First Dual-emission OLED Display in a Phone

roc_face writes "Japanese electronics joint-venture company ELDis has come up with the world's first dual-emission organic light-emitting diode (OLED) display for a mobile phone. This means the screen can be viewed from both sides. It was on display at the annual Flat Panel Display exposition in Tokyo this week."

    Dual-emission OLED Display
    Oh my, lots of technical words :) I suspect that I'm a little after in technology. I haven't even got a cell phone :p

    Wouldn't that mean that all the text on one side of the screen would come out backwards?
    How useful is that?

      Well, if the phone is closed, then the image flips around. Say for caller id, or an e-mail that's come in which can be navigated with a jog dial.

      It seems like a much better solution than those slide-out keypads on something like the Sidekick. A hinge is an easier mechanism to work with.

    Cool, with this device and a mirror I will be able to watch two screens showing the same image at the same time.

    Seriously though, it will make it very hard to hide from your friends what a lousy nibbles player you are.

    I'm sure there are better uses for this tech than cell phones.

    It's all fun and games until your signifigant other sends you some homemade porn during a business meeting.

    It strikes me that this has a number of great applications, above mobile phone use.

    How about Roadside Signs which are readable on both sides?
    (for that "I wonder what exit I just missed feeling)

    Also, laptop displays that can be viewed on one side while an over head projector reads the other?

    I like this tech. Anyone got any numbers for brightness and power consumption?

      With a bigger version of this kind of screen, you could play a proper game of Connect Four.

      It might be adopted pretty quickly by the military though. It would be a great upgrade to those plexiglass tactical map displays you see in every modern submarine movie.

      Or they could just mount another piece of metal on the other side of the poles... I wonder which would be cheaper?

    Here's an informative article from The Economist which explains that we should soon be able to mould screens and use them in broad daylight.

    OK Guys- the jokes about using a mirror to see both screens and spinning your phone fast are not that funny. This has serious uses, not to mention it is a great example of the mythical OLED technology finally coming to market. For example: you know how your flip phone has that single line of text for caller ID or whatever on the outside? What if it had a whole screen, and you could see the person's picture when the called. How about if it were a viewfinder for a now-smaller ELF like camera? It is clunky moving an open phone around to take pictures. Now you can have Geiss like effects when you listen to your phone as an MP3 Player too. In other words, it just provides the possibility and the convenience of doing everything (non-call related) with the phone closed, that you normally require the phone open for.

  9. I suppose dual-emmission sounds more impressive... by magickalhack · · Score: 4, Interesting

    They consume much less power than current devices and have faster response times.

    This seems like a much more interesting fact about them than that they can be viewed from both sides. I suppose one could take advantage of the dual-viewable nature, but it seems like something we already have an adaquate solution for: place a screen on each surface you want to have a screen on. Duh! ;-)

    On the other hand, I suppose the 2 sided viewability could be potentially beneficial to hybrid tablet PCs, which until now have had to rely on fragile-looking swivel mechanisms to rotate the screen between laptop and tablet functionality.

    Any indication as to whether or not the images on each side are identical (i.e. the back is a mirror image of the front) or if they can be controlled independantly?

    To this day is it not known how the ancient Egyptians managed to build the pyramids without being able to read their cell phones from both sides. One theory suggests rotary technology; more audacious mavericks wonder if they perhaps did not have phones at all.
