2.7 INCH E-INK DISPLAY
Display some stuff on E-Ink display is a series of chemical changes. For E-Ink display, power only needed during refresh time, pictures can keep shown in the display without any power for more than 180 days. The content displayed is the same as written on paper. Very suitable for shelf labeling, ID tag.
2.7 inch E-ink Screen is a part of the “E-INK Display“ series, with the following features:
- Adopt to IL91874 driver chip;
- Digital supply voltage: 2.3~3.6V;
- Display Resolution: 264 x 176;
- Power consumption only when refreshing, power consumption: 26.4mW, content can keep shown in the display without any power more than half a year;
- Provide Arduino and STM32 (Keil) example code;
