OLEDs dont have ghosting like LCDs do by merit of how each display technology works. LCDs rely on a physical property of viscous liquid crystals having to flow and bend polarized light and so there is a physical time constant/delay to switching on and off pixels (and thus “ghosting”, an after image of rapidly moving sprites, is visible). OLEDs however can switch basically at the latency of the tft backplane which is on the order of nanoseconds (since diodes/transistors switch very quickly, much too fast to be noticeable by the human eye). This is actually the property that is used to multiplex the rapidly flashed columns to look like the whole display is lit due to the persistence of vision to our eyes. This banding/interference pattern is actually an artifact of the multiplexing (lighting a single column at a time and scanning left to right rapidly, etc). In the driver settings you can actually adjust the multiplex scan rates and alter duty to change brightness both of which can minimize this effect.
