core advantage

  1. Ultra-Compact Size

    • 1.5-inch diagonal (1.54" typical active area), ideal for space-constrained designs.

  2. High Pixel Density

    • 152×152 resolution (~172 PPI), sharp text/graphics for small displays.

  3. Zero-Power Image Retention

    • Bistable e-ink technology: 0 power consumption when static.

  4. Sunlight Readable & Eye-Friendly

    • Reflective display: glare-free, paper-like visibility in direct sunlight.

  5. Wide Viewing Angle

    • Near 180° viewing with minimal color shift.

  6. Lightweight & Thin

    • Minimalist design for portable/wearable integration.

  7. High Contrast B&W

    • Crisp monochrome output for clear information display.

  8. Memory-in-Pixel Support

    • Built-in memory reduces MCU workload (depends on driver IC).


Target Application Scenarios

  1. Wearable Tech

    • Smart bands, minimalist watches, fitness trackers (time, steps, notifications).

  2. IoT Sensors & Tags

    • Wireless price tags, inventory trackers, smart labels.

  3. Portable Medical Devices

    • Glucose monitors, pill reminders, wearable health sensors.

  4. Industrial Tools

    • Compact meters, calibration displays, handheld diagnostic tools.

  5. Smart Home Devices

    • Thermostat panels, security keypads, appliance status screens.

  6. Electronic Accessories

    • Bluetooth tracker tags (e.g., Tile-style), minimalist smart badges.

  7. Battery-Powered Indicators

    • Long-life status displays for remote sensors or environmental monitors.

  8. Educational/DIY Kits

    • Low-power projects for students/makers (Arduino/Raspberry Pi).

Key Precautions

  1. Refresh Limitations

    • Avoid excessive partial updates to prevent ghosting; periodic full refreshes are mandatory.

    • Full refresh cycle time: ~2 seconds (typical); partial refresh: ~0.3–0.5 seconds.

  2. Temperature Sensitivity

    • Operating Range: -20°C to +70°C. Performance degrades outside this range.

    • Storage Range: -30°C to +80°C. Avoid condensation during temperature shifts.

  3. Voltage Requirements

    • Strictly adhere to specified logic voltage (e.g., 3.3V/1.8V) and driver voltage (e.g., VCOM ~±15V). Overvoltage damages controller IC.

  4. ESD Protection

    • Handle with anti-static precautions. ESD can permanently damage e-ink film.

  5. Mechanical Stress

    • Do not bend, press, or puncture the screen. The glass substrate is fragile.

    • Avoid direct contact with the e-ink layer (no cleaning agents or sharp objects).

  6. UV Exposure

    • Prolonged direct sunlight may accelerate e-ink film degradation. Use UV-filtering covers in outdoor deployments.

  7. Power Sequencing

    • Follow power-on/off sequences in the datasheet to avoid latch-up or image corruption.

FAQs

Q1: Why is the screen slow to update?
A: E-paper relies on physical particle movement. Full refresh takes ~2s for clean transitions; partial refresh is faster (~0.3s) but may require full refreshes periodically to eliminate ghosting.


Q2: Can I use it with Arduino/Raspberry Pi?
A: Yes, but you’ll need a compatible driver board (e.g., SPI interface). Libraries like GxEPD2 (Arduino) or waveshare-epd (RPi) simplify integration.


Q3: Why does the display show ghosting?
A: Caused by incomplete particle realignment. Fix: Trigger a full refresh cycle every 5–10 partial updates. Avoid high-contrast image switches without full refreshes.


Q4: Does it really consume zero power?
A: Yes, when displaying a static image. Power is only consumed during screen refreshes. The controller IC may have minimal sleep current (~5–10µA).


Q5: Can I cut or resize the display?
A: No. The glass substrate and e-ink film are factory-sealed. Physical modification destroys the display.


Q6: Why is my display blank after power-up?
A: Check:

  • Voltage levels (logic/VCOM)

  • SPI communication signals

  • Reset sequence timing

  • MCU code initialization routine

Q7: How do I handle image persistence in cold/hot environments?
A: Below 0°C, refresh time increases significantly. Above 50°C, particles move faster but may cause flickering. Use temperature compensation algorithms if supported by the driver IC.


Q8: Is touch functionality supported?
A: No, this is a display-only module. Touch requires an external overlay (not recommended due to added thickness/reflectivity).


Q9: Can I drive it without a controller board?

A: Not recommended. You need a dedicated driver IC (e.g., SSD1681) to generate high-voltage waveforms for e-ink particle movement.


Q10: What causes "burn-in" effects?
A: Unlike OLED, e-paper has no permanent burn-in. However, extreme long-term static images (months/years) may cause temporary retention. Fix: Cycle through full-black/white screens.
