  • Description

3.5" 4-color E-Ink Display

This 3.5" ePaper doesn't just update labels – it commands the shelf in black, white, red, and yellow. At 121.7 DPI, every pixel delivers razor‑sharp contrast that cuts through store lighting and industrial glare. It refreshes in just 20s (12s partial), yet draws zero power once static – so your product outlasts its battery. Slim at 1mm, SPI‑ready, and fully self‑contained with on‑chip power, temperature sensor, and pre‑stored waveform – no external parts, no calibration, 0–40°C guaranteed. For ESL, IoT dashboards, or wearables, this display isn’t a component – it’s your silent competitive edge.
