3.5" ePaper Display 240×360 - SPI
This 3.5-inch Active Matrix Electrophoretic Display (AM EPD) delivers a crisp 240×360 pixel resolution with pure reflective technology, ensuring optimal visibility in various lighting conditions. Designed for energy-efficient operation, it features bi-stable display capabilities that maintain images without continuous power draw—ideal for battery-powered devices like Electronic Shelf Label (ESL) systems. The module integrates a full suite of components including on-chip RAM, DC-DC converters, and temperature sensor interfaces, supporting both 4-wire and 3-wire SPI communication for flexible integration.
With an active area of 49.67mm × 74.505mm and pixel pitch of 206.9μm, the display offers sharp, legible text and graphics. The ultra-wide viewing angle and high reflectance mimic paper-like readability, while the deep sleep mode reduces power to just 1μA—extending battery life in portable applications.
- Dual SPI Interface: Supports 4-wire SPI (with D/C control) and 3-wire SPI (9-bit protocol) for compatibility with various microcontrollers.
- Integrated Power Management: On-chip booster and regulator generate driving voltages (VCOM, VGH, VGL), minimizing external components.
- Temperature Compensation: Built-in I2C interface for external temperature sensors, ensuring stable performance across environments.
- Robust Construction: Weighing only 8.2g with a slim 0.82mm profile, designed for durability in commercial deployments.

The display supports two SPI modes selectable via the BS pin: 4-wire SPI (using SCLK, SDIN, CSB, and D/C pins) for standard command/data separation, and 3-wire SPI (9-bit format with embedded D/C bit) for reduced pin count. Both modes operate at clock cycles up to 4MHz with precise timing constraints.
- 4-wire SPI: D/C pin controls data (high) vs. command (low) transmission on rising clock edges.
- 3-wire SPI: First bit in 9-bit sequence acts as D/C flag, followed by 8 data bits.
Timing parameters include minimum clock cycle of 250ns, data setup time of 50ns, and hold time of 15ns to ensure reliable communication.
We offer tailored solutions for bulk deployments and custom integrations, including white-label options and volume pricing for large-scale ESL systems or IoT devices.
- Custom Configuration: Modify interface parameters, firmware, or mechanical housings to match specific application needs.
- Bulk Order Programs: Discounted pricing for orders exceeding 100 units, with dedicated technical support.
- OEM/ODM Services: Full customization of display parameters, branding, and packaging for integrators.
Ideal for retail ESL systems due to ultra-low power consumption, bi-stable image retention, and high visibility under indoor lighting. Supports rapid price updates via SPI.
Used in handheld devices like digital notepads or sensors where sunlight-readable, low-energy displays are critical. Partial refresh enables smooth updates without flickering.
Deployed in warehouses or factories for asset tracking, with durability to withstand temperature variations (0°C–35°C) and mechanical stress.
Implementation Notes: Ensure proper decoupling capacitors (e.g., 1μF X5R/X7R rated 25V) are placed near power pins. Avoid exposure to temperatures outside 0°C–35°C during operation to prevent damage. Use the BUSY pin to monitor display readiness before sending new commands.
