Over 1000 watts of LED ribbons ordered!

Three different brands of LED ribbons have now been ordered from several suppliers. The current working goal is to create a backlight that is 150 watts per square foot, with 10,000 lumens per square foot. The brightest ribbon I’ve ordered is 22 lumens per LED, and 900 LED’s will be put in a 23″ computer monitor. LED’s can also accept surge current for short time periods to provide over 50 lumens per LED. For ultra short strobes, I can exceed 25,000 lumens per square foot. This is enough strobe wattage to make LCD have less motion blur than CRT.

Total amount of all orders is 80 meters of LED ribbon (4,800 LED’s at 60 LED per meter, using brighter #5050 LED’s instead of dimmer #3528 LED’s), which is enough for at least three computer monitors. Some are actually for R&D — including backlight diffusion tests, brightness tests, and overvoltage failure tests.

High wattage is necessary to more accurately emulate CRT scanning flicker using a scientifically proper sequential scanning backlight (FAQ) — see how ultra-brightly CRT phosphor shines for a short period in high-speed video of CRT scanning. Less than 50% of existing scanning backlights have significantly noticeable blur elimination, and most scanning backlights dim the picture. The BlurBusters scanning backlight design is scientifically targeted at the goal of maximum motion blur elimination, with minimal disadvantages.

Good idea. I’d like to do that, once I get a critical mass of registrations. Over the short term, I’d rather have more registered people replying than anonymous posters, since this is a rather technical site that requires a lot of explanations, and many people try to contradict real science — which can be a distraction in itself!

I’d love to see this done on larger TV’s eventually. Doing this experiment on a larger TV will be quite a challenge, and can be extremely expensive. Odds are, you can accidentally crack the LCD during the modification, and that becomes an expensive mistake.

Eventually, manufacturers may do this before a hobbyist dares to try this modification — they are slowly heading towards this direction, but at 150 watts of LED per square feet (required for CRT phosphor brightness equivalence during short strobes), they don’t want to sell an overpriced TV that is hard to market, since scanning backlights only gives extremely clear benefit for certain situations (full frame rate material – computer use, 60fps+ games, sports).

However, I think we’ve got a few years of hobbyist creativity in this arena, since the LED technology is already here, and the panel technology is already here. Some of us are willing to try — like my 23″ monitor experiment.

Can’t wait to see the results. I might attempt to duplicate your project if it is successful, just so I can see it with my own eyes. Would be interesting to try the experiment on a larger display such as a TV as well.

PS. If you want more comments you may want to consider allowing comments from people who don’t register. Just make sure you install the Askimet plugin or you’ll get flooded with spam comments. I was going to leave a comment earlier, but I was too lazy to register until now. There might be more people like me.
