Elecrow 5.79-Inch Low-Power E-paper Display Review

This CrowPanel ESP32 5.79” electronic paper HMI Display (E-Paper) is an advanced display technology. It uses an active matrix electrophoretic display and a hard-coated anti-glare display surface to keep the content visible even in sunlight, perfectly mimicking the appearance and reading experience of traditional paper. It boasts a high resolution of 272*792, offering a vivid display effect, and features the classic black and white display, suitable for various application scenarios.

We have previously reviewed the RCO50S 5-Inch HD Capacitive Touchscreen Monitor and the CrowPanel Advance 7.0-HMI ESP32 AI Display, both of which are excellent display products designed for industrial, home, medical, and agricultural applications. However, in this post, we’re not discussing those displays; instead, we will focus on the new 5.79-inch E-paper Display from Elecrow. And if you’re thinking, “Not another E-paper display,” think again—this one stands out from the rest.

The Elecrow 5.79-inch E-paper Display is a low-power, black-and-white electronic paper screen with a 272×792 resolution and SPI interface. Like other e-paper displays, this one also retains displayed content without power and offers excellent readability in sunlight. So, what’s different about this one?

The difference is in its partial refresh feature, meaning you can update only a section of the screen, which is huge, and many other displays will not have this feature. Not only that, it also supports full viewing angles, ultra-low deep sleep current, and can run from a single-cell lithium battery as it has a perfect operating voltage range of 2.2V–3.7V. The display uses the SSD1683 driver, meaning it’s also compatible with most of the MCUs and features a hard-coated anti-glare surface. This form factor and compact size make this device suitable for embedded or handheld devices.

Design and Build Quality

Right out of the box, the 5.79-inch e-paper panel feels good and features great display quality altogether. It’s large, it has 272×792 resolution, which makes it easy to display multi-line content while being slim and light (just 60g), making it ideal for compact enclosures or embedded designs. As mentioned earlier, it’s protected with an anti-glare layer, which makes reading under direct sunlight easy. Another interesting thing about this display is that the mechanical dimensions of the display are well-documented, so if you are planning to make an enclosure for the display, Elcrow has got you covered. Additionally, it features a 24-pin 0.5mm connector that you can use to connect the display to a suitable MCU. In theory, everything looks good, but the company does not provide any breakout boards for the display, so beginners might find it tricky without prior experience in handling flat ribbon cables or designing a carrier PCB.

Display Performance

The form factor makes the display very well suited for various applications. The display is rectangular, icons look clearer, and the text is easy to read, especially for list-style content, vertical tags, or barcodes in the supermarket. It has a great contrast ratio, which makes it readable in both indoor lighting and direct sunlight. Like most E-paper displays, it uses no power to hold an image, so even if you unplug it, the screen stays as it is, making it ideal for low-power or battery-based projects.

Compatibility

The display features two SSD1683 driver ICs and uses the SPI communication protocol for communicating with the MCU. It has clearly labeled pins SCL, SDA, CS, DC, RES, and BUSY, making it easy to connect with most SPI-based e-paper libraries, and we all know that the SSD1683 driver ICs have a lot of libraries and community support. The operating voltage of this device is between 2.2V to 3.7V, making it perfect for a battery-operated device. You can also use this display with 3.3V logic microcontrollers like the ESP32, STM32, or Raspberry Pi Pico. But one thing you need to remember is that there’s no built-in voltage regulator or level shifter on the display, so you need to be careful and make sure you don’t connect it directly to 5V microcontrollers without using a level converter.

Power Efficiency

This is where an e-paper display outnumbers everyone. It features an ultra-low power deep sleep mode where the current draw is almost negligible, allowing your project to run for weeks or even months on a single charge. Since the display retains static content like time, labels, or sensor data without needing constant refresh or power, it’s a perfect fit for off-grid displays, solar-powered devices, or remote sensors where updates are less frequent.

Technical Drawbacks

One downside of this display is that no breakout or dev board comes with the display, so you need to make a custom PCB or use an FFC breakout board for connecting and testing the display. Also, there are no official Arduino examples, while third-party SSD1683 libraries work; a basic setup guide from Elecrow would help. Lastly, the display only supports black and white, with no red or yellow options like some other e-paper screens.
