Beijing, March 17 : OnePlus will launch its flagship 9 series on March 23 and now a new report has claimed that the smartphones will come with a low-temperature polycrystalline oxide (LTPO) panel with adaptive refresh rates from 5Hz to 120Hz. The resolution of the screen is said to be 2K+, which is how Chinese companies often mislabel QHD+ or 1440p, reports GSMArena. A low-temperature polycrystalline oxide (LTPO) display is a special kind of backplane technology designed for OLED screens. OnePlus is likely to launch the OnePlus 9 series with 65W fast charging support. The OnePlus 9 and 9 Pro are likely to feature a 4,500 mAh battery. OnePlus 9 Lite will borrow a lot from the recently launched OnePlus 8T. It may feature a 90Hz or 120Hz AMOLED display, and a quad-camera setup similar to the OnePlus 8T. It will even get super-fast 65W Warp Charge support, reports Android Central. The OnePlus 9 and 9 Pro will feature Qualcomm's latest 5nm chipset, the Snapdragon 888, but the OnePlus 9 Lite will be powered by the Snapdragon 865 instead. Meanwhile, the OnePlus 9 is reported to feature a 6.55-inch full-HD+ (1,080x2,400 pixels) display with a 120Hz refresh rate and a 20:9 aspect ratio. The handset may ship with 8GB of RAM, 128GB of storage, and OxygenOS based Android 11 OS. /IANS
