Product Details: JicTech 4.2‑Inch E‑Paper Display Module

Overview

The JS0420NQ04‑MNG‑A0 is an Active Matrix Electrophoretic Display (AM EPD) module designed for high‑efficiency, low‑power portable applications. With an active area of 4.2 inches and a resolution of 400×300 pixels, it offers excellent readability, wide viewing angles, and bi‑stable operation—meaning it consumes power only during content updates. The module integrates all necessary drivers, DC‑DC converters, SRAM, and timing control, making it easy to interface with common MCUs via SPI.

主な特徴

  • High‑Speed Refresh: Partial update as fast as 400ms, full refresh within 900ms.

  • Ultra‑Low Power: Deep sleep mode down to 1 µA; sleep mode with RAM retention at 35 µA.

  • Integrated Design: On‑chip OTP for waveform storage, built‑in temperature sensor support, and internal voltage regulators.

  • Dual SPI Interface: Supports both 4‑wire and 3‑wire SPI for design flexibility.

  • High Optical Performance: White reflectivity >30%, contrast ratio up to 10:1.

  • Robust Construction: Commercial temperature range, hard‑coated surface, and reliable panel longevity.

  • Easy Integration: Includes busy indicator, reset, and chip‑select pins for seamless MCU communication.

Applications

  • Electronic Shelf Labels (ESL)

  • Portable information displays

  • Smart badges & access cards

  • IoT status indicators

  • Industrial instrumentation
