Ultra-Low Power E-Paper with Integrated Frontlight for Industrial IoT

The SFE213QXBW-7353A-FL is a 2.13" E-ink display module featuring built-in frontlight and 0.3-second partial refresh – engineered for battery-operated devices requiring sunlight readability and instant content updates. Ideal for Electronic Shelf Labels (ESL), portable medical devices, and smart sensors, it combines bistable technology (zero power to retain images) with SPI-programmable waveform optimization for extreme energy efficiency.

Key Differentiators for Harsh Environments

(1) Integrated Frontlight & Rapid Refresh

• Edge-lit LED frontlight ensures uniform backlighting in low-light conditions (e.g., warehouses, night shifts).

• 0.3-second partial refresh (vs. 1.8s full update) minimizes UI latency during dynamic data changes (price updates, sensor readings), reducing power consumption by 70% (Page 8).

(2) Engineer-Optimized SPI Control

• Dual-mode SPI (3-wire/4-wire selectable via BS1 pin) compatible with low-power MCUs (ESP32, nRF52).

• Temperature-aware waveform LUT (Command 0x32) and VCOM OTP programming (Command 0x2A) eliminate screen flicker across operating temps (-25°C to +70°C storage).

(3) Custom CTP Integration for Interactive Applications

• Expandable capacitive touch (CTP) via dedicated I²C pins (TSCL/TSDA) with glove/touch support.

• Hardened surface: Anti-glare coating (≥6H hardness) resists scratches in high-traffic retail/industrial settings.

Technical Specifications for System Integration

• Ultra-Low Power Architecture: 10.5 mW active power, 1–5 µA deep sleep (Command 0x10) for decade-long battery life.

• Optical Excellence: 35% reflectivity (CIE 1931 standard), 180° viewing angle, and 8:1 contrast under 45° illumination (Page 23).

• Robust Reliability: Validated for 240 hrs at 90% RH humidity, ±8kV ESD, and UV resistance (Page 24).

• Slim Profile: 1.65 mm thickness with FPC stiffener for vibration-prone deployments.

Compliance & Customization

◾ EU/US Certified: RoHS 3 (EU 2015/863), REACH SVHC, and EU 2025/40 recyclable packaging.
◾ CTP Customization: OCA lamination, anti-fingerprint coating, extended temperature (-30°C~85°C).

Target Applications

• Retail: ESLs, digital price tags

• Healthcare: Medication trackers, portable diagnostics

• Industrial: IoT sensors, warehouse logistics trackers

• Smart City: Parking meters, environmental monitors
