Over the years, we've seen multiple attempts at launching notebooks with dual displays, i.e. one on the outside and one on the inside of the lid. None have been particularly successful and there has never been a followup model from the manufacturers that have launched said products. At Touch Taiwan, InnoLux had a demo of a new take on the dual display laptop, where the company had managed to make both display panels a mere 4.5 mm thick. On top of the relative thinness of the two panels, both panels also featured touch and stylus support, although it might have been enough if the outer display had this, so a potential notebook could be used in tablet mode this way and like a regular notebook when flipped open.

InnoLux didn't specify the display pane size, but both panels have a 3:2 aspect ratio and a rather odd 1526 x 1024 resolution, with a contrast ratio of 1200:1. It appears that the displays are intended for the educational market for the time being, most likely for some overpriced Chromebooks that are being pitched to schools. That said, this is the best concept of a dual display laptop screen we've seen, as the thickness equals that of most regular laptop displays, so there's no extra bulk for additional display.
