Inland 2.13 Inch E-Ink Display Screen
High-contrast electrophoretic active-matrix display module engineered for low-power embedded edge nodes, electronic shelf labels (ESL), smart metering, and micro-power IoT instrumentation.
Engineered for Ultra-Low Energy & High-Sunlight Readability
Unlike active liquid crystal or emissive displays, electrophoretic micro-capsules maintain contrast indefinitely without persistent electrical stimulus.
Bistable Zero-Power Retention
Once written, micro-particles stay locked in place. Power is strictly required during pixel state transition cycles, enabling 5+ year runtime on coin-cells.
Paper-Grade Sunlight Contrast
Pure ambient light reflection replaces power-hungry LED backlights. Direct sunlight actually increases contrast ratio without washout or thermal degradation.
>170° Omnidirectional View
True Lambertian reflectance delivers unrestricted viewing angles with zero color inversion, contrast drop, or polariser distortions seen on TFT screens.
Standard SPI Micro-Bus
Drop-in hardware compatibility with embedded C drivers, Arduino GxEPD2, Adafruit GFX, U8g2, and STM32 HAL libraries for rapid rapid OEM prototyping.

Parameters verified under standard laboratory ambient conditions: Ta = 25°C, VDD = 3.3V.

Inland 2.13" E-Ink vs. Conventional Industrial LCD
Evaluating trade-offs between bistable electrophoretic technology and liquid crystal modules ensures informed design-in selection for mission-critical hardware.
-
done
Infinite Static Image Retention:
Retains zero-power image retention for months. Energy consumed exclusively during micro-particle migration.
-
done
Superior Ambient Glare Resistance:
High specular reflectance mimicking ink on clean white paper. Readable under 100,000 Lux desert sunlight.
-
done
Micro-Power Battery Profile:
Draws less than 1µA during deep sleep mode. Easily powered for 3-7 years on a single CR2450 coin cell.
-
info
Discrete Refresh Cadence:
Takes 1.5s for full refresh; 0.3s for partial updates. Not suitable for rapid video or motion animations.
-
close
Requires Continuous Drive Voltage:
Immediate image loss upon power cut. Liquid crystals relax instantly without constant AC polarity reversal.
-
close
Sunlight Washout & High Heat:
Direct solar rays overpower standard 300-500 nits backlights, rendering graphics unreadable without high backlight draw.
-
close
Heavy Baseline Current Drain:
LED backlights consistently draw 15-40mA continuously, depleting primary coin cells within days.
-
done
High Dynamic Frame Rates:
Supports 60Hz video playback, fluid waveform oscilloscopes, and real-time interactive touch sliders.
Proven B2B Application Topologies
From industrial smart warehousing to battery-restricted field telemetry, the Inland 2.13" panel excels in demanding deployments.
Battery-Powered Field Sensors
Displays periodic sensor readings, LoRaWAN / NB-IoT network registration status, and localized environmental telemetry with multi-year operation.
Electronic Shelf Labels (ESL)
High-density digital price tags, dynamic barcode/QR code stock trackers, and warehouse bin allocation displays that remain readable under store lighting.
Embedded Instruments
Calibration displays, portable blood analyzer status badges, pharmaceutical cold-chain data loggers, and dosage tracking enclosures.
Grid & Water Flow Gauges
Outdoor gas, water, and electrical utility sub-meters requiring persistent numeric readouts even when main distribution bus power experiences an outage.
Hardware Interface & Pin Definition
Follow these integration rules to achieve stable bus communication with ESP32, STM32, Arduino Uno/Nano, and Raspberry Pi platforms.
Verify Supply & Logic Rail (2.3V - 3.6V)
While our PCB module features integrated level clamp diodes, running native 3.3V logic (e.g. ESP32, STM32) maximizes efficiency. For 5V Arduino Uno boards, ensure proper level matching on DIN and CLK lines.
Standard 4-Wire SPI Hardware Setup
Connect DIN to Host MOSI, CLK to Host SCK, CS to any active-low GPIO, and D/C to command/data selector GPIO. Set SPI Mode 0 (CPOL=0, CPHA=0).
BUSY Pin Interfacing (Critical for Life Expectancy)
Never issue SPI commands while the BUSY output pin is High (indicating internal charge pump booster activity). Wait for BUSY to transition Low before next packet.
Deep Sleep Power Command (0x10)
Always issue software Deep Sleep command after screen refresh completion. This shuts down on-board high-voltage generation circuits, dropping module current below 1µA.
