"Just the perceived- Persistence"... Yes because NOTHING ELSE MATTERS ... Get with the program already..



The display is made so I can perceive the image upon it... Jebus...







OLED is poor, and needs another 10 years.. firstly THey produce VERY little light compared to a backlit solution..





So the REASON samsung and ALLLLL oled utilize LONG image persistence is due to this low brightness limitation.



If they blinked it off too quickly, or strobed it, it'd be too dim..





Transition between ON and OFF is irrelevant, if within that frame, they can't produce enough light..





With backlit , just use a more powerful light, DONE... OLED... you need a hell of alot more research and dev to get anywhere close to the output of backlit solutions..





WHICH is why OLED as a viable MOTION-display solution is WAY WAY WAY out.. 10 years minimum..





Lightboost is the ONLY game in town.. Show Image



STAAAHP, PLEASE JUST STAAAAHHHP!



Brightness is just fine on OLED, certainly good enough for desktop displays or TV's and contrast is unbeatable (not to mention view angles, light bleed, etc). And you have it the wrong way round, if your switching time is fast you don't need to resort to a hack like "Lightboost" and you can keep the display on all the time without introducing a strobed / flickering display. Which do you think is better for your eyes?



Samsung's image persistence has absolutely NOTHING to do with brightness levels. They used slow transistors... that's all.



All OLED needs is good transistors used in the matrix. And it won't need 10 years, it's here now (although a bit expensive still):

And here's an interesting article:

See the section on response time and motion blur.



Now can you please stop spreading disinformation....



You ignorant F00L

OLED is at least 10 years away.. at this point, it's bluring aspect is no better than plasma.. which is extremely blurry compared to Lightb00st



Again, you're stuck in an error of terminology..



Motion blur,,,,, can result from many different things.... because OLED can't be easily strobed AND produce enough brightness at the same time... it MUST use the sample-hold method to display your images..



So even if you have 0.1ms transition time you need around 16ms of persistence to adequately produce very bright images...



Okay, now we get to the meat and potatoes. I finally understand what you're saying. At 60Hz on a sample and hold OLED display you will get motion "flicker", not blur. Blur is a misnomer for this type of artefact. The perception of blur in this case is a psychovisual one, not a physical one.With OLEDs the image does not persist beyond the frame time at high frame rates, but with LCD it does. However with OLED the image persists for the whole frame time whereas with LIGHTBOOSTED LCD it persists only for however long the backlight is on for (although it still suffers from ghosting on slow panels).The problem is that your eyes expect a moving object to be halfway between the positions at half the time, but it jumps from one point to another. With LCD blur, it's not dependant on eye movement, but rather the slow response of the display. So flickering the backlight creates black frames in between so you can ignore the position between the frames, your brain fills it in as being in between.Some OLEDs do use strobing and eliminate this, but it requires a very bright panel to make up for the lost "on-time".The solution to this is to have faster refresh rate and higher framerate source material OR brighter panels to make up for the light lost by strobing.I prefer the former :) But it's not likely that movies, etc. switch to 240FPS or higher any time soon. :(The Oculus Rift Crystal Cove headset uses a strobed OLED panel, but it's able to get a way with low relative brightness because it's a headset and the panel is the only light you're seeing.Personally, I can live with something like Sony's PVM-2541 panel which uses 7.5ms persistance and 9.2ms black frame. Better than 120Hz LCD, but not LightBoosted 120Hz. Bright enough, fast enough, smooth enough motion. Better colour reproduction, contrast ratio, efficiency and view angles than LCD. But still too expensive.Point is, OLED will improve, there are already 5000cd/m2 OLED displays being developed, so even strobed panels for lower framerate source material will come. I don't think it's 10 years away. Unfortunately it seems Sony is getting out of the big panel OLED market which leaves only LG developing these.
