Principle of Electronic Paper
The electronic ink screen is an electronic paper device that adopts the MED image display technology of the microencapsulated electrophoretic display. The original method is to create tiny spheres in which charged pigments are suspended in transparent oil and will move according to the electrical charge. The electronic paper screen displays patterns by reflecting ambient light, so it has no background light requirements. In the sun, the electronic paper screen still has a wide viewing angle of 180 degrees and high visibility. This is ideal for e-reading. After the screen is powered off, the last screen can still be retained for a long time, which can be as long as half a year. Therefore, it has also been widely used in the field of electronic labels for display applications such as shelf labels and industrial instruments.
Introduction
-The screen size of this module is 1.54 inches, the resolution is 200×200, it has an internal controller, uses SPI interface to communicate, and supports partial refresh.
-Low power consumption, wide viewing angle, and clear display even after power off. It is used for display applications such as shelf labels and industrial instruments.
Features
1. There is no need for backlight, the last screen display content can be kept for a long time after power off, the time can be up to half a year
2. Very low power consumption, basically only consumes power when refreshing
3. SPI control interface, which can be connected to main control boards such as Raspberry/Arduino/STM3
4. Provide complete supporting information (Arduino sample program, showing global display and partial display)
