The Dollar Guy No I can not.

Just lower the refresh rate

@@spark198rus Or increase it beyond 20khz, good luck.

Good idea!

Good idea indeed!

That would be too much since theres only 2 colors

@@probreyene9595 he's not saying to add a color, just replace the current black with vantablack.

Yea but i though contrast is already great

I wander if you can drive it such that it produces a recognisable tune.

keoni29 A truly cancerous sound.

It sounds like thousands of butterflies

I hate stuck pixels :D just recently noticed one in the middle of my laptop screen :D drives me mad..... always purpleish green little fucker

The pixels in your laptop and the pixels in this screen are different.

***** No. Why?

Flipdot pixels are electro-mechanical so they actually get stuck much more often than purely electronic (OLED and SED) or electro-chemical (LCD and Plasma) ones... DLP is also electro-mechanical just like Flipdot however because DLP is built as a microchip and is protected from the air in a vacuum, DLP is also much more reliable than Flipdot. Flipdot requires a lot of power to drive each mechanism because they are huge motorized things and they are exposed to air.

666th like.

I think its the screens limit that makes the blocks.

@@LordGryllwotth or is it all the power between the pixels? 🤔🤔

It's all video compression really. You can't have real images as frames if you don't want a 150GB/min file

​@@paskky913photos are 15mb~ on highest quality for my s21 i think your right lol

Nop, it needs a ton of good digital timing to work

There is no sound? Make sure you check your room for snakes before commenting.

There was such a story, written by Bruce Sterling and William Gibson. It's called The Difference Engine. The computer age arrives a century early. In the novel, there are theaters that use these screens. The people who program the movies are called "clackers". It's a favorite. I've wanted to see a film adaptation for a very long time. Now, it can be done, but Hollywood is too busy remaking every possible movie that already exists.

fairly sure the basic premise of this kind of display is quite, quite old. Though perhaps the driving electronics to allow it to function decently are not.

AmazinChannel So does crt

If it is like other displays, it can only flip one column at a time due to the limits of multiplexing and every other row to keep neighboring rows from interfering with each other. Also it can only do that in one direction, so it has to go through that process once to turn pixels on and again to turn them off

complety fine turns all flipboard black to white one at time very fast. and you see there multiple invidual boxes and they synced starting from top corned

that would be easy to mitigate

The back EMF would be solved with a simple diode (flyback). However you may be onto something with there being a limitation in how quickly all the pixels can be changed. Then again given how large the pixels are, it's not going to be too much more demanding than other large screens. I guess if there is a limitation it is overcomable but they didn't go down that path for this particular setup.

"One tenthTH"? That doesn't make sense.

ObiTrev yes

Actually the refresh rate is super low, the frame rate is super high, refresh is the whole screen if it were flashing on and off. Frame rate is between each pixel, and since not every pixel is changing with every frame, it can charmed really fast

@@braydenhancock3907 🤓🤓🤓🤓

that would be awesome, like reverse oscilloscope music where instead of the visuals being generated by the music being made a certain way the music is generated by the visuals being made a certain way

@@orangejuliaa What about both ways at one? Image would be constructed to generate sound that draws the same image on oscilloscope :)

I kind of agree, but i just want to point out that this display is very much digital. More digital than a typical led backlit lcd display.

That's the same for eink displays

I remember going to Kyiv in the summer of 2022. All ads on the streets and the metro were stuck in February. Truly a time capsule.

@@anonymoususer8517 these work by the same optical principle, just on a larger scale

​@@anonymoususer8517they will fade after a little while, depends on the screen how long it's gonna take

Flipdot isn't the most stable thing. ¯\_(ツ)_/¯

resting!

DelphiTheDolphin Dw, just give 'em a spin, they will start up again

They need to get a refund. Hope its under warranty.

What a twist! Thanks M. Night Shamalan!

Flip dot displays typically only consume power when each individual dot is flipped. From what I can find online, each dot typically uses somewhere between 1 and 2.5 watts of electricity for 1 to 2 milliseconds each time the dot is flipped. At that rate, if you wanted to flip every dot just one time per hour, this 74,088 dot display would consume between 0.074 and 0.370 kilowatt hours of electricity. On the other hand, if you wanted to flip every dot once every second, this 74,088 dot display would consume between 266 and 1332 kilowatt hours of electricity. As you see, the power consumption can be considered extremely little on average if you only update all the dots on the sign once a year or could be considered extremely high on average if you update all the dots on the sign multiple times per second. Power consumption is determined by the way you use it. In this application, I think the power consumption is probably quite high.

If it take 2 mJ of energy to flip a disc, or 2 mW at 1 Hz, then it's only 150 W for the whole display.

Jet Li electric doesn't exist

It's multiplexed in order to not cause high power spikes, it means pixels are flipped one after the other, you can see it when the screen goes black to white

They showed it displaying white noise. that must've drawn A LOT of energy

@aaaaa not literally on the spot replace them directly... Kinda like when a part of it is broken or damaged... Then that's the time to replace it and all other parts could be to use in other else though like scavenging parts for other damaged jumbotron

Not really sure about how long it could last exposed to the elements but ePaper would probably be even better. Since it is just moving pigment around and you only need to use energy to change the pixel state. They also have colored variants, so at least some more variety. Also less prone to getting stuck and way smaller minimum pixel sizes.

@@jansustar4565 that nice idea too the problem is, There is no company who make that huge epaper

Why not just using those rotating triangular prism thing then ?

"Pictures not videos"? That doesn't make sense. Are you sure you don't need some sort of punctuation in there? Maybe look into that so it can make sense.

next time they make cube that spin it has green red blue and black, but it wont work. black and white works

There's enough pixels. Terminal output can be as low as 320x200 if you use CGA resolution. That's still enough for 40x25 characters, same as the C64 for example. This display looks like it has more then 320 pixels across so it could easily handle it. Here's a vid of one displaying text. kzfaq.info/get/bejne/bdWDe5CSv7HdhWw.html It just happened to be in my reccommended next to this video.

sure. get a 15 pin to rca converter, and use an arduino to drive the display. tho youd be stuck at tv resolution at best.

Yes, but screen would be huge

Also you can try create your own with smaller dots

cat /dev/random

Except that "physical," "analog," "noise," and "old" aren't brand names; and that all actual sound that we hear is physical, and thus analog, anyway. And that a TV doesn't have to be old for you to hear this sort of sound on it.

UNLIMITED POWAAAH

2 years late but, flipdot displays have advantages such as low power consumption, high visibility, longevity, and a unique retro aesthetic. However, they also have limitations, including limited color options, complex maintenance, and a potentially higher upfront cost compared to LED displays

I came to the comments to say exactly this lol

for much smaller displays, flip dots are great because they don't require power when they aren't being flipped. They're also very easy to read. Something of this scale is purely for entertainment, you'd be better off using LED's.

Gazelle Samyueru Maybe displaying time and temperature or a menu. Readable in full sun and doesn't need to be updated a lot (time needs to be updated once in a minute, and not all pixels).

I think it's an interesting invention. Flip-Disc displays really stand out as a display technology and it shows the nature and evolution of displays. It uses the same exact mechanics no matter how limited it may be. All display technologies have a pixel resolution, we have not really advanced further than this idea, we only increased resolution and colors. Unlike other displays, Flip-Disc systems don't really hurt your eyes like conventional displays, it does not produce light.

They might not hurt your eyes, but they do hurt your hears ; ) But really, they don't have much to offer and I don't get why they were used here other than for being different. They are great at strong sunlight, but this installation is indoors. They don't use power when the display is not updated, but they constantly change the contents. There are several display technologies which does not produce light. E-ink is an obvious one, but LCDs does have to produce light either, you can simply have a mirror behind it instead of a back light. (Gameboy Advance is a great example for a color display like this.) Not all displays use pixels either, e.g. 7 segment displays, nixie tubes and spit-flap displays. Black and white CRTs don't have a horizontal resolution either.

I have never heard of E-ink before. I don't know how LCDs work exactly so I don't know what you mean by simply adding a mirror to the back. Maybe one day we will move on from the current display technologies and we can simply manipulate light around us to produce visuals. I was watching this video one day and it blew my mind, the idea that when one projects colors, black is also projected: kzfaq.info/get/bejne/ppN_dsmazNK-goU.html Thanks for sharing that information, Its nice to learn something new.

Big Sport Screens, Period.

They’re great at places where you need to wait for your number to be called. No need for speakers; everyone in the vicinity will look. Airports Government transactions Train stations Elections (every click is satisfying) Just an opinion.

+GAME OVER "WE HAVE EVERY PIXEL COVERED" no it wont be popular, too high maintaince cost

I can already imagine it since the screen is black and white it will be perfect for bad apple to be in it

mmh. But we went through most of the 80's with a sizeable portion of computers using 320x240 or lower resolutions. 320x240 is 76,800 pixels, so that gives a good sense of what kind of display this is equivalent to. If you have a PC by the way it's likely still booting in 320x200 even to this day.
