(worldkings.org) Sony Xperia 1 was revealed to the public at a press conference held at the annual 2019 Mobile World Congress event On July 02nd, 2022, World Records Union (WorldKings) officially declared Sony Xperia 1 as “World’s first smartphone with a 4K HDR OLED display”.

Based on the world record nomination from Asia Records Institute (ASRI) and Decision No. WK/USA.INDIA/850/2022/No.306, World Records Union (WorldKings) officially recognizes Sony Xperia 1 as World’s first smartphone with an 4K HDR OLED display on July 02nd, 2022.

The Sony Xperia 1 is an Android smartphone manufactured and marketed by Sony. Part of Sony's flagship Xperia series, the device was announced to the public at a press conference held at the annual 2019 Mobile World Congress event on February 25, 2019.

It is the world's first smartphone with an ultrawide 21:9 aspect ratio 4K HDR OLED display, dubbed CinemaWide, and Sony's first triple lens camera system featuring Eye AF eye-tracking technology seen in the company's Alpha line of professional-grade cameras. The Xperia 1 was later joined by a more compact variant, the Xperia 5, which was revealed on 5 September 2019. Compared to the Xperia 1, the Xperia 5 has a smaller 1080p screen, a smaller battery and a non-centrally aligned camera module.

The Sony Xperia 1 consists of a 7000-series aluminum alloy chassis that has a curved edge all around the device, a 2.5D scratch-resistant front and curved-edged back glass panels made of Corning Gorilla Glass 6, resulting in a more squarish but symmetrical design aesthetic, reminiscent of the classic "OmniBalance" design language of old Xperia Z-series flagships. The most defining change in the Xperia 1, as it was in the Xperia XZ2 trio and the XZ3, are the placement of the camera on the back. It is centrally aligned on the upper half of the device, as opposed to being placed on the top-left side like in previous Xperia devices.

The Xperia 1 showcases the world's first 6.5 in (170 mm) 21:9 aspect ratio 4K HDR OLED display officially called CinemaWide, with a 1644 x 3840 pixel resolution and 643 ppi pixel density. This aspect ratio was previously found in LG New Chocolate (BL40). In a more practical approach, the display resolution on regular usage and throughout the UI only is at 420 ppi, which is still considered sharp and is especially beneficial for the battery. The full 4K resolution only triggers automatically when compatible content is displayed on-screen.
