epaper display ideal for outdoor, high-brightness, and portable applications, offering long-lasting, energy-efficient performance.
