While it seems more and more these days, the emphasis is on the smaller screens and ones of all sorts of sizes, it looks like research at Google’s X lab is working on creating screens that are able to connect to each other without having obvious seams and unsightly bezels. These devices will also be complete with the software that enables the connected screens to adjust with ease to create one larger screen, no matter what screen sizes the different components might have.
The possibilities, of course, are pretty endless. You can build any size screen to your liking, from making a screen out of four phones connected side-by-side for a game like in the demonstration below or building a massive behemoth of a screen for, say, the Superbowl.
