WAA0290A2CNA8NXXX000 is a 2.9" Electronic Paper Display (EPD). The display is capable of displaying black, white, yellow, and red images depending on the associated lookup table used. The 2.9-inch active area contains 128×296 pixels. The circuitry on the panel includes an integrated gate and source driver, timing controller, oscillator, DC-DC boost circuit, memory to store the frame buffer and lookup tables, and additional circuitry to control VCOM and BORDER settings.
