With the OnePlus 7 Pro released last May, OnePlus overcame several challenges such as optimising display panels and minimising power consumption to deliver the world's first 90Hz Fluid Display with QHD+ resolution.
"We believe that the smoothest smartphone display must also be able to deliver a superior visual quality and viewing comfort. We're sure that OnePlus's new 120Hz Fluid Display will be the best you'll lay eyes on in 2020," Lau said in a statement.
According to the company, the new display features the most rigorous hardware configuration in the industry and a handful of exciting technologies, including MEMC technology for smoother video playback.
Other features include a QHD+ resolution, the "most accurate" colour accuracy and 4096-level of automatic brightness control, four times of average Android flagships.
This comes at a time when Qualcomm is bringing full support for higher refresh rates in the Snapdragon 865 system on chip (SoC).
