These days, this is less of an issue - and not at all an issue for the much faster OLED displays. This was how quickly the liquid crystal could change from one state to another, which is necessary to create an image. In the early days of LED LCD, motion blur was caused predominantly by the response time of the panel. Notice how the dolphin on the right is blurred compared to the other 3.

The bottom half is a representation of what motion blur looks like. It's sort of like the moving parts of the image lose focus briefly, then come back into focus when they stop moving (it actually has nothing to do with focus, but the visual analogy works). This is where anything that moves, including the whole image because of a camera pan, blurs slightly compared to when nothing was moving. How about this: black frame insertion is a way to reduce motion blur on LED LCD and OLED devices, which is definitely a good thing.Īll LED LCDs, and the current generation of OLED TVs, suffer from motion blur. Hmm, OK, that didn't really put it simply, and I'm pretty sure I defined a term with the term. Black frame insertion (BFI) is, to put it simply, inserting full-screen black images between the original frames of a source.
