2.9 inch e-Paper Module 4-colors for ESL Systems - RAA0290A2CNA8NXXX000 - Raystar

2.9-inch e-Paper Module 128x296 4-colors SPI Interface

Model No. RAA0290A2CNA8NXXX000

The RAA0290A2CNA8NXXX000 is a 2.9-inch e-paper module with 128x296 pixel resolution, designed for crisp black, white, red, and yellow imaging. This 2.9-inch e-paper display offers high contrast, strong reflectance, and operates in a purely reflective mode, ensuring excellent readability under ambient light. Its ultra-wide viewing angle, ultra-low power consumption, and bi-stable characteristics make it an optimal solution for Electronic Shelf Label (ESL) systems and other portable applications.

Built on electrophoretic technology, this 2.9-inch e-paper module integrates a gate driver, source driver, timing controller, oscillator, DC-DC converter, SRAM, LUT, and VCOM. The 2.9-inch e-paper features on-chip RAM with waveforms stored in OTP, along with SPI and I2C master interfaces for communication, and a built-in temperature sensor for stable operation. Its hard-coat antiglare layer enhances durability, supporting reliable performance across commercial temperature ranges.
