This is Flat Panel General & New FP Tech
. Eventually, this could filter.
But it has excellent applications for home theater gaming of the future, since this technology scales to HDTV-sized LCD displays.
In addition, I'm working more in the gamut of home theater computers and gaming.
Though you can play videos off a PC, too, which can get benefit from the strobe backlight (though works best with 120fps native material)
Also, large size home theater LCD's with strobed backlights do exist (see Existing Technology
) in the form of scanning backlights, but they have not optimized them to work well for video game purposes, and they unfortunately flicker excessively at 60 Hz, and they don't connect to computers or consoles at 120Hz, and the scanning (instead of strobing), has pros and cons. There's too much input lag because of motion interpolation (60Hz->120Hz). Another con is scanning does not seem to reduce motion blur nearly as much as strobing, due to backlight diffusion issues. Still a vast improvement, at least for the well designed ones (e.g. Elite LCD HDTV)
Long term, for video-sourced material (sports, opera, documentaries, etc) what we need is more 120Hz-native source material to permit flicker-free strobes from various strobe technologies without using motion interpolation. Sadly, it'll be 10+ years before this happens. The people at NHK was wise to decide to make 120Hz a feature of 8K. An 8K better-than-IPS LCD with a configurable 120Hz strobe-or-steady backlight, might be what we're seeing in our home theaters in the 2030's if they don't fix the OLED flaws by then. The end of the CRT era means we have wonderfully steady flicker free pictures, but terrible motion resolution, which we have to band-aid with motion interpolation, or stobing, and that's no good for home theater gaming when we connect our Xbox2160's or Wii5's or whatnot to our 8K UHDTV in a couple decades from now.
Then again, it's a matter of a point of view:
Finite framerates? Bandaid.
Finite resolution? Bandaid.
Non-holographic 3D? Bandaid.
Say, for a motion fluidity videophile (sports and games instead of film, etc) -- We can only strive our best, replace interpolation with true frames. But to avoid strobes, we need an a silly framerate (e.g. you need 1000fps@1000Hz sample-and-hold in order to equal the motion clarity of 60fps@1ms strobes). Do we compromise by avoiding strobes and going to an insanely high framerate? Even though there's diminishing returns beyond 120Hz, it's worth noting for sample-and-hold displays, the jump between 60fps->120fps is 50% less motion blur, but the jump from 120fps->960fps is 93.75% less motion blur. Likewise for impulse-driven displays, the jump between 1/60sec strobes(@60Hz)->1/120sec strobes(@60Hz) is 50% less motion blur, but the jump from 1/120sec strobes(@60Hz)->1/960sec strobes(@60Hz) is 93.75% less motion blur. All scientifically proven motion blur equivalences
. Many CRT's have 1ms phosphor decay, so that provides the 1/1000sec strobe equivalence or the sample-and-hold display motion equivalence of a theoretical 1000fps@1000Hz display (for comparison's sake). Even though some say going beyond 120Hz makes no difference to the human eye, this is a plainly wrong assertion, due to scientific testing, as the many links to research papers show. Spiking far down the curve of the point of diminishing returns is another clearly noticeable 43.75% improvement on the 50%, so clearly, the ultimate is well far beyond 120fps, showing it's worthwhile to jump all the way to 960fps (darn near 1000fps real-time). But it'll never be practical to have 1000fps sports TV broadcasts playing in real time (non-slo-mo) at 1000fps on 1000Hz displays, for the CRT perfect motion effect on a non-flicker display. Impractical, bandwidth-wise for the forseeable future. See.....Anything less than ~1000fps is a band aid from this point of view. (real time playback 1000fps@1000Hz) Instead, we depend on interpolation or strobing/scanning (or combination thereof) to get the good motion resolution.
.... So, what's a motion videophile to do, for sports and video games? Live with motion blur? Sure, that's one thing. But let's welcome technological improvements such a compromise balance between a higher framerate (e.g. 120fps @ 120Hz) combined with interpolation (for those that hate flicker) or strobes (for those that prefer non-interpolated, or when low latency/lag is needed for games). Tough compromise. So far, 120fps@120Hz+strobed backlight is a really good compromise for PC users wanting a flicker-free zero-motion-blur effect.
.... The number 60 Hertz is a bandaid invented for a practical reason, based on AC electrical frequency, early TV sets synchronizing refresh to the electrical grid. For video/documentary/sports/game material, we need to say goodbye to 60 Hz in the next two decades. A few hints are showing through, top-end gaming LCD's, the NHK 8K 120Hz, and a few other 120Hz initiatives are slowly beginning, and may spread. It's a small step, even if 120 Hz is, too, also a bandaid (but one that is above flicker fusion threshold for most people). It will take a long time (even two decades or more) for 120 native to replace 60, but the trend is starting to show (bleeding edge territory, ala HDTV in the 1990's). Some of us will want motion blur for many things, like for movies, etc, or for artistic reasons, but other times we want to avoid motion blur forced upon us (and let our eyes naturally create motion blur instead for us), by eliminating motion blur limitations in the source and in the display.
.... And movie needs are a bit different for many people, even myself (sometimes we WANT the motion blur effect of 24fps or even 48fps), etc.
Now I'll go back onto the topic of zero motion blur flat panels for video gaming.
The ones that are here today, the ones that we can buy today, with what appears to be world's least motion blur for a non-CRT display (without the input lag of interpolation) are now the LightBoost2 strobe-backlight-capable monitors.Edited by Mark Rejhon - 12/18/12 at 9:41am
