Digital Ink On Billboards
cdneng2 writes "The New York Times has this article on
a revolutionary new billboard. It uses digital ink, versus the typical CRT,
LCD, Neon, or Plasma displays that are so prominent on the newer billboards that
wastes electricity. From the article: 'By creating a paste made of tiny helix-shaped particles that can be minutely manipulated with electric charges to
reflect light in highly specific ways, Magink
can produce surfaces that look like paper but behave like electronic screens,
rendering high-resolution, full-color images without ink - or, as Magink
executives like to refer to the process, with digital ink.' The billboard
can display images at 70 frames per second." You can find more articles on the billboard technology on the Magink website.
Why is it that nowadays, any new cool thing is invented either for military or advertising use?
The day advertising and the military merge, we'll be in a world of hurt. They'll end up creating a pop-up that kills, I tell ya.
Digital ink = finger painting.

Print quality image
Combining 5mm pixel pitch, an RGB color model with 4096 colors, and a superior contrast ratio of 14:1, magink digital ink technology achieves an extremely natural look that very much resembles the look of printed images on paper.
Compatibility to outdoor lighting environment
magink's digital ink display billboard is reflective of incident light and requires no integrated illumination. Light that falls on the display from either the sun or external light sources is actually beneficial to the visibility of the image. A beautiful image is maintainable under the full range of daylight conditions.
Low energy consumption
magink display does not require any power to maintain an image: the image is held under power-off conditions. Only when replacing one image with another does the display require punctual application of power in order to set the new image.
Since energy is needed only for refreshing the image and since magink's digital ink reflective display does not require back lighting, power consumption is low yielding less energy consumption, less heat dissipation and a longer mean time between failure (MTBF).

Now, when I'm driving to work in the morning, a huge TV ad can distract me from driving, talking on my phone, reading the paper, shaving, eating, and putting my pants on.
How am I supposed to get ready for work!?
I have a question. I haven't read into digital ink to any great extent,but I was wondering how easly these things coud be defaced? Do magnetic fields have any effect on these babies? If some sort of a electrical charge was dragged over the board how would this effect the image?
...runs Windows.
Is this really the best choice for something that thousands (or tens of thousands) of people will see each day as they drive down the highway?
At the PATH terminals in New Jersey, they have "PATHVision" displays. They run Windows. For a long time, virtually every day, pretty much half of the terminals were displaying an error dialog or worse. I also think I saw one of their ticket vending machines displaying a BSoD.
I really wish that companies who come up with stuff this cool would not depend so heavily on Windows. Imagine driving down the highway and seeing a gigantic, 50-foot-wide Blue Screen of Death. If my experiences with the PATHVision monitors were an example of what is to come... well, it could happen!
Here is what happens when airports depend upon Windows...

Same reason you don't have back lighting on a book: it is an absorbtive, not emissive, technology. The coloured elements seem to be opaque, so backlighting wouldn't work.
There seems to be no reason why they couldn't scale the technology down to PC size. But I think they have targeted the big-ticket applications for their first market - not a stupid idea. If they can replace "million dollar" displays with "80,000 dollar" ones, there are some *big* shot term profits to make the money to fund the mass production line to manufacture cellphone displays at the millions/month level you need to get the costs down.
Consciousness is an illusion caused by an excess of self consciousness.
Let's try scaling this technology up the curve a little:
- 10-bit color (4096 colors) will become 16-bit and then 24-bit.
- 5mm pixels will become 1mm and then 1/10thmm
- the borders between the pages appear 1 pixel wide, and will thus vanish
- cost of $8,000 will drop to $2,500, then $500.
Yes, looks good!

If this were advanced sufficiently, I could then even play bf1942 on this once I realized said female was imaginary and never came over in the first place.

Some days my car should be red. Some days blue. Some days a nice mauve. Then polka dots that change colors. How about flames that really flicker? Can't imagine flames on my wagon, but why not? Checkerboard? Heck, you can actually play checkers! Or chess. Or Othello. Backgammon. Hah, you can even play tetris. I can have my phone number flash on the side when I pass a cute girl (oh wait, I drive a wagon). I can have messages flash on the back telling that moron driving 30 in a 50 what I think of them. There's a world of possibilities here!

response time is different from refresh, i'll explain. If you take a normal LCD they usually have a 60Hz refresh and say 25-30ms response. What this means is that the LCD can show 60 different frams every second. However, the response time measures how long it takes for the LCD to change frames, the longer the time the longer the last image that was on the LCD is displayed, so if you have a high response time (25ms is considered normal but not good) then you will get "streaking" effects, where the previous frames overlap with the new frames. This can cause a horrible image and is very noticeable when the frames are very different e.g. fast motion graphics (films, games). Newer LCDs report a 16ms response, which makes streaking almost invisible in most cases. So you see, this is why I wanted to know what the response of the ink is.
Also you may be wondering about TVs and their response time, T.Vs and Monitors (CRT) don't have a response time (or more to the point its the same as the refresh) because on a CRT screen the previous frame is not remembered as the "pixels" on a CRT so to speak, need to be constatly energised to display anything, so the second that the cathode ray stops hitting the phosphor the image dissapears, thus no reponse time.
I spent ages trying to think of sig, but never did
Yes, you can shine a flashlight through paper from behind. But the losses are horrendous - I woudl ahve though >95%. Consider how close you have to bring the flashlight to see the picture from behind, vs how far away you can take the same flashlight if you are shining from the front. You woudl be much better spending your energy shining a light from the front - and a floodlight is probably much cheaper than an equivalent area of computer backlight.
Horses for courses - if you really want an emissive display, go for the current technologies of LCD or plama. This is something difffernt and, potentially, better. I took my laptop into the garden yesterday - and had great difficulty reading it because of sunlight. This would get easier to read with more light.
Humans are creatures of light; emissive displays are creatures of dark. Putting the two together requires compromises: avoid directt light sources, fear reflections. Turn the light down and your screen becomes more readable but fine print documentation becomes less readable. Turn lhe light up and the screen washes out as the fine print comes into focus. With absorbtive displays, the two become visible together. And reduced power consumption has got to be good. This might make e-books worth having. Battery life greatly increased, because power only consumed when you move the page (system can completely power down between button pushes), readable in a bright light.
Remember LED watches, as mocked in Hitchhikers Guide To The Galaxy? LCDs (non-lit) wiped those out almost overnight, because using power for a continuous, slowly changing display is ridiculous.
Don't expect new displays to be identical to old - evaluate and exploit their differences. If you analyse them, both CRTs and LCDs are rotten displays - but they are the best we have got, so we use them everywhere. Sometime soon someone is going to come out with a good absorbtive display - maybe this one, maybe another - and that will spread like wildfire.
