Modos Paper Monitor Brings High-Speed E-Paper to Developers

Modos Tech has announced the Modos Paper Monitor, a 13.3‑inch open‑hardware e‑ink display designed for real‑time use. Unlike traditional e‑paper, it supports refresh rates of 60 to 75 Hz with sub‑100 ms latency, enabling smooth interaction and multiple image modes.

The Modos Paper Monitor is powered by the Caster e‑paper controller, which is built on a Xilinx Spartan‑6 LX16 FPGA with DDR3‑800 framebuffer memory. The hardware supports electrophoretic panels from manufacturers such as E Ink and SiPix. With a processing rate of up to 200 MP/s, it enables multiple grayscale modes including binary, 4‑level, and 16‑level, with optional dithering algorithms such as blue‑noise and error‑diffusion.

Latency is kept below 20 µs, and the board supports regional refresh for reduced ghosting and improved responsiveness.
