But sadly, there is NO BFI implementation whatsoever, and this is obviously because LG still wants to hold the technology back because it would make ANY LCD obsolete overnight. So what could be achieved with a simple BFI implementation? We could have around 2ms persistence at any refresh multiple of 60.
This means 60hz could look as clear as 480hz, which solves the blur problem with retrogaming on flat panels for good.
240hz BFI is a nice balance for performance/competitive games, and because it's only a 2:1 BFI brightness isnt impacted that much and due to the high refresh input lag would be unnoticeable.
And remember, we're talking OLED motion clarity, which is around 1.5x clearer than a LCD's due to instant response times.
But how could sub 1ms be achieved? Through a technique called Rolling Scan, which was used on the LG CX/C1 for 120hz BFI modes.

By using this technique, at only 50%, sub 1ms persistence could be achieved at 480hz on an OLED. 50% less visibility means 50% less persistence, which at 480hz is 2.08ms. Cutting that number in half means 1.04ms. However, because an OLED is 1.5x clearer than an equivalent LCD, this number could be translated into 0.64ms! In other words, the equivalent to 1440hz without crappy crosstalking or patented technologies such as ULMB 2.0.
A Blur-free flat panel is already possible, but because it would make competing displays and technologies obsolete, they wont give it to us, yet.
