High-Definition Display

The 4-inch Electrophoretic Display boasts an impressive 4.0-inch display with a resolution of 528×768 pixels. It offers color display in black, white, red, and yellow, facilitating vibrant and diverse visual outputs. Featuring high contrast, the 4-inch e-ink display modules ensure brilliant and vivid image clarity. It boasts different refreshing displays for stunning details. Better yet, our e-paper modules highlight the ultra-wide viewing angle, allowing for superior readability from various perspectives.

Energy-Efficient Operation

The 4-inch EPD module operates in a pure reflective mode, utilizing natural light to enhance display visibility and minimize power usage. Based on bi-stable display technology, no further energy is required once the ePaper module’s image is shown. Moreover, the 4-inch electrophoretic display features an ultra-low current deep sleep mode and conserves more energy when the device is inactive. It’s durable and user-friendly in different conditions.

High-quality Components

Each e-paper display module is designed for efficiency, integrating essential components such as gate and source buffers, interface circuits, and timing control logic. These components are crucial for the smooth operation and responsiveness of the display: The on-chip SRAM and a look-up table (LUT) ensure quick data access and effective color management. An integrated oscillator and DC-DC converter maintain stable performance under varying power conditions, while internal VCOM and border management systems guarantee uniform image quality. The 4-inch e-ink display module boasts robust connectivity options, including a serial peripheral interface and an I2C master interface for comprehensive sensor communication. Thus the 4-inch e-paper module can monitor built-in and external temperature sensors, adapting to different thermal environments.

4 Inch E-Ink Display Module Care & Warnings

1. Adhere to all guidelines to ensure 4-inch e-ink display module’s longevity and optimal performance.
2. Keep the display flat or mounted on a rigid, curved support. Avoid continual bending along the long axis.
3. Do not touch leaking materials if the display breaks. If contact occurs, wash the area immediately with water and soap.
4. Protect the 4-inch e-paper module from corrosive gases like acids and alkalis. Avoid exposure to static electricity and harsh conditions.
5. Apply IPA solvent only to the active area and back of the glass. Do not disassemble the 4-inch e-ink modules to prevent damage and void the warranty.
6. Handle the fragile glass carefully, especially the front surfaces. Follow standard practices for handling delicate electronics.
