New color e-paper monitors – 13.3-inch DASUNG Paperlike 13K and 23.5-inch BOOX Mira Pro Color

DASUNG Paperlike 13K ports epaper color monitor

Back in 2023, DASUNG launched its first color E-Ink monitor, quickly followed by BIGME B251 computer and standalone E-Ink monitor. Both were based on the same 23.5-inch E-ink Kaleido 3 color display with 3200×1800 resolution, and were rather pricey at $1,529 (Indiegogo price) and $1,299 (Kickstarter price), respectively. Let’s revisit color e-paper monitors in 2025 with two new models that were just announced: the DASUNG Paperlike 13K 13.3-inch e-ink color monitor and BOOX Mira Pro (Color version) with the same 23.5-inch E-Ink Kaleido as competing monitors launched in 2023. Those monitors are particularly well-suited for people spending long hours in front of the screen, and don’t need to watch video and play games due to the lower refresh and ghosting effect. It’s supposed to be friendlier to eyes, and there’s no blue light.

Samsung 32″ EMDX color e-paper display runs Tizen 8.0, offers 2560×1440 resolution, up to 200 days of battery life

Samsung 32" EM32DX color E-paper Display

Samsung has unveiled a 32-inch color e-paper display with WQHD (2,560 x 1,440) resolution and a built-in 4,600mAh battery that can last up to 200 days on a charge if the display is updated once a day. The Samsung 32″ EMDX color e-paper display is mainly designed for digital signage applications in shops, restaurants, public transportation, and public spaces. Like other e-paper displays, it does not consume any power if the image is unchanged. I was initially surprised at the bright colors of the EMDX display from the photos shared by Samsung, but after a closer look, I’m not convinced those are photos of the actual display.

LILYGO T-Deck Pro – An ESP32-S3 LoRa messenger with e-paper touch display, keyboard, and 4G LTE or audio codec option

LILYGO T-Deck Pro is a LoRa messenger based on an ESP32-S3 WiFi 4 and Bluetooth 5.x SoC, and offered with a 3.1-inch e-paper display with touchscreen, a Blackberry-like QWERTY keyboard, a GPS module, speaker, microphone, and a 3.5mm audio, as well as IMU and light sensors. It builds upon the T-Deck Plus design, but replacing the 2.8-inch IPS display with a 3.1-inch e-paper display allows for a slimmer design and should offer longer battery life despite the smaller 1,400 mAh battery used in the new model. Two versions of the T-Deck Pro are available: one with a Simcom 4G LTE modem and a cheaper one with a PCM5102A audio codec. LILYGO T-Deck Pro specifications: SoC – ESP32-S3FN16R8 CPU – Dual-core Tensilica LX7 microcontroller @ up to 240 MHz 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash Storage – MicroSD card […]

Batteryless 7.5-inch NFC-powered e-paper display V2 gets new NFC chip and “fast flashing method”

7.5inch NFC Powered e Paper V2 side view

Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock.
