Description

This 3.7-inch electronic paper screen has a resolution of 240*416 and a classic black and white dual-color presentation, bringing a reading experience like paper. It has high contrast and high reflectivity, as well as the blessing of hard-coated anti-glare technology, ensuring excellent visual performance under various lighting conditions. The ultra-wide viewing angle design allows you to enjoy the same wonderful picture from any angle.

The ultra-low power consumption feature means that this display module can still maintain the picture content without backlight, and will not lose the display information even if the power is off, and only consumes power when refreshing.

Using advanced active matrix electrophoretic display technology, this electronic paper display works in pure reflection mode, providing a comfortable experience close to paper reading. It is not only suitable for application scenarios such as shelf labels, price tags, badges, smart labels and smart homes but also an ideal choice for e-readers, smart wearable devices and other portable devices.

3.7 inch E-Paper screen with SPI interface

Feature

3.7-inch electronic paper screen, 240*416 resolution, black and white, using SPI interface communication;
Even if the power is off, the content is still clearly visible, no need to worry about information loss;
Hard-coated anti-glare display surface, afraid of direct sunlight, outdoor reading is also clear and comfortable;
High contrast and high reflectivity, can provide more excellent visual performance;
Ultra-low current deep sleep mode, basically only needs to refresh the power supply, greatly reduce power consumption, and achieve ultra-long battery life;
Full-viewing angle display, clear and visible at any angle;
