The Wemax Go is a DLP projector rated to throw an up to 120-inch image with HDR support and a maximal brightness of 600 ANSI lumens. However, unlike most products with such specs, it is also designed to be just 1 inch in height. Its maker, asserting that it is the thinnest product capable of the ALPD standard, has put it up for crowdfunding on Indiegogo.
