What just happened? Mobile World Congress has started in Barcelona, meaning companies are now showing off and previewing their new products at the expo. One of these is Samsung Display, which has just revealed some of its new tech. It includes a 7.2-inch foldable OLED handheld gaming console, a 500Hz QD-OLED monitor, a 240Hz OLED laptop, and more. The handheld device, called the Flex Gaming, is a concept that is essentially a Steam Deck-like handheld that folds in the middle, much like Samsung's own Galaxy Z Fold and Z Flip phones.The Flex Gaming features a pair of joysticks and a d-pad. There are recesses on each side of the OLED screen for the joysticks to sit inside when the device is folded. There's also a button with an N marked on it and a USB-C port on the bottom. It's still very much in the concept stage, so there were no technical specs revealed.Samsung did show off a Flex Gaming handheld concept at CES 2023, though it had a flip-open lid rather than being foldable.Also on show will be what Samsung calls the "world's first 27-inch 500Hz QD-OLED monitor." Featuring a 1440p resolution, reports about this monitor first emerged last November. No word yet on a release date.In addition to the blistering fast OLED monitor, Samsung is showcasing its 240Hz OLED laptop. In 2022, Razer announced the world's first 240Hz OLED laptop display in its Blade 15, combining the stunning image quality of OLED with incredibly fast refresh rates in a portable PC.Samsung says that a highlight of its MWC exhibition will be the Seamless Color Studio concept, where OLED technology is seamlessly integrated into devices, such as smartphones, tablets, laptops and TVs. The company talks about watching a show on a smartphone and seamlessly transitioning to a TV or browsing products on a laptop and completing the purchase on a smartphone, with all the devices uniformly displaying seamless color consistency across different screens.Also being showcased is the OLED Tile demonstration, which features full-screen technology with ultra-thin bezels to create the appearance of a bezel-less, massive single display. Samsung said a breakthrough in bezel-less technology has resulted in a bezel that is 40% thinner on all sides compared to the average bezel width of products currently on the market.Expect to learn more details about Samsung Display's MWC products over the coming days.
