Ultra-thin OLED TVs, Sony Bravia A1 4K OLED TV

Sony unveiled its first Bravia 4K OLED TV, dubbed the A1E series in the US and A1 in the UK, at CES 2017. The TV will come in 55-, 65- and 77-inch versions What makes this OLED TV stand out from the crowd is Sony’s Acoustic Surface technology, which makes sound by vibrating the screen. That means the sound comes directly from the screen, removing the need for extra, visible speakers. The Sony A1E (or A1) will also support the Dolby Vision variant of HDR. Previously, LG was the only major brand to offer Dolby Vision alongside the more common HDR10 format.
