The display specialist TCL CSOT has reportedly demonstrated a display for potential next-gen mobile devices that can support refresh rates from 1 to 144 hertz (Hz). This would improve on even the best smartphone displays of 2022, which can only get up to 120Hz in the same respect. Like these panels, TCL's prototype also has LTPO technology.
