At some point in the last couple of years it was apparently decided that the bezel is the final aesthetic frontier to be overcome in the quest to make truly great TVs. The Samsung Galaxy S8's infinity display is currently leading the charge on mobile handsets, but LG and Xiaomi have also been waging the fight against TV bezels. At this year’s IFA in Berlin Toshiba decided it was time to show off its own attempt. 

There's still a small bezel of course, but the aim at the moment seems to be to make it as thin and unnoticeable as possible rather than to eradicate it completely. Baby steps.
