E-Ink is showing off a number of products at SID Display week and one of the most interesting is four different Pearl screens that are showing different segments of the an image of a Zebra. Each of the screens have a resolution of 2880×2160 and 85 PPI. Each panel has a 3:4 accept ratio, the display is capable to display images at 2-16 gray levels (1-4 bits) depending on the display controller and the associated waveform file it used.
Each of these screens are fairly expensive on their own. E Ink is selling them on their online shop for $2,500 each, so this installation would set you back $10,000.
These screens are not really out in the wild, due the high cost. Many of the companies that do digital signage are using 32 inch screens or smaller. This includes Papercast, Visionet and other people who sell the signs and the API to control the images. The only 42 inch screen that is being used is the Quilla whiteboard.
