4.2" ePaper Display 400×300 - SPI I2C
This 4.2-inch Active Matrix Electrophoretic Display (AM EPD) delivers a high-resolution 400×300 pixel array in a pure reflective, bi-stable format ideal for low-power portable devices. The module integrates gate/source buffers, MCU interface, timing control, DC-DC converter, SRAM, LUT, and VCOM circuitry, supporting SPI interfaces and I²C communication for external temperature sensing.
Engineered for clarity and efficiency, the display offers ultra-wide viewing angles and consumes just 3 µW in deep sleep mode. Its commercial temperature range (0°C to 50°C) ensures reliability in varied environments.
- Ultra-Low Power Design: Deep sleep mode reduces power to 1 µA, while typical operation draws 15 mA at 3.0V.
- Integrated Control Logic: On-chip oscillator, booster, and regulator generate driving voltages (VCOM, Gate, Source) without external components.
- Dual SPI Modes: Supports 4-wire and 3-wire SPI interfaces, selectable via the BS pin for flexible MCU integration.
- Temperature Compensation: I²C master interface reads external digital temperature sensors for optimized performance.

We offer customized bulk solutions for large-scale deployments, including tailored configurations and white-label options for integrators.
- Volume Discounts: Competitive pricing for orders exceeding 100 units, with flexible payment terms.
- Custom Firmware: Adaptation of drive waveforms and LUTs for specific application requirements.
- Technical Support: Dedicated engineering assistance for integration and troubleshooting.
Ideal for retail pricing systems due to bi-stability (no power needed to maintain display) and high visibility under indoor lighting.
Used in handheld diagnostic tools where low power and sunlight-readable screens are critical.
Deployed in sensor readouts and control panels requiring wide temperature tolerance and long battery life.
The display supports multiple MCU interfaces with minimal external components. Interface mode is selected by the BS pin:
- 4-Wire SPI: Uses separate D/C pin for command/data distinction; clock speeds up to 4 MHz.
- 3-Wire SPI: Embeds D/C bit in a 9-bit packet; compatible with resource-constrained controllers.
