To clear up any confusion, BGR translated both videos' descriptions, albeit using Google Translate. According to the first video, Samsung has developed “Vision Aid Technology,” which is probably just a fancy way to parrot its AMOLED screen:
“Samsung Display AMOLED has developed Vision Aid technology, which allows users experiencing color fading to feel more natural colors. This technology, which can be implemented thanks to the AMOLED’s self-emission method, is a special advantage of display AMOLED for people.”
The second video’s description explains that the phone is thinly built and consumes minimal power, “thanks to its self-luminous structure,” whatever that means.
Whatever phone it is we’re looking at here -- it might not be the S8, after all -- it’s clear that Samsung greatly needs a consumer hit. The exploding battery nightmare that characterized the short-lived Galaxy Note 7 device cost the company $18 billion. If there’s anything to amend the broken bond with its customers, Samsung needs the Galaxy S8 to not explode in people’s pants, and it looks like it might be on the right track.
