InkPoster: a digital poster that only needs to be charged once a year
What a beast
E Ink, in collaboration with PocketBook and Sharp, has introduced InkPoster, a digital poster based on E Ink Spectra 6 technology that consumes power only when changing images. Thanks to this, the device can work for up to a year on a single charge.
Here's What We Know
InkPoster is available in three sizes:
- 13.3 inches with a resolution of 1200x1600 pixels and a 14,000 mAh battery for $599.
- 28.5-inch with a resolution of 2160x3060 pixels, combining E Ink Spectra 6 and Sharp IGZO technologies for $2,400.
- 31.5-inch with a resolution of 2560x1440 pixels and a 20,000 mAh battery for $1,700.
The device supports Wi-Fi and Bluetooth, which allows you to regularly update images and artwork from the gallery of the proprietary app, or use your own photos. InkPoster emits no light, making it safe for the eyes and environmentally friendly.
Digital photo frames have not become popular due to the need to constantly recharge them and the light that can be disturbing at night. E-ink digital ink technology uses energy only when the image changes, and can exist with zero charge the rest of the time. Typically, e-ink is widely used in e-books, but advances in colour e-ink technology are opening up new ways to use the technology. The Spectra 6 display builds full-colour images by combining ink particles of 6 different colours. The manufacturer does not say how many colours Spectra 6 can reproduce, but the technology is potentially capable of reproducing 60,000 shades, which is enough to reproduce more or less smooth transitions. This value almost corresponds to 16-bit colour. For your understanding: most modern LCDs display an 18-bit image (262,144 colours), and 32-bit colour in computers is a marketing trick, in fact, the colour is 24-bit, an additional 8-bit channel can be used for the transparency effect (the so-called alpha channel), which does not affect the perception of the number of final colours.
