2.1″ Low Temp Display

Overview

The 2.1″ Lectum Low Temperature display is a flexible active-matrix EPD with Ultrachip UC8156 single chip EPD controller, integrated drivers and power management. It supports 240 x 146 pixels and operates as low as -25°C .

This display is particularly suitable for smart cards, wearables and labels where operating at a lower temperature is a requiment.

It is available as engineering samples and in volume, and can be ordered on request.
