DASUNG introduces the world’s first color E-ink monitor (Crowdfunding)

Just a couple of years ago, we would have laughed at the idea of getting an E-ink monitor, because most displays were still in black and white only, larger displays were prohibitively expensive, and nobody wanted to wait for several seconds to get a full display refresh. But there’s been some good progress in recent years with color displays, faster refresh rate, and prices coming down somewhat which has led to the launch of devices such as the Onyx BOOX Tab Ultra C 10.3-inch color E-Ink Android tablet and a range of color eReaders such as the PocketBook Color. But DASUNG is going further with the launch of the world’s first color E-ink monitor. DASUNG E-Ink color monitor specifications: 23.5-inch color E-ink Kaleido 3 color screen with 3200 x 1800 resolution 4096 colors through DASUNG X-Color Filter “Ultra-fast Turbo Refresh Tech” Optional frontlight and/or curved display (depends on model) Landscape […]

Inkplate 5 – A 5.2-inch wireless e-paper display programmable with Arduino or MicroPython (Crowdfunding)

The team at Soldered Electronics has been designing Inkplate ESP32-based e-paper displays ever since the first 6-inch model was launched in 2019. The latest Inkplate 5 comes with a recycled 5.2-inch E-Ink (e-paper) display with refresh times of only 0.19 seconds, and programmable with the Arduino IDE or MicroPython firmware. The WiFi-connected display offers a 960×540 resolution, or 213 DPI pixel density, integrates an RTC with battery for accurate timekeeping, two buttons for power and wake/user, and I/O expansion via headers and an easyC/Qwicc connector. Inkplate 5 specifications: Wireless module – Dual-core ESP32 processor with Wi-Fi 4 & Bluetooth 4.0 (BLE) connectivity, 8MB flash, 4MB PSRAM External storage – MicroSD card socket Display – 5.2-inch, 960×540 e-paper display with 213 DPI pixel density Refresh times: full refresh in just 1.02s (1-bit and 3-bit) and partial refresh in 0.19s (1-bit) USB – 1x USB Type-C port for programming and power Expansion […]

Badger 2040 W e-Paper display gets WiFi & Bluetooth with Raspberry Pi Pico W

Pimoroni Badger 2040 W wireless programmable e-Paper badge comes with a 2.9-inch black & white E-Ink display and a Raspberry Pi Pico W board for WiFi (and Bluetooth) connectivity. It is an update to the Pimoroni Badger 2040 with the exact same display, but instead of using a Raspberry Pi RP2040 microcontroller, Pimoroni fitted a Raspberry Pi Pico W on the back of the board, probably to avoid going through FCC and CE certifications. Badger 2040 W specifications: MCU board – Raspberry Pi Pico W board with: Raspberry Pi RP2040 dual-core Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM Storage – 2MB QSPI flash Wireless – 802.11b/g/n WiFi 4 and Bluetooth Classic+LE with ABRACON onboard antenna (Infineon CYW43439 connected over SPI) Display – 2.9-inch B&W E-Ink display with 296 x 128 pixels resolution, ultrawide viewing angles, ultra-low power consumption; Dot pitch – 0.227 x 0.226 mm […]

$150 InkPalm Plus eReader features RK3566 SoC, 5.84-inch display

Xiaomi Moaan InkPalm Plus is a 5.84-inch eReader powered by the same Rockchip RK3566 processor found in Pine64 PineNote 10.3-inch Linux eReader, and currently selling for 999 CNY, or about $150 US, on JD.com after a 100 CNY discount. The device looks more like a smartphone than an eReader with its relatively small display, but there must be demand for this type of hardware since it succeeds the earlier InkPlam 5 eReader with Allwinner B300 quad-core Cortex-A7 SoC, plus an even smaller 5.2-inch display. Inkpalm Plus specifications: SoC – Rockchip RK3566 quad-core A55 processor @ 1.8 GHz with Arm Mali-G52 EE GPU, 0.8 TOPS NPU (AI accelerator) System Memory – 2GB RAM Storage – 64GB eMMC flash Display – 5.84-inch E Ink display with 1440×720 resolution (276 PPI), front light with 24 levels and adjustable color adjustment, 5-point capacitive touch Audio – Mono microphone Connectivity – Dual-band 802.11b/g/n/ac WiFi 5, […]

E Ink Gallery 3 color ePaper offers faster refresh rate, higher resolution

This is confusing. E Ink just announced the Kaleido 3 color e-paper at the beginning of the month, and now comes up with E Ink Gallery 3 color e-paper. Before we try to look into the differences, let’s see what E Ink says about the new Gallery 3 color ePaper technology. Designed for the eReader and eNote markets, E Ink Gallery 3 is based on the E Ink ACeP (Advanced Color ePaper) with a full-color gamut achieved through a four-particle ink system: cyan, magenta, yellow and white, which allows a full-color gamut at each pixel. The earlier E Ink Gallery has a black and white update time of two seconds, and color updates of ten seconds. The new Gallery 3 ePaper technology slashes those times to 350ms for black and white and as low as 500 ms in fast color mode. The standard and best color modes have refresh rates […]

E Ink Kaleido 3 color e-paper display increases color saturation by 30 percent, reduces blue light reflections

E Ink’s latest Kaleido 3 color ePaper display increases color saturation by 30 percent compared to the earlier Kaleido Plus color e-paper display, integrates E Ink ComfortGaze new front light technology engineered to reduce the amount of blue light reflected off the surface of the display, in order to provide further comfort while reading. The new modules based on Kaleido 3 will be offered in various panel sizes including 7.8-inch, 10.3-inch, and 13.3-inch, support up to 16 levels of grayscale and 4096 colors, and target eReaders and eNote devices. E Ink explains that Kaleido 3 relies on the company’s Print Color ePaper technology, “where a color filter array (CFA) is used in conjunction with E Ink’s Carta black and white ink film, creating a full-color device for a more fully realized eBook shopping and reading experience”. As I understand it that part has not changed, and it’s just the same […]
