Chinese company GeChic has devised the On-Lap 1302 that it is promoting as a second screen for a range of devices including gaming consoles, notebooks, digital cameras and even smartphones. The device requires a slightly complicated set up, however, and cannot connect directly to an external device without an adapter or power supply. In the case of a notebook, power can be supplied over powered-USB, however the setup requires an external battery for a camera or smartphone.
