"Traditionally plasma and CRT TVs deliver the sharpest motion owing to their impulse-based display characteristics, but alas. All the 4K TVs available to buy on the market (including LED LCDs and OLEDs) at this time of writing are hold-type displays, where one frame is displayed continuously until the next frame replaces it. As our eyes track the movement on screen, the persistence of the preceding static frame in our retina contributes significantly to what we perceive as motion blur, otherwise known as “sample-and-hold” effect.
The most straightforward way to reduce motion blurring on sample-and-hold displays involves inserting an artificial frame between the original frames, but this type of interpolated motion compensation invariably introduces interpolation artefacts into the picture. For example, you may notice the ball tearing up slightly as it whizzes past the crowd, or shimmering artefacts around running players.
A more promising technology to improve motion clarity on hold-type displays is black frame insertion (BFI) which, as suggested, adds a black frame between the original frames in an attempt to mimic the low retinal persistence property of impulse-type displays, although BFI usually incurs flicker and brightness drop due to how it works.
Over the past few years, Samsung has developed the most effective black frame insertion algorithm on their high-end models, providing the clearest motion among all the 4K TVs we’ve tested, as you can see for yourself from the following motion pursuit camera capture of the leading 2016 televisions"
